rotating and zooming a graphics

I'm interested on how to make an image rotate and can also be zoom . Can anybody help me ?

Put the image into a Picture box (or an HDC.) To show it normally, just use a standard BitBlt. To rotate it, use some basic pixel manipulation to Blt it rotated. To zoom in, or out, use StretchBlt.

It this is too vague, look up some help on using BitBlt and StretchBlt
