Hello

Is there a Windows API function that draws and rotates a bitmap by a degree?

Thank you
Rony.

If you don't need to do this under Windows 95/98/ME, then setting the
transform may well work.

Not a single do-all function, no.  You have to move the pixels around
manually.  Read the following article for more details:

Try PlgBlt function. You can rotate and stretch the device context into any 
form.

Do note that PlgBlt() is not available on Win9x/Me.
