MakeRasterSnapshot()

virtual void flutter::SnapshotController::MakeRasterSnapshot ( sk_sp< DisplayList >  display_list, DlISize  picture_size, std::function< void(const sk_sp< DlImage > &)>  callback, SnapshotPixelFormat  pixel_format  )

pure virtual

Implemented in flutter::SnapshotControllerImpeller, and flutter::SnapshotControllerSkia.

MakeRasterSnapshotSync()

virtual sk_sp< DlImage > flutter::SnapshotController::MakeRasterSnapshotSync ( sk_sp< DisplayList >  display_list, DlISize  picture_size, SnapshotPixelFormat  pixel_format  )

pure virtual

Implemented in flutter::SnapshotControllerImpeller, and flutter::SnapshotControllerSkia.

MakeRenderContextCurrent()

virtual bool flutter::SnapshotController::MakeRenderContextCurrent ( )

pure virtual

Implemented in flutter::SnapshotControllerImpeller, and flutter::SnapshotControllerSkia.

MakeTextureImage()

virtual sk_sp< DlImage > flutter::SnapshotController::MakeTextureImage ( sk_sp< SkImage >  image, SnapshotPixelFormat  pixel_format  )

pure virtual

Creates a texture-backed DlImage from the provided SkImage.

This is primarily used by decodeImageFromPixelsSync to upload pixels to the GPU synchronously.

Implemented in flutter::SnapshotControllerImpeller, and flutter::SnapshotControllerSkia.
