* update SkColor4f::FromColor() to preserve transfer functionGravatar Mike Klein2018-07-12
| | | | | | | | | | | | This kills off some sRGB tables, and lots of call sites can now use SkColor4f::FromColor(). It doesn't seem important to keep this test.

| | | | | | | | | | | It's now no different than append(from_srgb). Bug: skia:7419 Change-Id: I97c59b6987f033ec2f1859db40ca3056b87b370a Reviewed-on: https://skia-review.googlesource.com/86741 Reviewed-by: Brian Osman <brianosman@google.com> Commit-Queue: Mike Klein <mtklein@chromium.org>
* funnel all constant colors through append_constant_color()Gravatar Mike Klein2017-08-03
| | | | | | | | | | | | | | | | My next step is to change the uniform_color context to struct { float r,g,b,a; uint32_t rgba; }; so that it's trivial to load in both float and 8-bit pipelines.

| | | | | | | | | | | | 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.
