* remove SkColorSpace_BaseGravatar Mike Klein2018-01-26
| | | | | | | | | | | | The type SkColorSpace_Base doesn't need to exist. Its one type() query can be answered instead by toXYZD50(). Now all that's left in the file is SkGammas, so rename it to SkGammas.h.

* Simplify SkColorSpace::MakeICCGravatar Leon Scroggins III2017-10-31
| | | | | | | | | | | | | | | | | | | Rather than restricting the supported ICC types in MakeICC, create any ICC type that we support, and make the client reject them as necessary by querying the SkColorSpace::Type. Remove ICCTypeFlag and replace uses of it with SkColorSpace::Type. This depends on a change in Chromium (https://chromium-review.googlesource.com/c/chromium/src/+/741843). Without that, this change will start allowing non-CMYK images to use CMYK profiles.

* Unify ICC support for gray jpegs and gray pngsGravatar Matt Sarett2017-01-13
| | | | | | | | | | | | | | | | | | | | | | (1) Parse ICC gray profiles into RGB SkColorSpace objects. This is easy - "gray transfer fn + white point" is subset of "RGB transfer fns + matrix". This makes it easier/possible for the drawing code to reason about color spaces attached to kGray buffers. (2) Allow gray images to be tagged with gray ICCs OR rgb ICCs. ICC gray forces to designer to use "D50 gray". It is not uncommon to see gray images with RGB profiles - and this actually allows the designer to choose more kinds of gray (ex: sRGB gray). (3) Make SkJpegCodec support gray images with RGB ICCs. (4) Make SkPngCodec support gray images with Gray ICCs. (5) Delete gray from SkColorSpace_A2B - we no longer create these objects for gray profiles.

* Rearrange ICC profile parsingGravatar Matt Sarett2016-12-16
| | | | | | | | | | | | | | | | | | | | | | | None of the small details have changed, just some high level reorganization: (1) Check for XYZ spaces before A2B. (2) If we fail to parse the XYZ space, fallback by trying to parse the A2B space. This should cause no image diffs on Gold. There is an image from the ICC website that is *supposed* to test that we parse the A2B tag before the XYZ tag. Our behavior on this image will actually not change - the XYZ tag is invalid (non-D50 matrix), so we fall back to A2B anyway. I think this behavior is ok.

The refactoring breaks off A2B0 tag support into a separate subclass of SkColorSpace_Base, while keeping the current (besides CLUT) functionality in a XYZTRC subclass. ICC profile loading is now aware of this and creates the A2B0 subclass when SkColorSpace::NewICC() is called on a profile in need of the A2B0 functionality. The LabPCSDemo GM loads a .icc profile containing a LAB PCS and then runs a Lab->XYZ conversion on an image using it so we can display it and test out the A2B0 SkColorSpace functionality, sans a/b/m-curves, as well as the Lab->XYZ conversion code.
