Parameters
- m
- Type: OpenCvSharpMat
 3x3 transformation matrix.
- dsize
- Type: OpenCvSharpSize
 size of the output image.
- flags (Optional)
- Type: OpenCvSharpInterpolationFlags
 combination of interpolation methods (INTER_LINEAR or INTER_NEAREST) 
            and the optional flag WARP_INVERSE_MAP, that sets M as the inverse transformation (dst -> src).
- borderMode (Optional)
- Type: OpenCvSharpBorderTypes
 pixel extrapolation method (BORDER_CONSTANT or BORDER_REPLICATE).
- borderValue (Optional)
- Type: SystemNullableScalar
 value used in case of a constant border; by default, it equals 0.
Return Value
Type: 
Matoutput image that has the size dsize and the same type as src.
