, float $sy
) : voidEstilo procedural:
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.

Procedural only - CairoMatrix instance
sx
scale factor in the X direction
sy
scale factor in the Y direction
