* Gradients are serialized (and can be constructed) as SkColor4f + SkColorSpaceGravatar brianosman2016-09-28
| | | | | | | | | | | | | | | | | | | | Added gradient shader factories that take SkColor4f + SkColorSpace. Modified Descriptor to only store SkColor4f + SkColorSpace. Existing factories make use of helper code to convert SkColor and forward to the new factories. Bumped SKP version to handle new gradient serialization format. I was toying with using half-float when serializing SkColor4f, despite my aggressive packing of flags, this format is significantly bigger. Also added GM to use 4f factories. This GM should (and does) look identical to the existing gradients GM. BUG=skia: GOLD_TRYBOT_URL= https://gold.skia.org/search?issue=2370063002 Review-Url: https://codereview.chromium.org/2370063002
* Add storage and computation of SkColor4f version of gradient stops.Gravatar brianosman2016-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | For now, we still only have the SkColor factory, but the Descriptor can now carry either an SkColor or SkColor4f specified gradient. Base class constructor automatically populates both forms of color, so that legacy raster backend will continue to work, and new backend work can operate directly from the float4 version. On the GPU side, we have similar logic, but GrGradientEffect only keeps one version of colors around: SkColor if the destination is legacy, and SkColor4f (with an optional gamut xform) if the destination is gamma correct. The 4f colors are already linear, and we gamut xform them in setData, so gradients are now fully color-correct in sRGB and F16 modes... ... unless there are more than three stops. Then we use a texture, and that code path isn't handled yet. We have a few choices here (do we use an 8-bit sRGB atlas, or just always use F16 linear atlas so we can share it among both sRGB and wide-gamut rendering). In any case, I'd like to defer that to a second CL. This change does fix the non-texture gradients in the gamut GM.
