This is only a proof of concept and not a full + * working plugin. + * + * May 6, 2009 Barak | Itkin + * Added new features and several bugfixes: + * - Added handling for image resolutions + * - fixed the behaviour of getting font sizes + * - Added various optimizations (solid rectangles instead of bitmaps, ignoring + * invisible layers, etc.) as a macro flag. + * - Added handling for layer masks, use CAIRO_FORMAT_A8 for grayscale drawables. + * - Indexed layers are now supported + * + * August 17, 2009 | Barak Itkin + * Most of the plugin was rewritten from scratch and it now has several new + * features: + * - Got rid of the optimization macros in the code. The gui now supports + * selecting which optimizations to apply. + * - Added a procedure to allow the creation of multiple paged PDF's + * - Registered the plugin on "/File/Create/PDF" + * + * August 21, 2009 | Barak Itkin + * Fixed a typo that prevented the plugin from compiling... + * A migration to the new GIMP 2.8 api, which includes: + * - Now using gimp_export_dialog_new + * - Using gimp_text_layer_get_hint_style (2.8) instead of the depreceated + * gimp_text_layer_get_hinting (2.6). + * + * August 24, 2010 | Barak Itkin + * More migrations to the new GIMP 2.8 api: + * - Now using the GimpItem api + * - Using gimp_text_layer_get_markup where possible + * - Fixed some compiler warnings + * Also merged the header and c file into one file, Updated some of the comments + * and documentation, and moved this into the main source repository. + */ + +#include "config.h" + +#include + +#include +#include +#include + +#include +#include + +#include "libgimp/stdplugins-intl.h" + + +#define SAVE_PROC "file-pdf-save" +#define SAVE2_PROC "file-pdf-save2" +#define SAVE_MULTI_PROC "file-pdf-save-multi" +#define SAVE_TRANSPARENT_PROC "file-pdf-save-transparent" +#define SAVE_MULTI_TRANSPARENT_PROC "file-pdf-save-multi-transparent" +#define PLUG_IN_BINARY "file-pdf-save" +#define PLUG_IN_ROLE "gimp-file-pdf-save" + +#define DATA_OPTIMIZE "file-pdf-data-optimize" +#define DATA_IMAGE_LIST "file-pdf-data-multi-page" + +/* Gimp will crash before you reach this limitation :D */ +#define MAX_PAGE_COUNT 350 +#define MAX_FILE_NAME_LENGTH 350 + +#define THUMB_WIDTH 90 +#define THUMB_HEIGHT 120 + +#define GIMP_PLUGIN_PDF_SAVE_ERROR gimp_plugin_pdf_save_error_quark () + +typedef enum +{ + GIMP_PLUGIN_PDF_SAVE_ERROR_FAILED +} GimpPluginPDFError;

For indexed images, this can only be + * done if there is at least one free colormap entry. + * + * Release 1.0, 1997-09-06, Gordon Matzigkeit : + * - Handle loading all image types from the 2.0 specification. + * - Fix many alignment and endianness problems. + * - Use tiles for lower memory consumption and better speed. + * - Rewrite RLE code for clarity and speed. + * - Handle saving with RLE. + * + * Release 0.9, 1997-06-18, Raphael FRANCOIS : + * - Can load 24 and 32-bit Truecolor images, with and without RLE. + * - Saving currently only works without RLE. + * + * + * TODO: + * - Handle TGA images with version 2 extensions (image comment, + * resolution, date, ...). + * - GIMP stores the indexed alpha channel as a separate byte, + * one for each pixel. The TGA file format spec requires that the + * alpha channel be stored as part of the colormap, not with each + * individual pixel. This means that we have no good way of + * saving and loading INDEXEDA images that use alpha channel values + * other than 0 and 255. Workaround implemented for loading by + * promoting the image to RGBA, but saving indexed TGA images with + * full alpha information in the coloramp is not supported yet (only + * one fully transparent color is allowed in INDEXEDA mode). + */ + +/* Set these for debugging. */ +/* #define PROFILE 1 */ + +#include "config.h" + +#ifdef PROFILE +# include +#endif + +#include +#include + +#include + +#include +#include + +#include "libgimp/stdplugins-intl.h" + + +#define LOAD_PROC "file-tga-load" +#define SAVE_PROC "file-tga-save" +#define PLUG_IN_BINARY "file-tga" +#define PLUG_IN_ROLE "gimp-file-tga" + +typedef enum +{ + ORIGIN_TOP_LEFT = 0, + ORIGIN_BOTTOM_LEFT = 1 +} TgaOrigin; + +typedef struct _TgaSaveVals +{ + gboolean rle; + TgaOrigin origin; +} TgaSaveVals; + +static TgaSaveVals tsvals = +{ + TRUE, /* rle */ + ORIGIN_BOTTOM_LEFT /* origin */ +}; + + + /* TRUEVISION-XFILE magic signature string */ +static guchar magic[18] = +{ + 0x54, 0x52, 0x55, 0x45, 0x56, 0x49, 0x53, 0x49, 0x4f, + 0x4e, 0x2d, 0x58, 0x46, 0x49, 0x4c, 0x45, 0x2e, 0x0 +}; + +typedef struct tga_info_struct +{ + guint8 idLength; + guint8 colorMapType; + + guint8 imageType; + /* Known image types. */ +#define TGA_TYPE_MAPPED 1 +#define TGA_TYPE_COLOR 2 +#define TGA_TYPE_GRAY 3 + + guint8 imageCompression; + /* Only known compression is RLE */ +#define TGA_COMP_NONE 0 +#define TGA_COMP_RLE 1 + + /* Color Map Specification. */ + /* We need to separately specify high and low bytes to avoid endianness + and alignment problems. */ + + guint16 colorMapIndex; + guint16 colorMapLength; + guint8 colorMapSize; + + /* Image Specification. */ + guint16 xOrigin; + guint16 yOrigin; + + guint16 width; + guint16 height; + + guint8 bpp; + guint8 bytes; + + guint8 alphaBits; + guint8 flipHoriz; + guint8 flipVert; + + /* Extensions (version 2) */ + +/* Not all the structures described in the standard are transcribed here + only those which seem applicable to Gimp */ + + gchar authorName[41]; + gchar comment[324]; + guint month, day, year, hour, minute, second; + gchar jobName[41]; + gchar softwareID[41]; + guint pixelWidth, pixelHeight; /* write dpi?

Lee and Richard A. Redner. +** +** The paper recommends using a hexagon sampling region around each +** pixel being processed, allowing an effective sub pixel radius to be +** specified. The hexagon values are sythesised by area sampling the +** rectangular pixels with a hexagon grid. The seven hexagon values +** obtained from the 3x3 pixel grid are used to compute the alpha +** trimmed mean. Note that an alpha value of 0.0 gives a conventional +** mean filter (where the radius controls the contribution of +** surrounding pixels), while a value of 0.5 gives a median filter. +** Although there are only seven values to trim from before finding +** the mean, the algorithm has been extended from that described in +** CG&A by using interpolation, to allow a continuous selection of +** alpha value between and including 0.0 to 0.5 The useful values +** for radius are between 0.3333333 (where the filter will have no +** effect because only one pixel is sampled), to 1.0, where all +** pixels in the 3x3 grid are sampled. +** +** The optimal estimation filter is taken from an article "Converting Dithered +** Images Back to Gray Scale" by Allen Stenger, Dr Dobb's Journal, November +** 1992, and this article references "Digital Image Enhancement andNoise Filtering by +** Use of Local Statistics", Jong-Sen Lee, IEEE Transactions on Pattern Analysis and +** Machine Intelligence, March 1980. +** +** Also borrow the technique used in pgmenhance(1) to allow edge +** enhancement if the alpha value is negative. +** +** Author: +** Graeme W.

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + Appendix: How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) 19yy + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary.

This also works for N +pointed stars. + +The drawing area can be scaled. + +Control points can be hidden. + +To aid alignment of objects a "grid" can be placed on the drawing area. +This can be either a normal rectangular grid or a polar type grid centered +in the drawing area. +The spacings of the grid can be changed as well as the colors used to draw the +grid lines. When "Snap to grid" is checked then all operations will be +constrained to fall on a grid intersection. (Fun when using the polar grid). +Additionally the third mouse button will constrain the point movement to be +on a horiz/vert (for rect grid) or radial/radius (for polar) only when +"Snap to grid" is set. + +The image that was selected when Gfig was started can also be shown (scaled) in +the drawing area. (Options tag). + +Painting tab +++++++++++++ + +There are three possible mode when painting. + +1) Brush +2) Selection +3) Selection+fill + +Brush +~~~~~ +When the paint button is pressed each object will be rendered/drawn onto +the image using the currently selected ink color. The objects can be drawn +onto the original layer or onto a new layer (either a single layer or +multiple layers - latter is good for animations). When new layers are +created the background can either be:- + +Transparent. +Background (the current BG color). +White. +Copy. + +The last option means that the layer is duplicated from the previous layer +before the draw operation is performed (re good for animations). + +Lines can be drawn in reverse order. This means that reg polygons/curves/lines +that are normally constructed of lines can be drawn starting at either "end". +This is only noticeable when the current brush has fading turned on. +The "Approx Circles/Ellipses" toggle allows the same effects when drawing these +types of objects. + +Note that in the current version any selections present in the image are first +de-selected when Gfig starts up. This is because selections are used to +draw circles and ellipses (unless the Approx. Circles & Ellipses toggle is set). + +Selection +~~~~~~~~~ +With this method closed selections are made of the objects. See selection +tab for more details. + +Selections can only be made on the current layer. + +Selection+Fill +~~~~~~~~~~~~~~ +This method first selects the objects and then fills the selection area. The +selection tab gives more details on how the selections are filled. + + +Brush Tab ++++++++++ + +This tab now contains a preview of the selected brush in black ink. If the +brush is too large to fit in the preview use the mouse button to "move" it +around (as with the brush dialog in the main GIMP - until that brush +patch went in!). + +Four types of brush can be used:- + +Normal brush +~~~~~~~~~~~~ +Simply paints with the current brush - honors fading if any +The Fade option allows the "brush fading" to be selected. I am sure that some +nifty anims can be created with this option. + +Pencil brush +~~~~~~~~~~~~ +Same as the GIMPS pencil. + +Airbrush +~~~~~~~~ +As GIMPS airbrush. The "pressure" can be specified and this is reflected in the +preview window. + +Pattern +~~~~~~~ +The lines are drawn with the currently selected pattern. The preview will +show this pattern. + +Note a patch to enable a couple of "hidden" paintbrush features was recently +posted to the GIMP developers list. The patch only allowed these features +to be called via the UI and not the PDB so they cannot be used by Gfig. If they were exported via the PDB then they would have probably broken a number of +scripts and Gfig itself (number of args changes on the PDB call). + +Select tab +++++++++++ + +This is enabled when using either Selection or Selection+fill types when +painting objects. + +The anti aliasing and feather toggles apply to the selection made when +"painting" the objects. The feather radius can be changed. + +The default selection mode is to add to the current selection so each object +add to the overall selection. The other selection modes are also possible +but you must bear in mind the following:- + +Subtraction/Intersection will not produce any selection if no selection is +elect the area in the target window (AFTER starting Gfig up) and then paint +using this method. + +Replace will leave only the last object selection. + +When the paint type is selection+fill then the objects will be selected +and then filled. The opacity of the fill can be chosen. By default a fill +is performed after each section. If filling onto a single layer +then the fill will accumulate on the first objects painted. This will be +noticeable when opacity != 100. To get around this then use replace mode +OR use a new layer for each selection/fill. (Paint tab). Additionally you can +set the fill to be performed after ALL objects have been selected (useful +for intersection type selections). + +Selection of non-closed objects +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +For objects that are not closed the first & last points will be joined +together to form the closed selection. For arcs you can either fill +as segments or sectors. Note straight lines will not cause any selection to be +made. This can be a little confusing when filling since the whole canvas will +be filled if any straight lines are present on it. + + +Scaling ++++++++ + +When Gfig first comes up the selected group of objects are automatically scaled +upwards to the image size. (If the source image is < 256*256 then no automatic +scaling is performed - change PREVIEW_SIZE in source to alter this values). +By toggling the scale button the objects can then be scaled in the drawing +area. This scaling will be reflected when the objects are drawn. +To reposition the objects on the drawing area use SHIFT + MOVE_OBJ operation. + + +Other ops ++++++++++ + +Double click on reg polygon object selection to get dialog with slider to +selected the number of sides to draw. + +Double click on star object selection to get dialog with slider to +selected the number of points the star will have. + +Double click on spiral object selection to get dialog with slider to +selected the number of turns the spiral will have and it direction. + +Double click on bezier object selection to get dialog which allows you to +control how the curve is displayed and if it is closed. + +SHIFT + MOVE_PNT will break a reg polygon or star into a number of +connected lines. + +When drawing lines if the SHIFT modifier is used then connected lines +can be drawn. + +SHIFT + MOVE_OBJ will move all objects. Note if "snap to grid" is selected then +the new point will be constrained to fall on a grid intersection. + +Mouse button 3 + "snap to grid" will constrain the point to fall on one of the +two gridlines it was originally on. + +The ">" and "<" buttons allow you to selective move through each of the +objects in the collection. The "==" returns the display to normal. If the +"paint" button is pressed then only the single object displayed will be +drawn into the target window. Also when in this mode pressing the shift button +will temporarily show all the objects in the collection. + +The the options tab there is now a toggle that allows you to turn the +position display on and off. + +Gfig objects +++++++++++++ + +The upper right part of gfig contains a scroll region when different +collection of objects can be found. When button 1 is pressed on an entry +the small preview window will be updated with the objects contained in +the selected figure. These objects can then be loaded into the main window +by using the "Edit" button or the "Merge" button. In the former case +the objects area will first be cleared before the new objects +are added. In the latter case the objects will be merged into the drawing area. + +When a collection of objects is altered to small image of a floppy disc +will be placed next to the entry signifying that this collection needs to be +saved. If a red cross appears here then the file associated with the +entry is read only and cannot be saved to (it can be copied however). + +Button 3 brings up a popup menu that allows collections to be saved away to +different files. (Accel. keys also exist for some functions). + +The buttons on the right of the list area allow the following operations:- + +Rescan:- +This popus up a window which allows you to add directories to the internal +gfig-path. A (re)scan of these directories can the performed. Note any +modification to the gfig-path will NOT be mirrored in your ~/.gimp/gimprc file. + +Load:- +Allows you to load a single collection of objects. + +New:- +Create a new collection. Note that until this is saved away to a file then no +filename will be associated with it. (See status area). + +Delete:- +Popups a dialog asking if you wish to delete the entry selected in the list +box as well as on disc. + +Additionally button 3 over the list area allows the following:- + +Save as...:- +Save collection to new filename. The collections filename is also +changed to this new name. The original name is NOT deleted from the disc +but it is effectively removed from the list selection area (actually it +is overwritten internally). + +Save:- +Save the currently selected entry to disc. + +Copy:- +Make a copy of the collection. + +Edit:- +Same as the "Edit button". + +Double click on entry with Button 1 popups up a dialog that allows you to +modify the nme of an entry (similar to other list areas in GIMP). + +Bezier +~~~~~~ + +OK my maths is a little rusty. The bezier stuff is only very simple. However... +I have tried to abstract as much as possible the bezier calculations from +the drawing of the control points / painting on the screen and in the target +window. + +The bezier function is defined as:- + +void +DrawBezier (gdouble (*points)[2], gint np, gdouble mid, gint depth) +{ +... +} + +Points an array of pairs of doubles that define the control points +np is the number of points. Mid is always starts as 0.5 - and depth +defines how deep the recursion should go when calculating the line points. + +The function should call fp_pnt_add() when a point on the curve has been +calculated. + +If anyone would like to produce a better/faster function then you +should be able to replace the DrawBezier function. (Only the first two args +are really needed). + +The algorithm the current code is based on was obtained by looking +at the many many examples out on the web. +(Bezier drawing seems to be topic of the year for computer degrees +and people learning java!!!) + diff --git a/plug-ins/gfig/gfig-arc.c b/plug-ins/gfig/gfig-arc.c new file mode 100644 index 0000000..5e8be02 --- /dev/null +++ b/plug-ins/gfig/gfig-arc.c @@ -0,0 +1,735 @@ +/* + * Copyright (C) 1995 Spencer Kimball and Peter Mattis + * + * This is a plug-in for GIMP. + * + * Generates images containing vector type drawings. + * + * Copyright (C) 1997 Andy Thomas alt@picnic.demon.co.uk + * + * This program is free software: you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 3 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The author + can not be held liable for any damage caused by proper or + improper use of this program. + + +--- Introduction + +The GIMPressionist is a plug-in for the GNU Image Manipulation Program, +a.k.a. GIMP. It can be used to create natural looking painting effects +and similar. It can also be run in a primitive "standalone" mode. + +The current version is still a bit shaky, and is to be considered beta +software. I'll do some serious testing, hopefully across a few more +platforms, as soon as I can. + +The official Web-page is http://www.prosalg.no/~vidar/gimpressionist/ and +will always contain a link to the latest released version. + + +--- Compiling / Installing + +To compile (hopefully): + make + +If you want to compile for GTK-1.1 and GIMP-1.1 instead, you will have +to change the two variable at the top of Makefile. Possibly you would +want to edit DEFAULTPATH as well, but that's not critical. + +To install plug-in and accompanying files: + make install + +The plug-in installs itself under $HOME/.gimp/plug-ins/ and copies a +couple of files into the directory $HOME/.gimp/gimpressionist/. The +subdirectories 'Brushes', 'Paper' and 'Presets' will be created during +"make install", and a few files will be added; As a minimum, +'defaultbrush.pgm' and 'defaultpaper.pgm' under their respective +directories. These are vanilla .PGM files, which could be edited (and +created) with any decent program - like GIMP! :-) + + +--- Standalone + +As of version 0.99 and later, the GIMPressionist can also be run +separately from GIMP. This is primarily intended for debugging +purposes, though, as it still needs GIMP libraries to compile. In your +shell, type: + gimpressionist somefile.ppm + +The image specified must be a valid PPM file. No other formats are +supported, and probably never will. + +If you click "OK", the PPM will be replaced with the "repainted" version. +If you "Cancel", nothing will be done to the file. + + +--- File Formats + +The "normal" brushes are simply grayscale PGM files, which can be created +with almost any program, including xv and of course GIMP. A number of +brushes is included, so I guess a more in-depth explanation is not +necessary. And, for those who might want to try it, GIMPressionist can +also read GBR files, which is GIMP's native brush format. (You still +need to copy them to the GIMPressionist's brush-directory, though. This +will probably be fixed sometimes.) + +Version 0.99.4 introduced the concept of using "colored" brushes (although +"pre-rendered" usually is more correct). The brushes' file format is a +plain PPM file, but the layout is somewhat special (and kinda hard to +explain); + +- The Red channel contains a shading map of the brush in question. Often + it resembles the overall image more or less completely. + +- The Green channel contains a high-light map. This is a pre-defined + image of the shiny parts of the brush. (Ordinary grayscale brushes + have this calculated automatically with a rough emboss-ish algorithm.) + +- The Blue channel functions as a brush mask. When applying a brush + stroke to the image, all areas colored blue in the file are first + "blacked out" of the image. + + +--- Feedback + +If you have any comments, criticism, ideas for improvement or new +features, or if you run into problems of any sort, let me know, so that I +can (try to) fix it for the next release! (And, if you find platform- +dependent bugs, please try to fix them and send me a patch!) + +I'm also welcoming contributions in the form of brushes or textures! For +this program to be valuable, it needs them... Bad!

The name "GFlare" is short for +"Gradient Flare". It renders lense flare effect using custom +gradients. The basic idea is suggested by Marcelo Malheiros, +originally based on a 3DStudio MAX plug-in called LenZFX: + http://www.digimation.com/techsupp/lzfxfeat.htm + +INSTALL: + +1) Edit Makefile, if needed. + +2) Type "make install". + +3) Type "make install-data" if needed. (It copies sample gradients and + gflares under ~/.gimp) + +3) Add new entry to ~/.gimp/gimprc as + (gflare-path "${gimp_dir}/gflares:${gimp_data_dir}/gflares") + +3) Run GIMP. The menu path is /Filters/Effects/GFlare. + + +HOW TO USE IT: + + The document is not yet done. Try and see. + + Main Dialog: + - Preview + click on it changes the position of GFlare + - Settings page + - Center, Radius (pixel), Rotation (degree), Hue Rotation (degree) + - Vector Angle (degree) and Vector Length (percentage to Radius) + - adaptive supersampling ... same as "Blend tool" + - Selector page + - ListBox + - New, Edit, Copy, Delete buttons. Edit button invokes GFlare Editor. + + GFlare Editor: + - General page: + - Glow page: + - Rays page: + - Second Flares page: + + WARNING: This plug-in is in development stage, and the code is very +alpha. The GFlare datafile format may be changed in future version. + + Suggestions and ideas for user interface, flare algorithm, etc. are +very welcome. + + +KNOWN BUGS: + + There are still lots of bugs, of course. ;-) + They seem related to GTK, and I don't know exactly how I can fix them. + + * It warns at startup as: + ** WARNING **: file gdkwindow.c: line 422 (gdk_window_move_resize): "window != NULL" + If you are annoyed, accompanying "gtkviewport.c.patch" will shut up + the warning. + * Edit button remains prelighted when GFlare Editor dialog is done. + * Dialogs are not shown quickly at startup. + * Sometimes note tab labels are disappeared. + * Sometimes it crashes, but I don't know yet why it happens. + +TODO: + * Random hue scattering for Second Flares. + * Improve internal gradients. + * Currently number of Second Flares is fixed(30). + * Change opacity for one second flare dynamically, in inverse + proportion to the size of it. + * Reduce dialog size + * Add tweak ability "How to combine Glow, Rays, Second Flares in + what order" + + +CREDITS: + + Marcelo Marheiros and Federico Mena Quintero suggested a lot of +ideas.

They are also the basis of fractal image compression. + +For a brief introduction to IFS's see Foley and van Dam, et +al,. _Computer Graphics, Principles and Practice_, 2nd Ed., +(Addison Wesley, 1990). + +The standard references in the field are Michael Barnsley's books (though +I haven't looked at them yet): + +M. Barnsley, _Fractals Everywhere_, Academic Press Inc., 1988. +M. Barnsley and L. Hurd, _Fractal Image Compression_, Jones and +Bartlett. + +Briefly, you take a point and repeatedly apply one of a set of +transformations to it, choosing randomly between them, and plot the +point at each step. An interesting result (the Collage Theorem) says +that if you can find a set of transformations that break up an image +into smaller copies of itself, then the resulting fractal exactly +reproduces the original image. For example, here is a classic image +of a leaf and the same image with the four component transforms +colored distinctively. + +But the best way to appreciate this may to install this program and +try it out. I've extended the basic concept as found in +Foley and van Dam to include transformations in color space as +well as in real space. + +Installation +------------ +The included Makefile should work with minor modifications on most +systems if you have installed Gimp normally. Put the resulting binary +in ~/.gimp/plug-ins or the system-wide plug-ins directory. + +The included files gtkaspectframe.c/.h implement a modified frame +widget that guarantees that the aspect ratio of the child widget +remains constant when the parent is resized. It's sort of specialized, +but if you think it would be useful for other purposes, let me know +and I'll lobby for its inclusion in the standard gtk. + +Use +--- +The interface is somewhat complex and it may take you a little while +to get the hang of it. (There are 19 parameters for each +transformation in your fractal, after all). The best way to learn is +probably to start by making small changes, and seeing what they +do. Click on the transformations (represented by polygons) in the +design window to manipulate them interactively. + +Button-1: rotate/scale +Button-2: distort +Button-3: move + +If you hold down shift while clicking, you can select multiple polygons +to apply the transformation to. + +Try not to click too near the center of a polygon, as this will +amplify your actions. + +Note that if you render onto an image with an alpha channel, the +background will be transparent (very useful for compositing several +fractals), otherwise the background will be the current background. + +There are tutorials and some example images at: + + http://www.gtk.org/~otaylor/IfsCompose/ifs_tutorial/tutorial.html + http://tigert.gimp.org/gimp/ifs-compose/ + + +Have fun! + +Owen Taylor diff --git a/plug-ins/ifs-compose/ifs-compose-storage.c b/plug-ins/ifs-compose/ifs-compose-storage.c new file mode 100644 index 0000000..24705be --- /dev/null +++ b/plug-ins/ifs-compose/ifs-compose-storage.c @@ -0,0 +1,551 @@ +/* GIMP - The GNU Image Manipulation Program + * Copyright (C) 1995 Spencer Kimball and Peter Mattis + * + * IfsCompose is a interface for creating IFS fractals by + * direct manipulation. + * Copyright (C) 1997 Owen Taylor + * + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 3 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTBILITY or FITNESS FOR A PARTICULAR PURPOSE.

It will also make sure that the displays are flushed +on completion if the plug-in was run interactively. + +When registering the plug-in, you do not need to worry about +specifying the run_type parameter. + +A typical gimpfu plug-in would look like this: + from gimpfu import * + + def plugin_func(image, drawable, args): + # do what plugins do best + register( + "plugin_func", + "blurb", + "help message", + "author", + "copyright", + "year", + "My plug-in", + "*", + [ + (PF_IMAGE, "image", "Input image", None), + (PF_DRAWABLE, "drawable", "Input drawable", None), + (PF_STRING, "arg", "The argument", "default-value") + ], + [], + plugin_func, menu="/Somewhere") + main() + +The call to "from gimpfu import *" will import all the gimp constants +into the plug-in namespace, and also import the symbols gimp, pdb, +register and main. This should be just about all any plug-in needs. + +You can use any of the PF_* constants below as parameter types, and an +appropriate user interface element will be displayed when the plug-in +is run in interactive mode. Note that the the PF_SPINNER and +PF_SLIDER types expect a fifth element in their description tuple -- a +3-tuple of the form (lower,upper,step), which defines the limits for +the slider or spinner. + +If want to localize your plug-in, add an optional domain parameter to +the register call.

These functions take use to callbacks -- one +is a constraint function, and the other is the callback object.

2002 Manuel Heras-Gilsanz (manuel@heras-gilsanz.com) + +This software is subject to the license terms contained in the +LICENSE file. + +Changelog: +1.1 (Sept. 2002) Updated to tinyscheme 1.31 +1.0 (April 2002) First released version + + +WHAT IS TSX? + +TinyScheme Extensions is a set of dynamic libraries incorporating +additional funcionality to TinyScheme, a lightweight +implementation of the Scheme programming language. TinyScheme +(http://tinyscheme.sourceforge.net) is maintained by D. Souflis +(dsouflis@acm.org), and is based on MiniSCHEME version 0.85k4. + +Scheme is a very nice and powerful programming language, but the +basic language is very minimalistic in terms of library functions; +only basic file input / output functionality is specified. +Different implementations of the language (MIT Scheme, GUILE, +Bigloo...) provide their own extension libraries. TSX attempts to +provide commonly needed functions at a small cost in terms of +additional program footprint. The library is modularized, so that +it is possible (and easy!) to select desired functionality via +#defines in tsx.h. + + +INSTALLATION + +TSX has been tested on GNU/Linux 2.4.2 with gcc 2.96 and +libc-2.2.2, with TinyScheme 1.31. + +To install, copy the distribution file to the directory +where TinyScheme is installed (and where scheme.h lies), +and run make. If building succeeds, a file called tsx.so +should be created. This file can be loaded as a TinyScheme +extension with + + (load-extension "tsx-1.0/tsx") + +After loading TSX, you can make use of its functions. +To reduce footprint, you can choose the functionality which +will be included. To do so, have a look at tsx.h and +comment the #defines for unneeded modules. + +If you get compiler errors, make sure you have enabled +dynamic modules in your tinyscheme runtime (define USE_DL +somewhere near the top in scheme.h). + + +SAMPLE APPLICATIONS + +Three sample applications are distributed with TSX 1.0. +The code is not particularly elegant, nor written in proper +functional style, but is provided for illustration of the +implemented calls. + +-smtp.scm + Sends an email to the user getting the username from + the USER shell variable, connecting to the SMTP port + on the local machine. + +-listhome.scm + Provides a list of all the files on the user's home + directory (obtained with the HOME environment variable). + +-srepl.scm + Provides a socket-based read-eval-print-loop. It listens + for connections on the 9000 port of the local machines, + and executes the commands received. To test it, run + + telnet localhost 9000 + + after starting the sample application, and type Scheme + expressions. You will get the evaluations. To exit the + session, type "quit" and TinyScheme will exit, closing + the socket. The output of some functions will not + be the same as you would obtain on TinyScheme's + "command line", because standard output is not + redirected to the socket, but most commands work ok. + +You should copy these applications to the directory where +TinyScheme is installed (i.e., where the "scheme" binary +file resides), and can be run with: + + ./scheme listhome.scm + ./scheme smtp.scm + ./scheme srepl.scm + + +TSX FUNCTIONS + +The extension functions implemented by TinyScheme Extensions are +documented in the file "tsx-functions.txt". + +END diff --git a/plug-ins/script-fu/ftx/ftx-functions.txt b/plug-ins/script-fu/ftx/ftx-functions.txt new file mode 100644 index 0000000..5365bc5 --- /dev/null +++ b/plug-ins/script-fu/ftx/ftx-functions.txt @@ -0,0 +1,119 @@ +File and Time Extensions for TinyScheme (FTX) 1.0 [August, 2004] + +Based on the TinyScheme Extensions (TSX) 1.1 [September, 2002] +(c) 2002 Manuel Heras-Gilsanz (manuel@heras-gilsanz.com) + +This software is subject to the license terms contained in the +LICENSE file. + + +TSX FUNCTIONS + +TSX incorporates the following functions: + +*File system (included if HAVE_FILESYSTEM is defined in tsx.h) + +Scheme already defines functions to read and write files.

It should be used in scripts which build file +names that include one or more directories to keep the scripts +portable to different operating systems. + +(file-exists? filename) + filename: string + + This function returns #t if the indicated file exists, and + #f if it does not exist or if it is not accessible to the + requesting user. Accessibility is based on the real user + and group ID rather than the effective user ID and group ID. + +(file-type filename) + filename: string + + This function returns a value based on the file type. It + returns FILE_TYPE_FILE (1) for regular files, FILE_TYPE_DIR + (2) for directories, and FILE_TYPE_LINK (3) for symbolic + links. The value FILE_TYPE_OTHER (0) is returned if the file + is of some other type, does not exist, or if the user does + not have sufficient privileges to allow the file type to be + determined. + +(file-size filename) + filename: string + + This function returns the size (in bytes) of the + indicated file, or #f if the file does not exists or + is not accessible to the requesting user. + +(file-delete filename) + filename: string + + Removes the specified file. It returns #t if the operation + succeeds, or #f otherwise (e.g., because the file is + read-only, or because the file does not exist). + +(dir-open-stream path) + path: string + + Opens a "directory stream" on the provided directory path. + This stream will provide all the files within the directory, + using the function read-dir-entry. The stream should be closed + at the end with dir-close-stream. + +(dir-read-entry dirstream) + dirstream: directory stream, obtained with dir-open-stream. + + It returns the name of the following directory entry, or eof + if all the entries were provided. Check the return value with + with eof-object?. + +(dir-rewind dirstream) + dirstream: directory stream, obtained with dir-open-stream. + + Resets the given directory stream. The next call to dir-read-entry + will return the first entry again. It returns #t if the operation + succeeds, or #f otherwise (ie. dirstream not valid).. + +(dir-close-stream dirstream) + dirstream: directory stream, obtained with dir-open-stream. + + Close directory stream. No further calls to read-dir-entry should + be performed. + +(dir-make dirname . mode) + dirname: string + mode: integer representing permissions + + Create the directory specified, setting the directory permissions based + upon the optional mode argument (taking into account the current + umask). If no mode is specified then use the default (umask) + permissions.

Lots of bugfixes have accumulated in my email, so + I had to start using them. In this version, Keenan Pepper has submitted + a bugfix for the string comparison library procedure, Wouter Boeke + modified some code that was casting to the wrong type and crashed on + some machines, "SheppardCo" submitted a replacement "modulo" code and + Scott Fenton submitted lots of corrections that shut up some compiler + warnings. Brian Maher submitted instructions on how to build on OS-X. + I have to dig deeper into my mailbox and find earlier emails, too. + +Version 1.33 + Charles Hayden fixed a nasty GC bug of the new stack frame, while in + the process of porting TinyScheme to C++. He also submitted other + changes, and other people also had comments or requests, but the GC + bug was so important that this version is put through the door to + correct it. + +Version 1.32 + Stephen Gildea put some quality time on TinyScheme again, and made + a whole lot of changes to the interpreter that made it noticeably + faster. + +Version 1.31 + Patches to the hastily-done version 1.30. Stephen Gildea fixed + some things done wrongly, and Richard Russo fixed the makefile + for building on Windows. Property lists (heritage from MiniScheme) + are now optional and have disappeared from the interface. They + should be considered as deprecated. + +Version 1.30 + After many months, I followed Preston Bannister's advice of + using macros and a single source text to keep the enums and the + dispatch table in sync, and I used his contributed "opdefines.h". + Timothy Downs contributed a helpful function, "scheme_call". + Stephen Gildea contributed new versions of the makefile and + practically all other sources. He created a built-in STRING-APPEND, + and fixed a lot of other bugs. + Ruhi Bloodworth reported fixes necessary for OS X and a small + bug in dynload.c. + +Version 1.29 + The previous version contained a lot of corrections, but there + were a lot more that still wait on a sheet of paper lost in a + carton someplace after my house move... Manuel Heras-Gilsanz + noticed this and resent his own contribution, which relies on + another bugfix that v.1.28 was missing: a problem with string + output, that this version fixes. I hope other people will take + the time to resend their contributions, if they didn't make it + to v.1.28. + +Version 1.28 + Many people have contacted me with bugfixes or remarks in + the three months I was inactive. A lot of them spotted that + scheme_deinit crashed while reporting gc results. They suggested + that sc->outport be set to NIL in scheme_deinit, which I did. + Dennis Taylor remarked that OP_VALUEPRINT reset sc->value instead + of preserving it. He submitted a modification which I adopted + partially. David Hovemeyer sent me many little changes, that you + will find in version 1.28, and Partice Stoessel modified the + float reader to conform to R5RS. + +Version 1.27 + Version 1.27 is the successor of 1.25. Bug fixes only, but I had to + release them so that everybody can profit. 'Backchar' tried to write + back to the string, which obviously didn't work for const strings. + 'Substring' didn't check for crossed start and end indices. Defines + changed to restore the ability to compile under MSVC. + +Version 1.26 + Version 1.26 was never released. I changed a lot of things, in fact + too much, even the garbage collector, and hell broke loose. I'll + try a more gradual approach next time. + +Version 1.25 + Types have been homogenized to be able to accommodate a different + representation. Plus, promises are no longer closures. Unfortunately, + I discovered that continuations and force/delay do not pass the SCM + test (and never did)... However, on the bright side, what little + modifications I did had a large impact on the footprint: + USE_NO_FEATURES now produces an object file of 63960 bytes on Linux! + +Version 1.24 + SCM tests now pass again after change in atom2str. + +Version 1.23 + Finally I managed to mess it up with my version control. Version + 1.22 actually lacked some of the things I have been fixing in the + meantime. This should be considered as a complete replacement for + 1.22. + +Version 1.22 + The new ports had a bug in LOAD. MK_CLOSURE is introduced. + Shawn Wagner inquired about string->number and number->string. + I added string->atom and atom->string and defined the number + functions from them. Doing that, I fixed WRITE applied to symbols + (it didn't quote them). Unfortunately, minimum build is now + slightly larger than 64k... I postpone action because Jason's idea + might solve it elegantly. + +Version 1.21 + Jason Felice submitted a radically different datatype representation + which he had implemented. While discussing its pros and cons, it + became apparent that the current implementation of ports suffered + from a grave fault: ports were not garbage-collected. I changed the + ports to be heap-allocated, which enabled the use of string ports + for loading. Jason also fixed errors in the garbage collection of + vectors. USE_VERBATIM is gone. "ssp_compiler.c" has a better solution + on HTML generation. A bug involving backslash notation in strings + has been fixed. '-c' flag now executes next argument as a stream of + Scheme commands. Foreign functions are now also heap allocated, + and scheme_define is used to define everything. + +Version 1.20 + Tracing has been added. The toplevel loop has been slightly + rearranged. Backquote reading for vector templates has been + sanitized. Symbol interning is now correct. Arithmetic functions + have been corrected. APPLY, MAP, FOR-EACH, numeric comparison + functions fixed. String reader/writer understands \xAA notation. + +Version 1.19 + Carriage Return now delimits identifiers. DOS-formatted Scheme files + can be used by Unix. Random number generator added to library. + Fixed some glitches of the new type-checking scheme. Fixed erroneous + (append '() 'a) behavior. Will continue with r4rstest.scm to + fix errors. + +Version 1.18 + The FFI has been extended. USE_VERBOSE_GC has gone. Anyone wanting + the same functionality can put (gcverbose #t) in init.scm. + print-width was removed, along with three corresponding op-codes. + Extended character constants with ASCII names were added. + mk_counted_string paves the way for full support of binary strings. + As much as possible of the type-checking chores were delegated + to the inner loop, thus reducing the code size to less than 4200 loc! + +Version 1.17 + Dynamically-loaded extensions are more fully integrated. + TinyScheme is now distributed under the BSD open-source license. + +Version 1.16 + Dynamically-loaded extensions introduced (USE_DL). + Santeri Paavolainen found a race condition: When a cons is executed, + and each of the two arguments is a constructing function, GC could + happen before all arguments are evaluated and cons() is called, and + the evaluated arguments would all be reclaimed! + Fortunately, such a case was rare in the code, although it is + a pitfall in new code and code in foreign functions.

"Safe if used as prescribed" + -- Philip K. Dick, "Ubik" + +This software is open source, covered by a BSD-style license. +Please read accompanying file COPYING. +------------------------------------------------------------------------------- + + This Scheme interpreter is based on MiniSCHEME version 0.85k4 + (see miniscm.tar.gz in the Scheme Repository) + Original credits in file MiniSCHEMETribute.txt. + + D. Souflis (dsouflis@acm.org) + +------------------------------------------------------------------------------- + What is TinyScheme? + ------------------- + + TinyScheme is a lightweight Scheme interpreter that implements as large + a subset of R5RS as was possible without getting very large and + complicated. It is meant to be used as an embedded scripting interpreter + for other programs. As such, it does not offer IDEs or extensive toolkits + although it does sport a small top-level loop, included conditionally. + A lot of functionality in TinyScheme is included conditionally, to allow + developers freedom in balancing features and footprint. + + As an embedded interpreter, it allows multiple interpreter states to + coexist in the same program, without any interference between them. + Programmatically, foreign functions in C can be added and values + can be defined in the Scheme environment. Being a quite small program, + it is easy to comprehend, get to grips with, and use. + + Known bugs + ---------- + + TinyScheme is known to misbehave when memory is exhausted. + + + Things that keep missing, or that need fixing + --------------------------------------------- + + There are no hygienic macros. No rational or + complex numbers. No unwind-protect and call-with-values. + + Maybe (a subset of) SLIB will work with TinySCHEME... + + Decent debugging facilities are missing. Only tracing is supported + natively. + + + Scheme Reference + ---------------- + + If something seems to be missing, please refer to the code and + "init.scm", since some are library functions. Refer to the MiniSCHEME + readme as a last resort. + + Environments + (interaction-environment) + See R5RS. In TinySCHEME, immutable list of association lists. + + (current-environment) + The environment in effect at the time of the call. An example of its + use and its utility can be found in the sample code that implements + packages in "init.scm": + + (macro (package form) + `(apply (lambda () + ,@(cdr form) + (current-environment)))) + + The environment containing the (local) definitions inside the closure + is returned as an immutable value. + + (defined? ) (defined? ) + Checks whether the given symbol is defined in the current (or given) + environment. + + Symbols + (gensym) + Returns a new interned symbol each time. Will probably move to the + library when string->symbol is implemented. + + Directives + (gc) + Performs garbage collection immediately. + + (gcverbose) (gcverbose ) + The argument (defaulting to #t) controls whether GC produces + visible outcome. + + (quit) (quit ) + Stops the interpreter and sets the 'retcode' internal field (defaults + to 0). When standalone, 'retcode' is returned as exit code to the OS. + + (tracing ) + 1, turns on tracing. 0 turns it off.

Handy for imperative programs. + + (new-segment ) + Allocates more memory segments. + + defined? + See "Environments" + + (get-closure-code ) + Gets the code as scheme data. + + (make-closure ) + Makes a new closure in the given environment. + + Obsolete procedures + (print-width ) + + Programmer's Reference + ---------------------- + + The interpreter state is initialized with "scheme_init". + Custom memory allocation routines can be installed with an alternate + initialization function: "scheme_init_custom_alloc". + Files can be loaded with "scheme_load_file". Strings containing Scheme + code can be loaded with "scheme_load_string". It is a good idea to + "scheme_load" init.scm before anything else. + + External data for keeping external state (of use to foreign functions) + can be installed with "scheme_set_external_data". + Foreign functions are installed with "assign_foreign". Additional + definitions can be added to the interpreter state, with "scheme_define" + (this is the way HTTP header data and HTML form data are passed to the + Scheme script in the Altera SQL Server). If you wish to define the + foreign function in a specific environment (to enhance modularity), + use "assign_foreign_env". + + The procedure "scheme_apply0" has been added with persistent scripts in + mind. Persistent scripts are loaded once, and every time they are needed + to produce HTTP output, appropriate data are passed through global + definitions and function "main" is called to do the job. One could + add easily "scheme_apply1" etc. + + The interpreter state should be deinitialized with "scheme_deinit". + + DLLs containing foreign functions should define a function named + init_. E.g. foo.dll should define init_foo, and bar.so + should define init_bar. This function should assign_foreign any foreign + function contained in the DLL. + + The first dynamically loaded extension available for TinyScheme is + a regular expression library. Although it's by no means an + established standard, this library is supposed to be installed in + a directory mirroring its name under the TinyScheme location. + + + Foreign Functions + ----------------- + + The user can add foreign functions in C. For example, a function + that squares its argument: + + pointer square(scheme *sc, pointer args) { + if(args!=sc->NIL) { + if(sc->isnumber(sc->pair_car(args))) { + double v=sc->rvalue(sc->pair_car(args)); + return sc->mk_real(sc,v*v); + } + } + return sc->NIL; + } + + Foreign functions are now defined as closures: + + sc->interface->scheme_define( + sc, + sc->global_env, + sc->interface->mk_symbol(sc,"square"), + sc->interface->mk_foreign_func(sc, square)); + + + Foreign functions can use the external data in the "scheme" struct + to implement any kind of external state. + + External data are set with the following function: + void scheme_set_external_data(scheme *sc, void *p); + + As of v.1.17, the canonical way for a foreign function in a DLL to + manipulate Scheme data is using the function pointers in sc->interface. + + Standalone + ---------- + + Usage: tinyscheme -? + or: tinyscheme [ ...] + followed by + -1 [ ...] + -c [ ...] + assuming that the executable is named tinyscheme. + + Use - in the place of a filename to denote stdin. + The -1 flag is meant for #! usage in shell scripts. If you specify + #! /somewhere/tinyscheme -1 + then tinyscheme will be called to process the file. For example, the + following script echoes the Scheme list of its arguments. + + #! /somewhere/tinyscheme -1 + (display *args*) + + The -c flag permits execution of arbitrary Scheme code. + + + Error Handling + -------------- + + Errors are recovered from without damage. The user can install his + own handler for system errors, by defining *error-hook*. Defining + to '() gives the default behavior, which is equivalent to "error". + USE_ERROR_HOOK must be defined. + + A simple exception handling mechanism can be found in "init.scm". + A new syntactic form is introduced: + + (catch + ... ) + + "Catch" establishes a scope spanning multiple call-frames + until another "catch" is encountered. + + Exceptions are thrown with: + + (throw "message") + + If used outside a (catch ...), reverts to (error "message"). + + Example of use: + + (define (foo x) (write x) (newline) (/ x 0)) + + (catch (begin (display "Error!\n") 0) + (write "Before foo ... ") + (foo 5) + (write "After foo")) + + The exception mechanism can be used even by system errors, by + + (define *error-hook* throw) + + which makes use of the error hook described above. + + If necessary, the user can devise his own exception mechanism with + tagged exceptions etc. + + + Reader extensions + ----------------- + + When encountering an unknown character after '#', the user-specified + procedure *sharp-hook* (if any), is called to read the expression. + This can be used to extend the reader to handle user-defined constants + or whatever. It should be a procedure without arguments, reading from + the current input port (which will be the load-port). + + + Colon Qualifiers - Packages + --------------------------- + + When USE_COLON_HOOK=1: + The lexer now recognizes the construction :: and + transforms it in the following manner (T is the transformation function): + + T(::) = (*colon-hook* 'T() ) + + where is a symbol not containing any double-colons. + + As the definition is recursive, qualifiers can be nested. + The user can define his own *colon-hook*, to handle qualified names. + By default, "init.scm" defines *colon-hook* as EVAL. Consequently, + the qualifier must denote a Scheme environment, such as one returned + by (interaction-environment). "Init.scm" defines a new syntantic form, + PACKAGE, as a simple example. It is used like this: + + (define toto + (package + (define foo 1) + (define bar +))) + + foo ==> Error, "foo" undefined + (eval 'foo) ==> Error, "foo" undefined + (eval 'foo toto) ==> 1 + toto::foo ==> 1 + ((eval 'bar toto) 2 (eval 'foo toto)) ==> 3 + (toto::bar 2 toto::foo) ==> 3 + (eval (bar 2 foo) toto) ==> 3 + + If the user installs another package infrastructure, he must define + a new 'package' procedure or macro to retain compatibility with supplied + code. + + Note: Older versions used ':' as a qualifier. Unfortunately, the use + of ':' as a pseudo-qualifier in existing code (i.e. SLIB) essentially + precludes its use as a real qualifier. + + + + + + + + diff --git a/plug-ins/script-fu/tinyscheme/MiniSCHEMETribute.txt b/plug-ins/script-fu/tinyscheme/MiniSCHEMETribute.txt new file mode 100644 index 0000000..185f0ec --- /dev/null +++ b/plug-ins/script-fu/tinyscheme/MiniSCHEMETribute.txt @@ -0,0 +1,88 @@ + TinyScheme would not exist if it wasn't for MiniScheme.

The debugging version is + a special version capable of capturing the TWAIN datasource data to + a file for later processing. This feature can be used to create a data + dump that can be sent to me if for some reason the plug-in fails for + your TWAIN datasource. The function of the plug-in is controlled by + the name of the executable file. The plug-in should be placed in your + plug-ins directory and named as follows: + +twain.exe - This is the standard (non-debugging) version. This file will + not behave differently if renamed. This version is intended to be used + unless your TWAIN datasource has some problem. + +gtwain.exe - This is the debugging version of the program shipped along. + If this program is used as named, it will behave the same as "twain.exe" + except that the file C:\twain.log will be written. This file is a text + file with very little information available for debugging. + +dtwain.exe - Renaming "gtwain.exe" to "dtwain.exe" in your plug-ins directory + will change the behavior of the plug-in. The menu option will be registered + as "TWAIN Acquire (Dump)..." and will cause the TWAIN acquire operation to + be dumped to the file "C:\twaincap.bin". This file contains all of the data + necessary to recreate the capture on another system (such as my machine). The + image will not be displayed, as it might cause the plug-in to crash making + the data useless. Instead, a message will be displayed that the image + information was dumped to a file. + +rtwain.exe - Renaming "gtwain.exe" to "rtwain.exe" in your plug-ins directory + will change the behavior of the plug-in. The menu option will be registered + as "TWAIN Acquire (Read)..." and will cause the TWAIN acquire operation to + read a previously dumped (using dtwain.exe) TWAIN acquire from + "C:\twaincap.bin". + +If you find that you are unable to capture data from you datasource (the plug-in +crashes or the image is wrong), please capture data using the following steps: + +1) Copy gtwain.exe to your plug-ins directory as "dtwain.exe". +2) Run GIMP. +3) Choose Xtns->TWAIN Acquire (Dump)... +4) Choose the datasource settings that are causing problems. +5) Choose a *SMALL* sample image. +6) Zip up "C:\twaincap.bin" and "C:\twain.log" and send them to me. diff --git a/plug-ins/twain/gimp-twain.png b/plug-ins/twain/gimp-twain.png new file mode 100644 index 0000000..25ff3f3 Binary files /dev/null and b/plug-ins/twain/gimp-twain.png differ diff --git a/plug-ins/twain/tw_dump.c b/plug-ins/twain/tw_dump.c new file mode 100644 index 0000000..b75bc8c --- /dev/null +++ b/plug-ins/twain/tw_dump.c @@ -0,0 +1,273 @@ +/* + * TWAIN Plug-in + * Copyright (C) 1999 Craig Setera + * Craig Setera + * 03/31/1999 + * + * Updated for Mac OS X support + * Brion Vibber + * 07/22/2004 + * + * This program is free software: you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 3 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
