Revision history for Perl extension Graphics::ColorObject.
0.5.0 2005/10/12
- added gamut checks and clipping (not all colorspaces
supported yet)
- added several color-difference algorithms
- added arbitrary white-points (any temperature from 4000K to 25000K)
- added several predefined white-points, and made others more accurate
- added YUV, YIQ, PhotoYCC spaces
- added documentation
- changed many conversion matrices to be more accurate
(from 3 significant digits to >5)
- bug: HSL_to_RGB incorrect hue round-off produced rare but
significant errors in H (fixed)
- bug: wrong implicit colorspaces in colorbars test caused some
tests to fail (fixed)
0.4a4 2004/03/07 23:00:48
- added convert-color.pl in examples, fixed draw-lab-colorspace.pl
- bug: converting anything to xyY failed (and the tests didn't catch it) (fixed)
- general cleanup, now we run with use strict and use warnings
- changed dependency to be perl 5.6, not 5.8
0.4a3 2004/03/05 00:39:46
- bug: tests weren't working properly (fixed)

- added Luv and LCHuv color spaces
- minor documentation fixes
0.4a2 2004/03/04 20:26:00
