The 1-bit black-and-white RasterImage used as a mask.
The action to take regarding the existing image region, if one is defined.
Creates or updates the image region by adding a region that consists of all the white pixels in a 1-bit mask image. .NET support Silverlight support WinRT support
Syntax
public void AddMaskToRegion( 
   RasterRegionXForm xform,
   RasterImage maskImage,
   RasterRegionCombineMode combineMode
)
'Declaration
 
Public Sub AddMaskToRegion( _
   ByVal xform As RasterRegionXForm, _

   ByVal combineMode As RasterRegionCombineMode _
) 
'Usage
 
Dim instance As RasterImage
Dim xform As RasterRegionXForm
Dim maskImage As RasterImage
Dim combineMode As RasterRegionCombineMode
 
instance.AddMaskToRegion(xform, maskImage, combineMode)
public void AddMaskToRegion( 
   RasterRegionXForm xform,
   RasterImage maskImage,
   RasterRegionCombineMode combineMode
)
 function Leadtools.RasterImage.AddMaskToRegion( 
   xform ,
   maskImage ,
   combineMode 
)
public:
void AddMaskToRegion( 
   RasterRegionXForm^ xform,
   RasterImage^ maskImage,
   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.
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.
