ViewPerspective # get and set (RasterImage)
The view perspective of the image data of this RasterImage.
The view perspective indicates where the beginning of the image is stored. For more information, see RasterViewPerspective.
For more information refer to Accounting For View Perspective.
Note: You should be careful when setting the view-perspective of an image using this property since it will not change the orientation of the data of the image. To do that, use ChangeViewPerspective.
