Declaration
procedure DrawToCanvas(DestCanvas: TCanvas; xDst, yDst : integer);
Description
Draws the whole bitmap to the specified
DestCanvas canvas, at coordinates
xDst, yDst.
Note:
◼This is a simplified version of
RenderToCanvas
◼Note: If
DrawToCanvas is used with an image with an alpha channel,
the image will be modified. Use
DrawToCanvasWithAlpha if the source bitmap has an alpha channel that should be respected when drawing.
