* Initial implementation of a SkColorSpace_A2B xformGravatar raftias2016-11-11
| | | | | | | | | | | | | | | | There is support for all features of SkColorSpace_A2B. Tests for these functionality were adapted from the XYZ xform, plus a CLUT-specific test was added. Shared functions used by both SkColorSpaceXform_XYZ and SkColorSpaceXform_A2B have been moved into a shared header.

* Use SK_ALWAYS_INLINE in SkColorSpaceXformGravatar Matt Sarett2016-10-24
| | | | | | | | | | | | | | | | | | | Two reasons for this: (1) We care about the performance of this code, and Windows isn't very good at inlining. Let's make sure we isntruct the compiler to inline. (2) Since landing uses of this in Chrome, we're seeing flaky LayoutTests that appear to be timing related. I'm (very optimistically) hoping that this will help.

* 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.

* Refactor color_xform_RGBA() to improve performanceGravatar Matt Sarett2016-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we've identified this as the "fast path", it has become (somewhat) stable, and I'm ready to ship it, I feel comfortable playing games with clang to get the behavior we want. toSRGB Performance on HP z620: Before: 370us or 470us (depending on the mood of my computer) After: 345us (or better, always) My guess is that clang optimizers do a better job of interleaving instructions effectively when we put everything into one function. Regardless of being silly about performance, I also acutally prefer how the code reads this way.

(3) Actually need three tables. No reason to waste a bunch of space for these tables on SkColorSpaceXform, when it will likely be unused.

* Reduce overhead for linear color xformsGravatar msarett2016-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We used to build src and dst transfer fn tables every time a new xform was created with linear src and dst. Now we don't compute them because we don't need them. This will make SkColorSpaceXform a far better option for any xforms with float or half-float inputs or outputs, particularly on a small number of pixels. This CL also moves SkColorSpaceXform closer to what I anticipate will be the eventual 'API design'. I think apply() will want to take a SrcColorType enum (not created yet because it's not necessary yet) and a DstColorType enum (still using SkColorType because there's not yet a reason not to). Performance changes: toSRGB 341us -> 366us to2Dot2 404us -> 403us toF16 318us -> 304us There's no reason for toSRGB or to2Dot2 to change. The refactor seems to have caused the compiler to order the instructions a little differently... This is something to come back to if we need to squeeze more performance out of sRGB. For now, let's not be held up by something we don't control. F16 likely improves because we are no longer (unnecessarily) building the linear tables. Code size gets a little bigger. Measuring SkColorSpaceXform size as a percentage of src/ size, we go from 0.8% to 1.4%.

| | | | | | | | | | | | | | | | | | I think we convinced ourselves that denorms, while a good chunk of half floats, cover a rather small fraction of the representable range, which is always close enough to zero to flush. This makes both paths of the conversion to or from float considerably simpler. These functions now work for zero-or-normal half floats (excluding infinite, NaN). I'm not aware of a term for this class so I've called them "ordinary". A handful of GMs and SKPs draw differently in --config f16, but all imperceptibly.
