Your example VI has IMAQ functions in it so I can't run it here at work.

Why don't you want to rotate it using IMAQ functions? Why do all the work yourself?

PS YOu can also simply set the coordinates for the IMAQ functions which allws you to specify areas of interest without even having to rotate the image.....
