Mon Jan 31 22:43:48 CET 2000 Sven Neumann <sven@gimp.org>
* libgimp/gimpcolorspace.c
* libgimp/gimpcolorspace.h: added INTENSITY() macro
* app/blend.c
* app/convert.c
* app/gimpimage.c
* app/temp_buf.c: use INTENSITY() from libgimp
* plug-ins/common/bumpmap.c
* plug-ins/common/colorify.c
* plug-ins/common/compose.c
* plug-ins/common/decompose.c
* plug-ins/common/displace.c
* plug-ins/common/engrave.c
* plug-ins/common/gradmap.c
* plug-ins/common/newsprint.c
* plug-ins/gflare/gflare.c
* plug-ins/maze/handy.c
* plug-ins/pagecurl/pagecurl.c
* plug-ins/print/print-util.c
* plug-ins/rcm/rcm.c
* plug-ins/rcm/rcm.h
* plug-ins/rcm/rcm_callback.c
* plug-ins/rcm/rcm_dialog.c
* plug-ins/rcm/rcm_gdk.c
* plug-ins/rcm/rcm_misc.c
* plug-ins/rcm/rcm_misc.h: use INTENSITY() and other
color_conversion_routines from libgimp. I'm not sure if I have
tested all this properly (I tried to do), so if you are bored,
please play around with the changed plug-ins.
Mon Jan 31 21:52:27 CET 2000 Stanislav Brabec <utx@penguin.cz>
* plug-ins/common/vinvert.c: Typo fix.

* One bug, two effects:
*
* 1) Handle 4-color correctly (it was treating the 4-color too much like the
* 6-color).
*
* 2) An attempt to handle both cases with the same code path led to a
* discontinuity that depending upon the orientation of a color gradient would
* lead to either white or dark lines at the point that the dark version of
* the color would kick in.

*
* -Yosh
*
* Revision 1.14 1998/05/16 18:27:59 mike
* Cleaned up dithering functions - unnecessary extra data in dither buffer.
*
* Revision 1.13 1998/05/13 17:00:36 mike
* Minor change to CMYK generation code - now cube black difference value
* for better colors.
*
* Revision 1.12 1998/05/08 19:20:50 mike
* Updated CMYK generation code to use new method.
* Updated dithering algorithm (slightly more uniform now, less speckling)
* Added default media size function.
*
* Revision 1.11 1998/03/01 18:03:27 mike
* Whoops - need to add 255 - alpha to the output values (transparent to white
* and not transparent to black...)
*
* Revision 1.10 1998/03/01 17:20:48 mike
* Updated alpha code to do alpha computation before gamma/brightness lut.
*
* Revision 1.9 1998/03/01 17:13:46 mike
* Updated CMY/CMYK conversion code for dynamic BG and hue adjustment.
* Added alpha channel support to color conversion functions.
*
* Revision 1.8 1998/01/21 21:33:47 mike
* Replaced Burkes dither with stochastic (random) dither.
*
* Revision 1.7 1997/10/02 17:57:26 mike
* Replaced ordered dither with Burkes dither (error-diffusion).
* Now dither K separate from CMY.
*
* Revision 1.6 1997/07/30 20:33:05 mike
* Final changes for 1.1 release.
*
* Revision 1.5 1997/07/26 18:43:04 mike
* Fixed dither_black and dither_cmyk - wasn't clearing extra bits
* (caused problems with A3/A4 size output).
*
* Revision 1.5 1997/07/26 18:43:04 mike
* Fixed dither_black and dither_cmyk - wasn't clearing extra bits
* (caused problems with A3/A4 size output).
*
* Revision 1.4 1997/07/02 18:46:26 mike
* Fixed stupid bug in dither_black() - wasn't comparing against gray
* pixels (comparing against the first black byte - d'oh!)
* Changed 255 in dither matrix to 254 to shade correctly.
*
* Revision 1.4 1997/07/02 18:46:26 mike
* Fixed stupid bug in dither_black() - wasn't comparing against gray
* pixels (comparing against the first black byte - d'oh!)
* Changed 255 in dither matrix to 254 to shade correctly.
*
* Revision 1.3 1997/07/02 13:51:53 mike
* Added rgb_to_rgb and gray_to_gray conversion functions.
* Standardized calling args to conversion functions.
*
* Revision 1.2 1997/07/01 19:28:44 mike
* Updated dither matrix.
* Fixed scaling bugs in dither_*() functions.
