Color correction tool chopping: 2002-08-26 Michael Natterer <mitch@gimp.org> Color correction tool chopping: * app/Makefile.am * app/image_map.[ch]: removed... * app/core/Makefile.am * app/core/core-types.h * app/core/gimpimagemap.[ch]: ...and added here as object. * app/base/Makefile.am * app/base/base-types.h * app/base/color-balance.[ch] * app/base/curves.[ch] * app/base/hue-saturation.[ch] * app/base/threshold.[ch]: the lowlevel color correction functions plus their parameter structs cut out of the resp. tools. * app/core/core-enums.[ch]: removed GimpTransferMode enum... * app/base/base-enums.[ch]: ...added it here. Also added GimpHueRange for the new hue-saturation files. * tools/pdbgen/enums.pl * libgimp/gimpenums.h * plug-ins/script-fu/script-fu-constants.c: regenerated. * app/tools/Makefile.am * app/tools/gimpcolorbalancetool-transfer.c: removed (code went to base/color-balance.c). * app/tools/gimpimagemaptool.[ch]: added most code which was diplicated in subclasses. Create the dialog here with a nice title bar including image preview and name (fixes #66033). Added virtual functions map(), dialog() and reset() which need to be implemented by subclasses. * app/tools/gimpbrightnesscontrasttool.[ch] * app/tools/gimpcolorbalancetool.[ch] * app/tools/gimpcurvestool.[ch] * app/tools/gimphuesaturationtool.[ch] * app/tools/gimplevelstool.[ch] * app/tools/gimpposterizetool.[ch] * app/tools/gimpthresholdtool.[ch]: removed tons of duplicated code and simply implement GimpImageMapTool's virtual functions. Removed all dialog structs and keep the variables in the tool structs. The dialogs are now created on-the-fly and destroyed when the tool goes away, which makes all callbacks much simpler and safer. Lots of GUI & code cleanup in all dialogs. * app/tools/gimpcurvestool.c * app/tools/gimplevelstool.c: added separate "Reset Channel" buttons and let the global "Reset" buttons reset all color channels. * app/tools/tools.c: the various antique foo_free() functions don't exist any more. * app/tools/gimphistogramtool.c: removed ImageMap field from dialog struct (it was unused). Cleaned up dialog a bit. * tools/pdbgen/Makefile.am: don't scan tools/gimphuesaturationtool.h for enums. * tools/pdbgen/pdb/color.pdb: use the new stuff from base/ and don't include stuff from tools/ any more. * app/pdb/color_cmds.c * app/pdb/paint_tools_cmds.c: regenerated.
