clip()

template<typename T , typename DERIVED >

DERIVED GrPixmapBase< T, DERIVED >::clip ( SkISize  surfaceDims, SkIPoint *  surfacePt  )

inline

Map this pixmap to a rect in a surface of indicated dimensions at offset surfacePt. Clip the logical rectangle to the bounds of the surface. If the rect does not intersect the surface bounds or is empty then return a default GrPixmap. Otherwise, surfacePt is updated to refer to the upper left of the clipped rectangle. The returned pixmap will refer to the portion of the original pixmap inside the surface bounds.
