Member Function Documentation

CacheRuntimeStage()

virtual void flutter::SnapshotDelegate::CacheRuntimeStage ( const std::shared_ptr< impeller::RuntimeStage > &  runtime_stage )

pure virtual

Load and compile and initial PSO for the provided [runtime_stage].

Impeller only.

ConvertToRasterImage()

virtual sk_sp< SkImage > flutter::SnapshotDelegate::ConvertToRasterImage ( sk_sp< SkImage >  image )

pure virtual

GetGrContext()

virtual GrDirectContext * flutter::SnapshotDelegate::GetGrContext ( )

pure virtual

Implemented in flutter::Rasterizer.

GetTextureRegistry()

virtual std::shared_ptr< TextureRegistry > flutter::SnapshotDelegate::GetTextureRegistry ( )

pure virtual

Gets the registry of external textures currently in use by the rasterizer. These textures may be updated at a cadence different from that of the Flutter application. When an external texture is referenced in the Flutter layer tree, that texture is composited within the Flutter layer tree.

Returns

A pointer to the external texture registry.

Implemented in flutter::Rasterizer.

MakeRasterSnapshot()

virtual void flutter::SnapshotDelegate::MakeRasterSnapshot ( sk_sp< DisplayList >  display_list, SkISize  picture_size, std::function< void(sk_sp< DlImage >)>  callback  )

pure virtual

MakeRasterSnapshotSync()

virtual sk_sp< DlImage > flutter::SnapshotDelegate::MakeRasterSnapshotSync ( sk_sp< DisplayList >  display_list, SkISize  picture_size  )

pure virtual

MakeSkiaGpuImage()

virtual std::unique_ptr< GpuImageResult > flutter::SnapshotDelegate::MakeSkiaGpuImage ( sk_sp< DisplayList >  display_list, const SkImageInfo &  image_info  )

pure virtual

Attempts to create a GrBackendTexture for the specified DisplayList. May result in a raster bitmap if no GPU context is available.
