This might be a little off-topic.

I'm sure there are several ways. My way is to obtain the pointer to
the pixels, like this:

      DIBSECTION sDibSection;

      int nBytes = ::GetObject( hBitmap
                              , sizeof( DIBSECTION )
                              , &sDibSection );

The DIBSECTION structure will host a BITMAPINFOHEADER and the mentioned pointer.
Then you can use memcpy to fill up a GIL image. For indexed images you
need to obtain the color table, also. Let me know if you are
interested in the GDI code.

Another way might be using GDI+ . This lib is easier to use than good ol' GDI.

If you have problems contact me. I can help you. I have been wading
through all the pains the GDI offers.
