image
References the image that contains the region.
xForm
RasterRegionXForm object that contains information used to translate between display coordinates and image coordinates. If you specify null in this parameter, the scalar fields default to 1, the offsets default to 0, and the view perspective defaults to the image's view perspective.
The perimeter length of the region.
Run the GetRegionPerimeterLength method on an image.
