2003-07-22 Michael Natterer <mitch@gimp.org> * app/core/gimpgradient.[ch]: added "gboolean reverse" to gimp_gradient_get_color_at() so all gradients can be used reversed. * app/core/gimpdrawable-blend.[ch] (gimp_drawable_blend) * app/core/gimppalette-import.[ch] (gimp_palette_import_from_gradient): added "gboolean reverse". * app/paint/paint-enums.[ch]: removed enum GimpGradientRepeatMode since it is identical to GimpRepeatMode, except for the now obsolete ONCE_BACKWARD value. * app/paint/gimppaintcore.[ch]: removed gimp_paint_core_get_color_from_gradient()... * app/paint/gimppaintoptions.[ch]: ...and added gimp_paint_options_get_gradient_color(), which is much more general. Added a "reverse" property to GimpGradientOptions and changed the type of the "repeat" property to GimpRepeatMode. * app/paint/gimppaintbrush.c: use gimp_paint_options_get_gradient_color(). * app/tools/gimpblendoptions.[ch]: removed the "repeat" property since it is in the parent class now. * app/gui/gradient-select.c * app/gui/palette-import-dialog.c * app/widgets/gimpgradienteditor.c * app/tools/gimpblendtool.c * tools/pdbgen/pdb/gradients.pdb * tools/pdbgen/pdb/misc_tools.pdb: changed accordingly. * app/tools/gimppaintoptions-gui.c: added a "Reverse" toggle right of the gradient preview. * app/widgets/gimppreviewrenderergradient.[ch]: added "gboolean reverse" member and gimp_preview_renderer_gradient_set_reverse() API. * tools/pdbgen/pdb/paint_tools.pdb: fixed the paintbrush invoker to set GimpPaintOption's "use-fade" and "use-gradient" properties correctly. * app/pdb/gradients_cmds.c * app/pdb/misc_tools_cmds.c * app/pdb/paint_tools_cmds.c * libgimp/gimpenums.h * libgimp/gimpmisctools_pdb.[ch] * plug-ins/pygimp/gimpenums.py * plug-ins/script-fu/script-fu-constants.c * tools/pdbgen/enums.pl: regenerated. * libgimp/gimpcompat.h * plug-ins/script-fu/siod-wrapper.c: removed GimpGradientPaintMode here too since it was only exported accidentially (it's not used by any external API). * plug-ins/script-fu/scripts/3dTruchet.scm * plug-ins/script-fu/scripts/alien-glow-arrow.scm * plug-ins/script-fu/scripts/alien-glow-bar.scm * plug-ins/script-fu/scripts/alien-glow-bullet.scm * plug-ins/script-fu/scripts/alien-glow-button.scm * plug-ins/script-fu/scripts/alien-glow-logo.scm * plug-ins/script-fu/scripts/basic1-logo.scm * plug-ins/script-fu/scripts/basic2-logo.scm * plug-ins/script-fu/scripts/beveled-button.scm * plug-ins/script-fu/scripts/blended-logo.scm * plug-ins/script-fu/scripts/burn-in-anim.scm * plug-ins/script-fu/scripts/coffee.scm * plug-ins/script-fu/scripts/comic-logo.scm * plug-ins/script-fu/scripts/coolmetal-logo.scm * plug-ins/script-fu/scripts/glossy.scm * plug-ins/script-fu/scripts/gradient-bevel-logo.scm * plug-ins/script-fu/scripts/gradient-example.scm * plug-ins/script-fu/scripts/pupi-button.scm * plug-ins/script-fu/scripts/rendermap.scm * plug-ins/script-fu/scripts/sphere.scm * plug-ins/script-fu/scripts/starscape-logo.scm * plug-ins/script-fu/scripts/test-sphere.scm * plug-ins/script-fu/scripts/textured-logo.scm * plug-ins/script-fu/scripts/title-header.scm * plug-ins/script-fu/scripts/weave.scm: pass "reverse" to gimp_blend(). Pass FALSE in most cases and added script parameters were it makes sense.
