Detailed Description

A description of a set of BackendTextures that hold the planar data described by a SkYUVAInfo.

Constructor & Destructor Documentation

YUVABackendTextureInfo() [1/3]

skgpu::graphite::YUVABackendTextureInfo::YUVABackendTextureInfo ( )

default

Default YUVABackendTextureInfo is invalid.

YUVABackendTextureInfo() [2/3]

skgpu::graphite::YUVABackendTextureInfo::YUVABackendTextureInfo ( const YUVABackendTextureInfo &  )

default

YUVABackendTextureInfo() [3/3]

skgpu::graphite::YUVABackendTextureInfo::YUVABackendTextureInfo	(	const Recorder *	recorder,
		const SkYUVAInfo &	yuvaInfo,
		SkSpan< const TextureInfo >	textureInfo,
		Mipmapped	mipmapped
	)

Initializes a YUVABackendTextureInfo to describe a set of textures that can store the planes indicated by the SkYUVAInfo. The texture dimensions are taken from the SkYUVAInfo's plane dimensions. All the described textures share a common origin. The planar image this describes will be mip mapped if all the textures are individually mip mapped as indicated by Mipmapped. This will produce an invalid result (return false from isValid()) if the passed formats' channels don't agree with SkYUVAInfo.
