Get bilinear quadrangle vertices
FwStatus | fwiGetBilinearQuad | ( | FwiRect srcRoi, double quad[4][2], const double coeffs[2][4] ); |
coeffs[2][4] | Coefficients for Warp Affine Bilinear transform. | |
quad[4][2] | Quadrangle vertex coordinates. | |
srcRoi | Source image ROI. |
This function is used with the GetBilinearBound function. It computes the vertex coordinates of the quadrangular destination ROI for the WarpBilinearQuad functions.
Quad[0] contains the top right x and y coordinates
Quad[1] contains the top left x and y coordinates
Quad[2] contains the bottom right x and y coordinates
Quad[3] contains the bottom left x and y coordinates
