I've tried your code, but I get an .."undefined referenced to
_GdGetImage()..."
Probably I do not include the graphic engine properly from my application.
I just
#include <windows.h>
and link to to libmwin.a and libmwimages.a libraries,
but this doesn't suffice.
Do you known what is missing?
Thanks,
