See Also 
Leadtools Namespace > RasterImage Class > AddCurveToRegion Method : AddCurveToRegion(RasterRegionXForm,RasterCurve,RasterRegionCombineMode) Method




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

Syntax

Visual Basic (Declaration) 
Public Overloads Sub AddCurveToRegion( _
   ByVal xform As RasterRegionXForm, _
   ByVal curve As RasterCurve, _
   ByVal combineMode As RasterRegionCombineMode _
) 
Visual Basic (Usage)Copy Code

public:
void AddCurveToRegion( 
   RasterRegionXForm^ xform,
   RasterCurve^ curve,

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.
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.

Example

For an example, refer to RasterCurve.

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.
