public virtual BitmapSource Realize( 
   BitmapSource source
)

'Declaration
 
Public Overloads Overridable Function Realize( _
   ByVal source As BitmapSource _
) As BitmapSource

'Usage
 
Dim instance As AnnContainer
Dim source As BitmapSource
Dim value As BitmapSource
 
value = instance.Realize(source)

public:
virtual BitmapSource^ Realize( 
   BitmapSource^ source
)

Parameters

source: The System.Windows.Media.Imaging.BitmapSource object on which to draw this AnnContainer. Must not be null (Nothing in Visual Basic).

Return Value

A System.Windows.Media.Imaging.BitmapSource object that contains the combination of the original source in source overlayed with the annotation objects of this container. This is a new bitmap source with the same size as source.

To create a System.Windows.Media.Imaging.BitmapSource representation of an AnnContainer, you must first create a System.Windows.Media.Imaging.BitmapSource 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, source will have the same size as the container. Otherwise, if the size of source is smaller than the container size, the returned bitmap source will be clipped. You can however use the bitmap source returned from this method as the source for a combine operation with another bitmap source to offset or scale the representation of the objects.

To render this container on the surface of a LEADTOOLS Leadtools.RasterImage, use Realize(RasterImage).
