* add explicit accessor for sRGB singleton colorspacesGravatar Mike Klein2018-07-25
| | | | | | | | | | | | | | SkColorSpace::MakeSRGB().get() is scary, and causes more ref/unref pairs than strictly necessary for these singletons. This time the implementation is still in SkColorSpace.cpp, so these should really work as singletons.

* Fix Adobe RGB color space in SkiaGravatar Brian Osman2017-12-20
| | | | | | | | | | | | | | | | Our runtime definition of the XYZ matrix was fairly inaccurate. It also didn't round-trip through ICC fixed point correctly. Now, constructing the color space at runtime produces exactly the same matrix as constructing the space from the ICC profile. And the values can then be serialized back to ICC exactly. This eliminates the need for the snapping logic, too.

* Rename all color space factories from New* to Make*Gravatar Brian Osman2016-10-24
| | | | | | | | | | | | | | | | | | | | | Matches our naming convention for all other types - factories that return sk_sp (or any type that intelligently manages its own lifetime) are named Make. Previous factories are still around, assuming SK_SUPPORT_LEGACY_COLOR_SPACE_FACTORIES is defined. Enable that define for Android, etc. See also: https://codereview.chromium.org/2442053002/ BUG=skia: GOLD_TRYBOT_URL= https://gold.skia.org/search?issue=3822 Change-Id: Iaea9376490736b494e8ffc820831f052bbe1478d Reviewed-on: https://skia-review.googlesource.com/3822 Commit-Queue: Brian Osman <brianosman@google.com> Reviewed-by: Mike Reed <reed@google.com>

* Refactored SkColorSpace and added in a Lab PCS GMGravatar raftias2016-10-18
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | This is only useful in the rare case that the dst does not fall into one of our main paths. But it's a good optimization, since this does happen, and typically, the dst won't change.

* Removed makeLinearGamma() from the public API for SkColorSpaceGravatar raftias2016-10-13
| | | | | | | | | | | | | | | It will now reside in SkColorSpace_Base. Future work for SkColorSpace will cause this function to not be desirable or sensible to call on all SkColorSpaces. Call sites were changed to make a kSRGBLinear_Named instead of kSRGB_Named -> makeLinearGamma() (the majority of cases), and if that was not possible, SkColorSpace_Base::makeLinearGamma() was called instead.

* Added kSRGBLinear_Named color space, along with testsGravatar brianosman2016-09-27
| | | | | | | | | | | | Gradients (and other shaders) are going to end up serializing this particular color space very frequently, so we want a shorthand way of writing it out. I think it's also helpful to have a clearer way of creating it (vs. NewNamed(kSRGB_Named)->makeLinearGamma()).
