Original change's description:
> Support adding attributes to PDF document structure nodes.
>
> This is an important part of writing a tagged PDF. Many of the nodes
> in the document structure tree need additional attributes, just like
> in HTML.
>
> This change aims to add support for a few useful attributes, not to
> be comprehensive.

Skia Graphics Release Notes
|
|
|
|
This file includes a list of high level updates for each milestone release.
|
|
|
|
* * *
|
|
|
|
Milestone 82
|
|
|
|
<Insert new notes here- top is most recent.>
|
|
* Added two new helper methods to SkSurfaceCharacterization: createBackendFormat and
|
|
createFBO0. These make it easier for clients to create new surface characterizations that
|
|
differ only a little from an existing surface characterization.
|
|
|
|
* Removed SkTMax and SkTMin.
|
|
* Removed SkTClamp and SkClampMax.
|
|
* Removed SkScalarClampMax and SkScalarPin.
|
|
* Removed SkMax32 and SkMin32.
|
|
* Removed SkMaxScalar and SkMinScalar.
|
|
|
|
* SkColorSetA now warns if the result is unused.
|
|
|
|
* An SkImageInfo with a null SkColorSpace passed to SkCodec::getPixels() and
|
|
related calls is treated as a request to do no color correction at decode
|
|
time.
|
|
|
|
* Remove CGFontRef parameter from SkCreateTypefaceFromCTFont.
|
|
Use CTFontManagerCreateFontDescriptorFromData instead of
|
|
CGFontCreateWithDataProvider to create CTFonts to avoid memory use issues.
|
|
|
|
* Added SkCodec:: and SkAndroidCodec::getICCProfile for reporting the native
|
|
ICC profile of an encoded image, even if it doesn't map to an SkColorSpace.
|
|
|
|
* SkSurface::ReplaceBackendTexture takes ContentChangeMode as a parameter,
|
|
which allow callers to specify whether retain a copy of the current content.
|
|
|
|
* * *
|
|
|
|
Milestone 81
|
|
|
|
* Added support for GL_NV_fence extension.
|
|
|
|
* Make SkImageInfo::validRowBytes require rowBytes to be pixel aligned. This
|
|
makes SkBitmap match the behavior of raster SkSurfaces in rejecting
|
|
non-aligned rowBytes.
|
|
|
|
* Added an SkImage::MakeRasterFromCompressed entry point. Also updated
|
|
SkImage::MakeFromCompressed to decompress the compressed image data if
|
|
the GPU doesn't support the specified compression type (i.e., macOS Metal
|
|
doesn't support BC1_RGB8_UNORM so such compressed images will always be
|
|
decompressed on that platform).
|
|
|
|
* Added support for BC1 RGBA compressed textures
|
|
|
|
* Added CachingHint to SkImage::makeRasterImage
|
|
|
|
* Added SkAnimatedImage::getCurrentFrame()
|
|
|
|
* Add support to create an SkSurface from an MTKView, with delayed acquisition of
|
|
the MTLDrawable.
|
|
Entry point: SkSurface::MakeFromMTKView
|
|
|
|
* Removed SkIRect::EmptyIRect(). Use SkIRect::MakeEmpty() instead.
|
|
https://review.skia.org/262382/
|
|
|
|
* Moved SkRuntimeEffect to public API. This is the new (experimental) interface to custom SkSL
|
|
shaders and color filters.
|
|
|
|
* Added BC1 compressed format support. Metal and Vulkan seem to only support the BC
|
|
formats on desktop machines.
|
|
|
|
* Added compressed format support for backend texture creation API.
|
|
This adds the following new entry points:
|
|
GrContext::compressedBackendFormat
|
|
GrContext::createCompressedBackendTexture
|
|
The latter method comes in variants that allow color-initialized and
|
|
compressed texture data initialized.
|
|
|
|
* Added SkMatrix::MakeTrans(SkIVector)
|
|
https://review.skia.org/259804
|
|
|
|
* * *
|
|
|
|
Milestone 80
|
|
|
|
* For Vulkan backend, we now require that the VkDevice, Queue, and Instance outlive
|
|
either the destruction or abandoning of the GrContext. Additionally, all
|
|
GrBackendTextures created via GrContext::createBackendTexture calls must be deleted
|
|
before destroying or abandoning the GrContext.
|
|
https://review.skia.org/257921
|
|
|
|
* Removed SkSize& SkSize::operator=(const SkISize&)
|
|
https://review.skia.org/257880
|
|
|
|
* SkISize width() and height() now constexpr
|
|
https://review.skia.org/257680
|
|
|
|
* Added SkMatrix::MakeTrans(SkVector) and SkRect::makeOffset(SkVector).
|
|
https://review.skia.org/255782
|
|
|
|
* Added SkImageInfo::MakeA8(SkISize) and added optional color space parameter to
|
|
SkImageInfo::MakeN32Premul(SkISize).
|
|
|
|
* Added dimensions() and getFrameCount() to SkAnimatedImage
|
|
https://review.skia.org/253542
|
|
|
|
* Removed SkMatrix44 version of toXYZD50 from SkColorSpace. Switched to skcms types in
|
|
transferFn, invTrasnferFn, and gamutTransformTo functions.
|
|
https://review.skia.org/252596
|
|
|
|
* Removed rotation and YUV support from SkColorMatrix
|
|
https://review.skia.org/252188
|
|
|
|
* Added kBT2020_SkYUVColorSpace. This is BT.2020's YCbCr conversion (non-constant-luminance).
|
|
https://review.skia.org/252160
|
|
|
|
* Remove old async read pixels APIs
|
|
https://review.skia.org/251198
|
|
|
|
* Expose SkBlendModeCoeff and SkBlendMode_AsCoeff for Porter-Duff blend modes.
|
|
https://review.skia.org/252600
|
|
|
|
* * *
|
|
|
|
Milestone 79
|
|
|
|
* SkTextBlob::Iter to discover the glyph indices and typefaces in each run
|
|
https://skia-review.googlesource.com/246296
|
|
|
|
* Added support for PQ and HLG transfer functions to SkColorSpace.
|
|
https://skia-review.googlesource.com/c/skia/+/249000
|
|
|
|
* Added new api on GrContext ComputeImageSize. This replaces the hold static helper
|
|
ComputeTextureSize.
|
|
https://skia-review.googlesource.com/c/skia/+/247337
|
|
|
|
* New versions of SkSurface async-rescale-and read APIs that allow client to extend
|
|
the lifetime of the result data. Old versions are deprecated.
|
|
https://review.skia.org/245457
|
|
|
|
* Add SkColorInfo. It's dimensionless SkImageInfo.
|
|
https://review.skia.org/245261
|
|
|
|
* Added SkPixmap-based createBackendTexture method to GrContext. This allows clients to create
|
|
backend resources (initialized with texture data) that Skia/Ganesh doesn't know about/track.
|
|
https://review.skia.org/244676
|
|
|
|
* Add explicit src and dst colorspace parameters to SkColorFilter::filterColor4f()
|
|

|
|
|

|
|
|
|
* Added kAlpha_F16_SkColorType, kRG_F16_SkColorType and kRGBA_16161616_SkColorType.
|
|
This is intended to help support HDR YUV uses case (e.g., P010 and P016). As such,
|
|
the addition is focused on allowing creation of SkPixmaps and SkImages and not
|
|
SkSurfaces (i.e., who wants to render to render to these?)
|
|
https://review.skia.org/241357
|
|
|
|
* Start to move nested SkPath types (e.g. Direction, Verb) up to root level in SkPathTypes.h
|
|
https://review.skia.org/241079
|
|
|
|
* Remove isRectContour and ksNestedFillRects from public
|
|
https://review.skia.org/241078
|
|
|
|
* Added kRG_88_SkColorType. This is intended to help support YUV uses case (e.g., NV12).
|
|
As such, the addition is focused on allowing creation of SkPixmaps and SkImages and not
|
|
SkSurfaces (i.e., who wants to render to RG?)
|
|
https://review.skia.org/239930
|
|
https://review.skia.org/235797
|
|
|
|
* Make the size of program/pipeline caches configurable via
|
|
GrContextOptions::fRuntimeProgramCacheSize
|
|
https://review.skia.org/239756
|
|
|
|
* Added kAlpha_16_SkColorType and kRG_1616_SkColorType. This is intended to help support HDR YUV
|
|
uses case (e.g., P010 and P016). As such, the addition is focused on allowing creation of
|
|
SkPixmaps and SkImages and not SkSurfaces (i.e., who wants to render to render to these?)
|
|
https://review.skia.org/239930
|
|
|
|
* Add GrContext::precompileShader to allow up-front compilation of previously-cached shaders.
|
|
https://review.skia.org/239438
|
|
|
|
* * *
|
|
|
|
Milestone 78
|
|
|
|

|
|
https://review.skia.org/230579
|
|
https://review.skia.org/231736
|
|
|
|
* SkPath::Iter::next() now ignores its consumDegenerates bools. Those will so
|
|
go away entirely
|
|
https://review.skia.org/235104
|
|
|
|
* SkImage: new factories: DecodeToRaster, DecodeToTexture
|
|
https://review.skia.org/234476
|
|
|
|
* SkImageFilter API refactor started:
|
|
- Provide new factory API in include/effects/SkImageFilters
|
|
- Consolidated enum types to use SkTileMode and SkColorChannel
|
|
- Hide filter implementation classes
|
|
- Hide previously public functions on SkImageFilter that were intended for
|
|
internal use only

https://review.skia.org/232839
|
|
|
|
