Draws an image onto a canvas. The image may be optionally scaled.

«canvas» is a canvas obtained from calling the Canvas() function, or a canvas context obtained by calling the CanvasContext() function.

«image» is an image. An image can be obtained from the Pict attribute on an existing object (for an image that appears on a diagram), or as the result of calls to ReadImageFile, ReadFromURL or CanvasImage.

«x», «y»: (optional) The position where the top-left corner of the image will be placed.

«width», «height»: (optional) The final width of the pasted image (in the current context's coordinate system). When only one is specified, the aspect ratio of the image is preserved.

«swapXY»: (optional) swaps the «x» and «y» parameters. Does not cause the image to rotate.
