Member Function Documentation

void GrShaderCaps::applyOptionsOverrides ( const GrContextOptions & options )

protected

Subclasses must call this after initialization in order to apply caps overrides requested by the client.

Note that overrides will only reduce the caps never expand them.

const PrecisionInfo& GrShaderCaps::getFloatShaderPrecisionInfo	(	GrShaderType	shaderType,
		GrSLPrecision	precision
	)		const

inline

Get the precision info for a variable of type kFloat_GrSLType, kVec2f_GrSLType, etc in a given shader type.

If the shader type is not supported or the precision level is not supported in that shader type then the returned struct will report false when supported() is called.

int GrShaderCaps::pixelLocalStorageSize ( ) const

inline

PLS storage size in bytes (0 when not supported).

The PLS spec defines a minimum size of 16 bytes whenever PLS is supported.
