f13ffac7bd Removed the experimental luma-chroma color format.
It was a worthwhile experiment, but for it to really work it needs
a really proper luma-chroma separation, which is both slower than
I really want, and requires knowing the colorspace being used.

I might make another go at this based on the TIFF LogLUV color
format, requiring XYZ as input.

c1f516c2b6 Use a better chroma formula for the RGB32 format.
This makes much better use of the bit space.

bd6cf359b4 Some code clean-up in the RGB32 encoding/decoding code. 2020-09-13 06:44:42 +09:00
d6ab9d06be More work on the packed HDR RGB 32-bit format.
Switched to a different chroma encoding, which is notably faster
and never produces negative values when decoded.

ff9a56977a Use bit fiddling to avoid some expensive operations in trifloat encoding/decoding. 2018-11-23 22:31:28 -08:00
3d1ade21c2 Better naming for the trifloat functions. 2018-11-23 21:38:27 -08:00
3fb22fdefa Implemented a "tri-float" encoding, similar to RGBE.
This implementation trades less range for more precision, giving
9 bits to each mantissa instead of just 8 bits as in RGBE.
