24.3.1.1. Transform Matrix and Keystone Region Corners

The inverse transformation in the warp definition equations map the four (X,Y) corner points (0,0), (W,0), (0,H) and (W,H) to the corresponding (U,V) points (u1,v1), (u2,v2), (u3,v3) and (u4,v4) respectively.

Applying the transformation of these (X,Y) points and equating them to their corresponding (U,V) points gives the following equations. By solving these equations, the IP determines the transformation matrix values corresponding to the required mapping based on these four corners.
