Methods

Blit(PointD, SizeD, Graphics, PointD, RasterOperationMode, bool, PointD?, GraphicsUnit): Copy from a source Graphics to this graphics. With this method you can specify the destination coordinates and the size of area to copy which will be the same for both the source and target. If you need to apply scaling while copying, use StretchBlit(PointD, SizeD, Graphics, PointD, SizeD, RasterOperationMode, bool, PointD?, GraphicsUnit). Sizes and positions are specified in pixels.
