David Schleef	4ee3afc051	cog: Improve RGB<->YCbCr matrixing ... YCbCr->RGB now has a 'bits' setting, which controls the number of bits used for the matrix coefficients. Choices are 6 or 8. 6 is low quality, but faster. RGB->YCbCr now works. Always works in 8 bit, since it's the same speed as 6 bit.	2009-10-24 11:38:42 -07:00

David Schleef	3c870a7a6c	cog: reset cache instead of returning NULL ... Returning NULL makes things crash. Resetting the cache makes things run slow. Still an underlying bug somewhere, but not critical.	2009-10-02 21:58:26 -07:00
