In the following source code fragment a metafile is generated with a line with a length of 60 millimeter using GDI+. The problem is when I analyse this metafile with Visio or print 1:1 on paper, the dimension of the line is not 60 mm ! I hope somebody can tell me the reason. Gdiplus::GdiplusStartupInput gdiplusStartupInput; ULONG_PTR gdiplusToken; GdiplusStartup(&gdiplusToken, &gdiplusStartupInput, NULL); Metafile* myMetafile = new Metafile(L"MyDiskFile.emf", ::GetDC(NULL)); Graphics* myGraphics = new Graphics(myMetafile); Pen* myPen = new Pen(Color(255, 0, 0, 200)); myGraphics->SetPageUnit(UnitMillimeter); myGraphics->DrawLine(myPen, 0, 0, 60, 0); delete myGraphics; delete myPen; delete myMetafile; GdiplusShutdown(gdiplusToken);
