Parameters

image
The source image

Return Value

A handle to the Windows DDB this method creates.

Remarks

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 does 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 DeleteObject Windows API. Otherwise, your application will leak resources.

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

For more information refer to RasterImage and GDI/GDI+.

Example

For an example, refer to FromHBitmap(IntPtr,IntPtr).
