Parameters
- xform
- RasterRegionXForm object that LEADTOOLS uses to translate between display coordinates and image coordinates. If you specify null (Nothing in Visual Basic) in this parameter, the scalar fields default to 1, the offsets default to 0, and the view perspective defaults to the image view perspective.
- rc
- A Rectangle that represents the bounding rectangle that defines the ellipse.
- combineMode
- The action to take regarding the existing image region, if one is defined.
This example will load an image, adds an elliptical region to it, run the InvertCommand to show the affected area before saving the image back to disk.
To update an existing region, you specify how the new region is to be combined with the existing one using the combineMode parameter. For more information, refer to RasterRegionCombineMode.
