|
|
* 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

|
*
|
|
* 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
