ippStsWarpDirectionErr
IPP warp functions need to know whether the transform maps source coordinates to destination coordinates or performs inverse mapping from destination pixels back to the source image. An invalid direction flag makes the mapping contract ambiguous before any pixel is processed.
Do not treat this as a bad coefficient value first. The same matrix can be legal while the selected direction enum is not supported by the called primitive or initialization routine.
Check these details
- The warp direction flag passed to the IPP initialization or execution call.
- Whether the coefficient matrix was prepared for forward or inverse mapping.
- The ROI and border policy used for destination pixels that sample outside the source image.
