I would like to use the following Win32 function in D:

GpStatus WINGDIPAPI GdipEnumerateMetafileSrcRectDestPointI(
    GpGraphics * graphics,
    GDIPCONST GpMetafile * metafile,
    GDIPCONST Point & destPoint,
    GDIPCONST Rect & srcRect,
    Unit srcUnit,
    EnumerateMetafileProc callback,
    VOID * callbackData,
    GDIPCONST GpImageAttributes * imageAttributes
);

what is the proper way to do so?

From what I can make out, the equivalent D1 declaration is probably

extern (Windows) GpStatus GdipEnumerateMetafileSrcRectDestPointI(
    GpGraphics* graphics,
    GpMetafile* metafile,
    ref Point destPoint,
    ref Rect srcRect,
    Unit srcUnit,
    EnumerateMetafileProc callback,
    void* callbackData,
    GpImageAttributes* imageAttributes
);

The equivalent D2 declaration would add a few consts here and there.

But without seeing how WINGDIPAPI and GDIPCONST are defined, I can't be sure.

Since a quick search reveals that this is a GDI+ function, I've changed the subject line to make it clearer.  I presume you have the required libs?

FYI, there is GDI+ in DWT, see dwt-win\dwt\internal\gdip\

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

I had no idea it already existed but since I've already got all structures, constants, enums, and some 600+ functions already include in my implementation, I'll see if I can complete it before I peek into DWT.

Thank you much.
