void cairocanvas::CanvasHelper::init	(	const ::basegfx::B2ISize &	rSizePixel,

Initialize canvas helper.

This method late-initializes the canvas helper, providing it with the necessary device and size. Note that the CanvasHelper does not take ownership of the passed rDevice reference, nor does it perform any reference counting. Thus, to prevent the reference counted SpriteCanvas object from deletion, the user of this class is responsible for holding ref-counted references itself!

Parameters

rSizePixel	Size of the output surface in pixel.
rDevice	Reference device this canvas is associated with
