 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?
