I am using IMAQ Construct ROI to construct a rotated Rectangle ROI. The resulting contours give coordinated of the top and bottom points of the rectangle before rotation and a fifth number indicate the angle. But can anyone tell me how can i calculate the angle in degree from this value, so that i can calculate the exact points of the rotated rectangle?
Is there any other method to find the actual coordinates of the 4 edges of the rotated rectangle? My intention is to find some points in between these edge points, which i can calculated with simple trigonometry by knowing the angle of rotation.
Thank you in advance,
Mathew
