Parameters

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 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 Using DIBs, DDBs, and the Clipboard.

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