I haven't checked, but the control which you use to display the image,
does that one offer rotation methods? The winforms
picture box control for example does that.
If not, can you use unsafe code on the compact framework? if so, you
could check my picture rotation routine here:

It might not be useful, as it's plain C# and might not work on the
CF.NET framework, but it contains the logic to rotate a
picture in 2D over any angle.
