LEADTOOLS (Leadtools assembly)

AddCurveToRegion(RasterRegionXForm,RasterCurve,RasterRegionCombineMode) Method






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.
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.
The action to take regarding the existing image region, if one is defined.
Creates or updates the image region by adding a curved region. .NET support

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.
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.

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.

Example
For an example, refer to RasterCurve.
Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
