Return Value

A handle to the Windows DDB this method creates.

Example

For an example, refer to FromHBitmap.

Remarks

Converts a 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 RasterImage. Freeing one will not affect the other.

NOTE: This method returns the data in an unmanaged handle. The caller is repsonsible 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 Introduction.

Requirements

Target Platforms: Microsoft .NET Framework 3.0, Windows XP, Windows Server 2003 family, Windows Server 2008 family
