matrix is: The verification is based on a method similar to the preceding "panning".
The rotation of the image is slightly more complex: the corresponding point after the P0 (x0, y0) rotation theta angle is P (x, y). By using vectors, we get the following:x0 = R Cosα Y0 = r sinex = R cos (α+θ) = x0 cosθ-y0 sinθ y = r sin (α+θ) = x0 sinθ+ y0 cosθ
So we get the matrix:
What if the image rotates around a point (a, b)? Then you have to translate the coordinates to that point, rotate it, and then
