public static void CropRegionToQuadrangle ( AvlNet.Region inRegion, AvlNet.Path inQuadrangle, AvlNet.Size? inOutputSize, AvlNet.CoordinateSystem2D? inQuadrangleAlignment, AvlNet.Region outRegion, AvlNet.Path outAlignedShape )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inRegion | AvlNet.Region | Input region. | |||
inQuadrangle | AvlNet.Path | A convex quadrangle defining a region to be cropped (points must be clockwise). | |||
inOutputSize | AvlNet.Size? | Width and height of the output region. Default value: atl::NIL. | |||
