Description
Call StretchDraw to draw an image on the canvas so that it fits into the specified rectangle. StretchDraw calls the Draw method of the image. The image object determines how it will fit into the rectangle. This may involve changing magnification and/or aspect ratio.

To render the image in its natural size, use the Draw method, instead.

Images can be bitmaps, icons, or metafiles. If it is a IBitmap object, the bitmap is rendered using the value of CopyMode.
