Descrizione
Stile orientato agli oggetti (method):
public void CairoMatrix::scale
( float
$sx
, float $sy
)Stile procedurale:
Applies scaling by sx, sy to the transformation in the matrix. The effect of the new transformation is to first scale the coordinates by sx and sy, then apply the original transformation to the coordinates.
