ToHBitmap(RasterImage,IntPtr) Method

public static IntPtr ToHBitmap( 
   RasterImage image,
   IntPtr hdc
)

'Declaration
 
Public Overloads Shared Function ToHBitmap( _
   ByVal image As RasterImage, _
   ByVal hdc As IntPtr _
) As IntPtr

'Usage
 
Dim image As RasterImage
Dim hdc As IntPtr
Dim value As IntPtr
 
value = RasterImageConverter.ToHBitmap(image, hdc)

public:
static IntPtr ToHBitmap( 
   RasterImage^ image,
   IntPtr hdc
) 

Parameters

image

The source image

hdc

Handle to the Windows device responsible for the conversion. The mapping mode of the device context must be MM_TEXT.

Return Value

Converts a Leadtools.RasterImage object into a Windows device dependent bitmap (DDB). When this method is completed, there are two copies of the image in memory: the DDB and the original Leadtools.RasterImage. Freeing one will not affect the other.

NOTE: This method returns the data in an unmanaged handle. The caller is responsible for freeing the DDB's handle when it is no longer needed using the the DeleteObject Windows API, otherwise, your application will leak resources.

For more information on DDBs and DIBs, refer to Using DIBs, DDBs, and the Clipboard.
