Given a dst pixel config and a src color type what color type must the caller coax the the data into in order to use GrGpu::writePixels().

◆ surfaceSupportsReadPixels()

SurfaceReadPixelsSupport GrMockCaps::surfaceSupportsReadPixels ( const GrSurface * ) const

inlineoverridevirtual

Backends may have restrictions on what types of surfaces support GrGpu::readPixels(). We may either be able to read directly from the surface, read from a copy of the surface, or not read at all.
