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 <Image>/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. Very Thanks!! + + Marcelo made gradients whose names end with _1, _2, etc. The +gradients whose names end with _101, _102 etc. are mine. + + Quartic did awful Gradient Editor, and gradients PDB procedures. + + A fair proportion of this code was taken from: + + GIMP - The GNU Image Manipulation Program + Copyright (C) 1995 Spencer Kimball and Peter Mattis + + Gradient editor module copyight (C) 1996-1997 Federico Mena Quintero + federico@nuclecu.unam.mx |
