public virtual RasterImage Realize( 
   RasterImage image
)

'Declaration
 
Public Overloads Overridable Function Realize( _
   ByVal image As RasterImage _
) As RasterImage

'Usage
 
Dim instance As AnnContainer
Dim image As RasterImage
Dim value As RasterImage
 
value = instance.Realize(image)

public:
virtual RasterImage^ Realize( 
   RasterImage^ image
)

Parameters

image: The Leadtools.RasterImage object on which to draw this AnnContainer. Must not be null (Nothing in Visual Basic).

Return Value

A Leadtools.RasterImage object that contains the combination of the original image in image overlayed with the annotation objects of this container. This is a new image with the same size as image. It is the user's responsibility to dispose this image when no longer used.

To create a Leadtools.RasterImage representation of an AnnContainer, you must first create a Leadtools.RasterImage object, fill it with the required background color and then call Realize.

Note that this method does not perform any scaling or offsetting. The container will be rendered at location 0,0 and with size equals to the container current size (ActualWidth and ActualHeight). Hence, typically, image will have the same size as the container. Otherwise, if the size of image is smaller than the container size, the returned raster image will be clipped. You can however use the image returned from this method as the source for a combine operation with another raster image to offset or scale the representation of the objects.

To render this container on the surface of a System.Windows.Media.Imaging.BitmapSource, use Realize(BitmapSource).
