Hi there,
Thanks Walter for your interest in this problem. I'm sure there must be quite a
few others out there using GDI+.
GDIplus comes in Microsoft Platform Core SDK so I guess it's in COFF
[http://msdn.microsoft.com/library/ ]  There are also some older "gdiplus.zip"
files on the web which have the .h,.lib and .dll files, e.g.
http://research.apiit.edu.my/gecko/ and www.codeguru.com/gdi/GDIPlus.zip which
are much easier to download.  
With COFF2OMF on gdiplus.lib the file size shrinks from 200480 to 38400 bytes.
Is that normal for COFF2OMF?
I had a go at linking the simple example below, with the following command line
and got a huge number of errors processing the headers.
While I haven't looked at these headers in detail, I can't believe there would
be simple errors in them.  
Any suggestions would be more that welcome.
Malcolm

BTW I've commented out all references to GDIPLUS except the #include <gdiplus.h>
line. If this is also commented out, it compiles, links and runs OK.
