Detailed Description

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

Constructor & Destructor Documentation

GrYUVABackendTextureInfo() [1/3]

GrYUVABackendTextureInfo::GrYUVABackendTextureInfo ( )

default

Default GrYUVABackendTextureInfo is invalid.

GrYUVABackendTextureInfo() [2/3]

GrYUVABackendTextureInfo::GrYUVABackendTextureInfo	(	const SkYUVAInfo &	,
		const	GrBackendFormat[kMaxPlanes],
		skgpu::Mipmapped	,
		GrSurfaceOrigin
	)

Initializes a GrYUVABackendTextureInfo 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 skgpu::Mipmapped. This will produce an invalid result (return false from isValid()) if the passed formats' channels don't agree with SkYUVAInfo.

GrYUVABackendTextureInfo() [3/3]

GrYUVABackendTextureInfo::GrYUVABackendTextureInfo ( const GrYUVABackendTextureInfo &  )
