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! All contributions will +be properly credited, of course. + +Good luck and happy painting! + +Vidar Madsen <vidar@prosalg.no> |
