Thanks Stewart. You are correct this is one of the many GDI+ functions I have been trying to port to D. I do not have the libs but was hoping to convert them from generate them from DLLs once I am done, unless of course someone is generous enough to offer them.

The definition of the to constants are as follows:

#define GDIPCONST const
#define WINGDIPAPI __stdcall
