Extends image borders by padding extra values on the image boundaries.

Function

CuviStatus padImage(const CuviImage& src,
                    CuviImage& dst,
                    const Cuvi32s top,
                    const Cuvi32s bottom,
                    const Cuvi32s left, 
                    const Cuvi32s right,
                    const Cuvi32f* values,
                    const CuviStream& stream = CuviStream());
