Its harder if you want to copy only a portion of the DIB or change its storage format. &nbsp; While you can do this by copying the information manually, like a complex version of the example above. &nbsp;i think the easest way would be to just copy the image from the source DIB to a memory DC using SetDIBIts() and then copy image out the memory DC to a destination DIB in the new format using GetDIBits(). &nbsp;

how can I copy the BitBlt and StretchBlt, but from a DIB to a DIB?<br />
<br />
I would like a Win32 API, but C/C++ code to manually do that would be fine, if its decently fast

Most development for the Microsoft platform is done utilizing the technologies supported by the.NET framework. Other development is done using Visual Basic for Applications (VBA) for programs like Access, Excel, Word and Outlook, with PowerShell for scripting, or with SQL for large databases.
