See Also  Example
Leadtools Namespace > RasterImage Class > RasterImage Constructor : RasterImage Constructor(Image)



srcImage
The Image from which to create the new RasterImage.
Constructs a new RasterImage from the specified existing GDI+ Image object.

Syntax

Visual Basic (Declaration)  
Public Function New( _
   ByVal srcImage As Image _
)
Visual Basic (Usage) Copy Code
Dim srcImage As Image
 
Dim instance As RasterImage(srcImage)
C#  
public RasterImage( 
   Image srcImage
)
C++/CLI  
public:
RasterImage( 
   Image srcImage
)

Parameters

srcImage
The Image from which to create the new RasterImage.

Example

This example converts between a RasterImage and a GDI+ image.
