How do you get the coordinates of the new ROI in a bitmap when you
rotate the bitmap 90 and 270 degrees?
In exact description...I have a bitmap in which there is a ROI. Now when
the bitmap rotates 90 and 270, the ROI also needs to rotate 90 and 270
degrress? Now the problem is there is a change in the window coordinates
when after I rotate 90 and 270 degrees? So simply rotating the ROI
coordinates basing on the window old center is incorrect? Or is it? I do
not know for sure. But then how do I solve this then? I have the
coordinates of the 4 ROI points that I have though based on the old
window before rotation.
