* remove append_from_srgb()Gravatar Mike Klein2017-12-18

* Rework out-of-gamut handling in SkRasterPipelineGravatar Mike Klein2017-12-18
| | | | | | | | | | | | | | | | | | | | | | Instead of trying to carefully manage the in-gamut / out-of-gamut state of the pipeline, let's do what a GPU would do, clamping to representable range in any float -> integer conversion. Most effects doing table lookups now clamp themselves internally, and the store_foo() methods clamp when the destination is fixed point. In turn the from_srgb() conversions and all future transfer function stages can care less about this stuff. If I'm thinking right, the _lowp side of things need not change at all, and that will soften the performance impact of this change. Anything that was fast to begin with was probably running a _lowp pipeline.

* add srcover_bgra_8888Gravatar Mike Klein2017-10-24
| | | | | | | | | | | | | | Chrome generally uses BGRA buffers, so srcover_rgba_8888 isn't really doing them any good. Probably a good idea to cover both kN32 options any time we specialize like this? There's one small diff, so I've lazily guarded this by SK_LEGACY_LOWP_STAGES, which I want to rebaseline today anyway.

* rework plus blend modeGravatar Mike Klein2017-08-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The most interesting parts of this are how plus interacts with partial coverage. Plus needs its clamp to happen after the lerp. Luckily, some of its math folds away: d' = clamp[ d*(1-c) + (s+d)*c ] == clamp[ d - dc + sc + dc ] == clamp[ d + sc ] What's nice there is that coverage can be folded into the src term. This suggests that we can re-write the plus stage to clamp internally (and thus, be viable for 8-bit) if we always pre-scale with coverage. We don't have a way to pre-scale with 565 coverage until now, but it's only a step or two away from there. We can use the alternate formulation we derived for alpha for lerp_565, calculating the alpha coverage from red, green, and blue coverages _and_ the values of src and dst alpha. While we already pre-scale srcover today for 8-bit or constant coverage, we cannot do the same for 565. When evaluating the expression d' = s + (1-a)d we need the a term to be pre-scaled with red's coverage when calculating dr', with blue's when calculating db', etc. Essentially we need to carry around a bunch of extra values, and we've got no way to do that. So instead, we'll just carefully pre-scale plus with any coverage, and keep post-lerping srcover when we have 565 coverage.

* refactor SkRasterPipelineBlitterGravatar Mike Klein2017-05-22
| | | | | | | | | | | | | | | | | This refactors the factories so that the create-from-paint factory is a front-patch to the create-from-shader-pipeline factory. Feature-wise, we make the pre-baked shader pipeline responsible for modulating by paint alpha; the factory only adds when creating from the paint. We can fold the alpha into the colors in drawVertices, which makes it run a bit faster, dropping the need for a scale_1_float runtime stage. This causes a few invisible diffs on the "vertices" GM, but everything else draws the same.

| | | | | | | | | | | | | | | | This CL, just to limit its size/complexity, only handles colors but not textures. Future CLs will cover everything. Performance is pretty exciting. Its faster than the old code-path, and when we fix a bug in pathutils to preserve opaqueness, it gets a lot faster (8 -> 5) Bug: skia: Change-Id: I4113060e25fe25fe4e6a0ea59bd4fa5e33abc668 Reviewed-on: https://skia-review.googlesource.com/17276 Commit-Queue: Mike Reed <reed@google.com> Reviewed-by: Mike Klein <mtklein@chromium.org> Reviewed-by: Florin Malita <fmalita@chromium.org>
* Make SkCreateRasterPipelineBlitter() not fail.Gravatar Mike Klein2017-05-10
| | | | | | | | | | | | | | Mostly this is about extending the fallback in SkShader::appendStages() to cover more cases, and making sure subclasses call appendStages() so they can get the fallback, not onAppendStages() directly. We still need to watch for SkShader::makeContext() failing in the fallback itself, so sadly SkShader::appendStages() may still fail.

* Make SkColorFilter::appendStages() not fail.Gravatar Mike Klein2017-05-09
| | | | | | | | | | | | | | | | | | This makes SkColorFilter::appendStages() first try onAppendStages(), and if it's unimplemented or fails, fall back to filterSpan4f(). This also makes onAppendStages() private to try to ensure that appendStages() is now its only caller, ensuring everyone goes through this fallback path. The fallback uses the color filter transformed into the dst colorspace using our new SkColorSpaceXformer... that seem ok Matt?

* "can we?" -> "do we want to?" for SkRasterPipelineBlitterGravatar Mike Klein2017-05-08
| | | | | | | | | | | | | | | | | There has been a supported() function in SkRasterPipelineBlitter.cpp for a long time that's becoming increasingly misnamed. That blitter ought to be able to handle all destination formats. This CL moves that logic outside to the creator of the blitter, changing it from "can we handle this format?" to "do we want to use this blitter for this format?". In other CLs I'm working to make creating a pipeline blitter never fail.

| | | | | | | | | | | | | | I've decided to ignore our existing CPU implementations and start from scratch, mostly referencing the GL ES 3.2 spec and w3 spec. This implementation ought to look a lot like the reference implementation I've written in gm/hsl.cpp, with the addition of handling alpha: unpremul, blend, re-premul with a simple SrcOver alpha.

* move dither after the transfer functionGravatar Mike Klein2017-05-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There's no single dither rate that we can use in linear space if we're using a non-linear transfer function... if it's too high (like today) we'll dither too much around zero (e.g. 0 -> 5), and if it's too low we won't dither near one. We were thinking it'd be a good idea to move the dither later in the pipeline anyway. This has to be the right spot! Now that we're moving dither from operating in linear space to operating in bit-space (after transfer function, aware of bit-depth of destination) we have to start clamping [0,1] instead of [0,a]... But, I think I've rewritten things to make sure we don't need to clamp at all. The main idea is to make sure 0-dither and 1+dither round to 0 and 1 respectively. We can do this by making the dither span exclusive, switching from [-0.5,+0.5] to (-0.5,+0.5). In practice I'm doing that as [-0.4921875,+0.4921875], a maximum dither of 63/128 of a bit. Similarly, I don't think it makes sense to fold in the multiply by alpha anymore if we're after the transfer function.
