Before calling this function, you must declare an RGNXFORM structure and set its values, which LEADTOOLS uses to translate between device context coordinates and bitmap coordinates. For details about how the structure works refer to the RGNXFORM structure description. For a description of common usage, refer to Translating Coordinates for a Bitmap Region.
The default settings for the region transform are:
the Scalar fields default to 1.
the Offset fields default to 0.
the View Perspective field defaults to the associated class objects bitmap view perspective.
Win32, x64.
For an example, refer to LBitmapRgn::SetRgnPolygon.
