| Skia Graphics Release Notes |
| |
| This file includes a list of high level updates for each milestone release. |
| |
| * * * |
| |
| Milestone 84 |
| |
| * <insert new release note here> |
| |
| * Remove unused SkMaskFilter helpers: compbine, compose |
| Note: shadermaskfilter will likely be removed next (clipShader should serve) |
| |
| * Add back SkCanvas::kPreserveLCDText_SaveLayerFlag to indicate that saveLayer() |
| will preserve LCD-text. All text in the layer must be drawn on opaque background |
| to ensure correct rendering. |
| |
| * Add the new directory client_utils/ for code that is specific to a single client and |
| should be considered separate from Skia proper. Move SkFrontBufferedStream into the |
| subdir android/. |
| |
| * SkBitmap and SkPixmap's erase() methods now treat their color parameters |
| consistently with the rest of Skia, with all SkColors and any untagged |
| SkColor4fs interpreted as sRGB, not as a color in the bitmap's color space. |
| SkPixmap::erase(SkColor4f) now takes an SkColorSpace, so you can pass |
| pixmap.colorSpace() if you want the old behavior. |
| |
| * SkCamera.h and SkMatrix44.h are DEPRECATED. |
| Use SkM44 if you want to have 3d transformations. |
| |
| * Changed Dilate and Erode image filters to take SkScalar for radius instead of int. While |
| the image filters themselves are defined in terms of discrete pixels, the radii provided by |
| the user are mapped through the CTM so taking ints forced over discretization. After mapping |
| through the CTM the radii are now rounded to pixels. |

| https://review.skia.org/282636 |
| |
| * Updated the contract of GrContext and SkSurface flush calls in regards to semaphores. Made it |
| clear that the caller is responsible for deleting any initialized semaphores after the flush |
| call regardless if we were able to submit them or not. Also, allows skia to only submit a |
| subset of the requested semaphores if we failed to create some. |
| https://review.skia.org/282265 |
| |
| |
| * SkCanvas::drawVertices will now always fill the triangles specified by the vertices. Previously, |
| vertices with no colors and no (texture coordinates or shader) would be drawn in wireframe. |
| https://review.skia.org/282043 |
| |
| * * * |
| |
| Milestone 83 |
| |
| * Remove localmatrix option from SkShaders::[Blend, Lerp] |
| |
| * Fill out Direct3D parameters for backend textures and backend rendertargets. |
| |
| * SkImage::makeTextureImage() takes an optional SkBudgeted param |
| |
| * Made non-GL builds of GPU backend more robust. |
| https://review.skia.org/277456 |
| |
| * MoltenVK support removed. Use Metal backend instead. |
| https://review.skia.org/277612 |
| |
| * * * |
| |
| Milestone 82 |
| |
| * Removed drawBitmap and related functions from SkDevice; all public drawBitmap functions on |
| SkCanvas automatically wrap the bitmap in an SkImage and call the equivalent drawImage function. |
| Drawing mutable SkBitmaps will now incur a mandatory copy. Switch to using SkImage directly or |
| mark the bitmap as immutable before drawing. |
| |
| * Removed "volatile" flag from SkVertices. All SkVertices objects are assumed to be |
| volatile (the previous default behavior). |
| |
| * Removed exotic legacy bitmap functions from SkCanvas (drawBitmapLattic, drawBitmapNine); the |
| exotic SkImage functions still exist. |
| |
| * Make it possible to selectively turn on/off individual encoders/decoders, |
| using skia_use_(libpng/libjpeg_turbo/libwebp)(decode/encode). |
| |
| * Removed GrGpuResource, GrSurface, and GrTexture from public api. These were not |
| meant to be public, and we now can move them into src. Also removed getTexture |
| function from SkImage.h |
| |
| * Removed Bones from SkVertices |
| |
| * Added a field to GrContextOptions that controls whether GL errors are checked after |
| GL calls that allocate textures, etc. It also controls checking for shader compile |
| success, and program linking success. |
| |
| * Made SkDeferredDisplayList.h officially part of the public API (i.e., moved it to |
| include/core). Also added a ProgramIterator to SkDeferredDisplayList which allows |
| clients to pre-compile some of the shaders the DDL requires. |
| |
| * 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. |
| |
| * Add new APIs to add attributes to document structure node when |
| creating a tagged PDF. |
| |
| * 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. |
| |
| * Enforce the existing documentation in SkCanvas::saveLayer that it ignores |
| any mask filter on the restore SkPaint. The 'coverage' of a layer is |
| ill-defined, and masking should be handled by pre-clipping or using the |
| auxiliary clip mask image of the SaveLayerRec. |
| |
| * * * |
| |
| 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 |
| |
| * * * |
| |

| |
| * 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() |
| https://review.skia.org/244882 |
| |
| * Remove Vulkan/Metal float32 RGBA texture support |
| https://review.skia.org/244881 |
| |
| * Add SkSurface::MakeFromCAMetalLayer |
| https://review.skia.org/242563 |
| |
| * 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 |

| |
| * 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 |

| |
| * SkImage: new factories: DecodeToRaster, DecodeToTexture |
| https://review.skia.org/234476 |

| not backed by external images. |
| https://review.skia.org/233776 |
| |
