* Test sk_linear_to_srgb() less exhaustively in Debug mode.Gravatar mtklein2016-08-08
| | | | | | | | | | It's pretty slow when not optimized... it can take ~5 minutes to run. This makes it take ~2 seconds on my laptop. BUG=skia: GOLD_TRYBOT_URL= https://gold.skia.org/search?issue=2221803002 Review-Url: https://codereview.chromium.org/2221803002
* Tune linear->sRGB constants to round-trip all bytes.Gravatar mtklein2016-07-20
| | | | | | | | | | | | I basically just ran a big 5-deep for-loop over the five constants here. This is the first set of coefficients I found that round trips all bytes. I suspect there are many such sets.

* Update rounding/clamping comments on sk_linear_to_srgb().Gravatar mtklein2016-07-19
| | | | | | | | | Rounding is enough. No need for an explicit clamp if the inputs are in range. BUG=skia: GOLD_TRYBOT_URL= https://gold.skia.org/search?issue=2161223002 Review-Url: https://codereview.chromium.org/2161223002
* Move sRGB <-> linear conversion components to their own files.Gravatar mtklein2016-07-08
| | | | | | | | | | | | | | | This makes them a little easier to use outside SkColorXform code. I've added some notes about how best to use them and their eccentricities, and added a test. Ultimately any software sRGB <-> linear conversion should funnel somehow through here.

* Revert of Move sRGB <-> linear conversion components to their own files. ↵Gravatar mtklein2016-07-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (patchset #5 id:80001 of https://codereview.chromium.org/2128893002/ ) Reason for revert: Monotonicity assert is failing on ARM. (Different rsqrt() and invert() precision?) Will investigate a bit tomorrow... might reland with the test TODO.

This makes them a little easier to use outside SkColorXform code. I've added some notes about how best to use them and their eccentricities, and added a test.
