* jumper, rework callback a bit, use it for color_lookup_tableGravatar Mike Klein2017-04-21
| | | | | | | | | | | | | | | | | | | | | | | | | | Looks like the color-space images have this well tested (even without lab_to_xyz) and the diffs look like rounding/FMA. The old plan to keep loads and stores outside callback was: 1) awkward, with too many pointers and pointers to pointers to track 2) misguided... load and store stages march ahead by x, working at ptr+0, ptr+8, ptr+16, etc. while callback always wants to be working at the same spot in the buffer. I spent a frustrating day in lldb to understood 2). :/ So now the stage always store4's its pixels to a buffer in the context before the callback, and when the callback returns it load4's them back from a pointer in the context, defaulting to that same buffer. Instead of passing a void* into the callback, we pass the context itself. This lets us subclass the context and add our own data... C-compatible object-oriented programming.

* Move shader register setup to SkRasterPipelineBlitter.Gravatar Mike Klein2017-01-23
| | | | | | | | | | | | | | | | | | | | | We've been seeding the initial values of our registers to x+0.5,y+0.5, 1,0, 0,0,0,0 (useful values for shaders to start with) in all pipelines. This CL changes that to do so only when blitting, and only when we have a shader. The nicest part of this change is that SkRasterPipeline itself no longer needs to have a concept of y, or what x means. It just marches x through [x,x+n), and the blitter handles y and layers the meaning of "dst x coordinate" onto x. This ought to make SkSplicer a little easier to work with too. dm --src gm --config f16 srgb 565 all draws the same.

* 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.

| | | | | | | | | | | | | | | | | | | | Changed ICC parsing/SkGammas/SkColorLookUpTable to handle non-3-channel inputs. Parsed CMYK A2B ICC profiles. Integrated this with SkJpegCodec (the only file that supports CMYK) and SkColorSpaceXform_A2B to allow parsing and color xforming of ICC CMYK images.

* Consistent naming.Gravatar Mike Klein2016-11-29
| | | | | | | | | | | | | | | For stages that have {r,g,b,a} and {dr,dg,db,da} versions, name the {r,g,b,a} one "foo" and the {dr,dg,db,da} on "foo_d". The {r,g,b,a} registers are the ones most commonly used and fastest, so they get short ordinary names, and the d-registers are less commonly used and sometimes slower, so they get a suffix. Some stages naturally opearate on all 8 registers (the xfermodes, accumulate). These names for those look fine and aren't ambiguous. Also, a bit more re-arrangement in _opts.h.

* Start each pipeline with (x,y) in (dr,dg) registers for the shader.Gravatar Mike Klein2016-11-15
| | | | | | | | | | | | | | | | | | | | | Image shaders need to do some geometry work before sampling the image colors: 1) determine dst coordinates 2) map back to src coordinates 3) tiling Feeding (x,y) through as (dr,dg) registers makes step 1) easy, perhaps trivial, while leaving (r,g,b,a) with their usual meanings, "the color", starting with the paint color. This is easy to tweak into something like (x+0.5, y+0.5, 1) in (dr,dg,db) once this lands. Mostly I just want to get all the uninteresting boilerplate out of the way first.

* 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.
