Parameters
srcRoi |
Region of interest in the source image (of the IppiRect type). |
bound |
Output array. Contains vertex coordinates of the bounding rectangle for the transformed source ROI. |
coeffs |
The given affine transform coefficients. |
Description
This functionis used as a support function for WarpAffineNearest, WarpAffineLinear, and WarpAffineCubic functions. It computes vertex coordinates of the smallest bounding rectangle for the quadrangle quad, to which the source ROI is mapped by the affine transform function using coefficientscoeffs.
bound[0] specifies x, y coordinates of the top-left corner, bound[1] specifies x, y coordinates of the bottom-right corner.
Return Values
ippStsNoErr |
Indicates no error. Any other value indicates an error or a warning. |
ippStsCoeffErr |
Indicates an error condition if c00*c11 - c01*c10 = 0. |
ippStsSizeErr |
Indicates an error condition if srcRoi has a size field with zero or negative value. |
