Summary
Creates or updates the image region by adding a region that consists of all the white pixels in a 1-bit mask image.
Syntax
public void AddMaskToRegion(Leadtools.RasterRegionXForm xform,Leadtools.RasterImage maskImage,Leadtools.RasterRegionCombineMode combineMode)
Public Sub AddMaskToRegion( _ByVal xform As Leadtools.RasterRegionXForm, _ByVal maskImage As Leadtools.RasterImage, _ByVal combineMode As Leadtools.RasterRegionCombineMode _)
public void AddMaskToRegion(Leadtools.RasterRegionXForm xform,Leadtools.RasterImage maskImage,Leadtools.RasterRegionCombineMode combineMode)

public void addMaskToRegion(RasterRegionXForm xform,RasterImage maskImage,RasterRegionCombineMode combineMode)
function Leadtools.RasterImage.AddMaskToRegion(xform ,maskImage ,combineMode)
public:void AddMaskToRegion(Leadtools.RasterRegionXForm^ xform,Leadtools.RasterImage^ maskImage,Leadtools.RasterRegionCombineMode combineMode)
Parameters
xform
RasterRegionXForm object that LEADTOOLS uses to translate between display coordinates and image coordinates.
maskImage
The 1-bit black-and-white RasterImage used as a mask.
combineMode
The action to take regarding the existing image region, if one is defined.
