2002-09-04 Michael Natterer <mitch@gimp.org> More color correction stuff cleanup: * app/base/Makefile.am * app/base/base-types.h * app/base/levels.[ch]: new files containing levels_lut_func(), a new "Levels" parameter struct and the "auto levels" stuff. * app/base/lut-funcs.[ch]: removed the levels stuff here, added lots of g_return_if_fail(). * app/base/color-balance.[ch] * app/base/hue-saturation.[ch]: added init() and reset() functions so we don't need to duplicate this code in the tool and the pdb wrappers. * app/base/curves.[ch]: s/gint/GimpHistogramChannel/g, made curves_channel_reset() initialize the curves array. * app/tools/gimpcolorbalancetool.[ch]: use the new functions, moved the "Range" frame to the top, added a per-range "Reset" button, made the global "Reset" button reset all ranges and the "Preserve Luminosity" toggle. * app/tools/gimpcurvestool.[ch]: don't initialize the curves array manually, as curves_channel_reset() does that, s/gint/GimpHistogramChannel/g. * app/tools/gimphuesaturationtool.c: use the new functions, added a per-channel "Reset" button and made the global "Reset" button reset all channels, cleaned up the GUI update function. * app/tools/gimplevelstool.[ch]: changed to use the new Levels parameter struct and it's utility functions. Removed stuff which now lives in base/levels.c * app/tools/gimpimagemaptool.c: align the "Preview" button bottom-left, not bottom-right. * tools/pdbgen/pdb/color.pdb: use the new stuff and removed uglyness because using the "Levels" struct makes the code more straightforward. * app/pdb/color_cmds.c: regenerated.
