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.

pts

Array of Point objects. The points in the array must be in the order in which the vertices of the polygon are connected. To create the line that closes the polygon, the last point in the array is connected to the first point of the array.

fillMode

Indicates how to handle complex crossing lines.

Value	Meaning
Winding	All pixels that are inside the resulting exterior lines are in the region.
Alternate	The region includes the area between odd-numbered and even-numbered polygon sides on each scan line.

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 RasterRegionCombineMode.

For more information, refer to Creating a Region.

For more information, refer to Saving A Region.

For more information, refer to Working with the Existing Region.
