If you want to zoom a bitmap, that is the same as stretching it. So use the StretchBlt() function. By specifying the destination coordinates to be larger than the source coordinates you will get the effect of zooming in. By making the destination coordinates smaller than the source coordinates you get the effect of zooming out. Look up
StretchBlt()(orCDC::StretchBlt()) in MSDN for more information.
