Summary

Creates or updates the image region by adding a curved region.

Syntax

C#
VB
Java
C++
Public Overloads Sub AddCurveToRegion( _ 
   ByVal xform As Leadtools.RasterRegionXForm, _ 
   ByVal curve As Leadtools.RasterCurve, _ 
   ByVal combineMode As Leadtools.RasterRegionCombineMode _ 
)  
public void addCurveToRegion( 
  RasterRegionXForm xform,  
  RasterCurve curve,  
  RasterRegionCombineMode combineMode 
) 
             

Parameters

xform
RasterRegionXForm object that LEADTOOLS uses to translate between display coordinates and image coordinates. If you specify null in this parameter, the scalar fields default to 1, the offsets default to 0, and the view perspective defaults to the image view perspective.

curve
A RasterCurve object that specifies the curve region. You specify the curve using device context coordinates, and LEADTOOLS translates the coordinates using the values specified in the xform.

combineMode
The action to take regarding the existing image region, if one is defined.

Remarks

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.
