◆ appendStages()

bool SkCoordClampShader::appendStages	(	const SkStageRec &	,
		const SkShaders::MatrixRec &
	)		const

overrideprotectedvirtual

Adds stages to implement this shader. To ensure that the correct input coords are present in r,g MatrixRec::apply() must be called (unless the shader doesn't require it's input coords). The default impl creates shadercontext and calls that (not very efficient).

Implements SkShaderBase.

        return false;
    }

    // rectangle. However, we don't mark it as such because we want the "total matrix is valid"
    // behavior in SkImageShader for filtering.

◆ flatten()

void SkCoordClampShader::flatten ( SkWriteBuffer & ) const

overrideprotectedvirtual

Override this if your subclass needs to record data that it will need to recreate itself from its CreateProc (returned by getFactory()).

DEPRECATED public : will move to protected ... use serialize() instead

Reimplemented from SkFlattenable.
