/*

* xForm.ViewPerspective = RasterViewPerspective.TopLeft;
* image.AddRectangleToRegion(xForm, _overlayRect, RasterRegionCombineMode.Set);
*/

// such as transform the rectangle from any coordinates to another.
// 2. Use RasterImage.RectangleToImage to convert the rect from TopLeft
// to the view perspective of the image:
