◆ 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.

SnapshotPixelFormat  pixel_format 
)
pure virtual

◆ MakeImpellerSnapshotSync()

virtual std::shared_ptr< impeller::Texture > flutter::SnapshotDelegate::MakeImpellerSnapshotSync ( sk_sp< DisplayList >  display_list,

SnapshotPixelFormat  pixel_format 
)
pure virtual

◆ MakeRenderContextCurrent()

virtual bool flutter::SnapshotDelegate::MakeRenderContextCurrent ( )
pure virtual

Bind a context to the current thread that can execute rendering commands.

Impeller only.

◆ 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.

◆ MakeSkiaSnapshot()

virtual void flutter::SnapshotDelegate::MakeSkiaSnapshot ( sk_sp< DisplayList >  display_list,
DlISize  picture_size,

)
pure virtual

◆ MakeSkiaTextureImage()

virtual sk_sp< SkImage > flutter::SnapshotDelegate::MakeSkiaTextureImage ( sk_sp< SkImage >  image,
SnapshotPixelFormat  pixel_format 
)
pure virtual
