Well an image can have an orientation. Depends on how you orient your
support (x y axis) of the image..
If you want to rotate or translate(move) your image..try a coordinate
transform where x_new = A*x_old_*(1/K) + B
here x_old is a vector of your original image coordinates
X_new = vector of new coordinates
A = rotation matrix (cosine and sine functions to rotate a point in space)
B = translation matrix
K = scaling factor (to make the image bigger or smaller)
This transform actually only effects your support so...its sort of
like orienting your image.
Try it out
