2005-02-15 Sven Neumann <sven@gimp.org> * app/core/gimpimagemap.[ch]: changed GimpImageMapApplyFunc to be compatible with PixelProcessorFunc. * app/base/color-balance.[ch] * app/base/colorize.[ch] * app/base/gimplut.[ch] * app/base/hue-saturation.[ch] * app/base/threshold.[ch]: removed wrappers that used to shift parameters around to match GimpImageMapApplyFunc and PixelProcessorFunc signatures. * app/tools/gimpbrightnesscontrasttool.c * app/tools/gimpcolorbalancetool.c * app/tools/gimpcurvestool.c * app/tools/gimplevelstool.c * app/tools/gimpposterizetool.c * app/tools/gimpthresholdtool.c: changed accordingly. * tools/pdbgen/pdb/color.pdb: use pixel_region_process_parallel() for all color operations. * app/pdb/color_cmds.c: regenerated.
