public static void AddGeometryToRegion(RasterImage image,RasterRegionXForm xform,Geometry geometry,RasterRegionCombineMode combineMode)
image
The source image.
xform
Leadtools.RasterRegionXForm object that LEADTOOLS uses to translate between display coordinates and image coordinates. If you specify null (Nothing in VB) in this parameter, the scalar fields default to 1, the offsets default to 0, and the view perspective defaults to the image view perspective.
geometry
The WPF geometry to add.
combineMode
The action to take regarding the existing image region, if one is defined.
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 Leadtools.RasterRegionCombineMode.
