Example
CuviImage src, dst;
CuviStatus s = CUVI_SUCCESS;
s = src.create(ipath, CUVI_LOAD_IMAGE_COLOR);
if (s != CUVI_SUCCESS) printf("\nImage load Error: %d", s);
//Define point of rotation within image or ROI
CuviPoint2D<int> anchor(200, 0);
//Define (optional) ROI
CuviRect roi(50, 100, 200, 150);
//Perform Rotation
s = cuvi::geometryTransforms::rotate(src, dst, 1.44, anchor, roi);
cuvi::io::saveImage(dst, opath);
