Get shear boundary
| FwStatus | fwiGetShearBound | ( | FwiRect srcRoi, double bound[2][2], double xShear, double yShear, double xShift, double yShift ); |
| bound[2][2] | Boundary rectangle vertex coordinates for a transformed source ROI. | |
| srcRoi | Source image ROI. | |
| xShear | Shear value for X axis in Shear transformation. | |
| xShift | Shift value for X axis direction. | |
| yShear | Shear value for Y axis in Shear transformation. | |
| yShift | Shift value for Y axis direction. |
This function is used with the GetShearQuad function. It computes the boundaries of the source ROI for the shear functions.
Bound[0] contains the top right x and y coordinates
Bound[1] contains the bottom left x and y coordinates
