Printing a rectangle with exact sizes...
-
Hi all! I have to print a bar with its exact sizes. I used this code to generate a bar:
PrinterSettings ps = new PrinterSettings(); Graphics g = ps.CreateMeasurementGraphics(); IntPtr pHdc = g.GetHdc(); mf = new Metafile(pHdc, EmfType.EmfOnly); g.ReleaseHdc(pHdc); g.Dispose(); g = Graphics.FromImage(mf); g.PageUnit = GraphicsUnit.Millimeter; g.PageScale = 1; Brush b = Brushes.Black; g.FillRectangle(b, 0, 0, 2, 30); float dpix = g.DpiX; float dpiy = g.DpiY; g.Dispose(); Bitmap bm = new Bitmap(mf, (int)(mf.Width / mf.HorizontalResolution * dpix), (int)(mf.Height / mf.VerticalResolution * dpiy)); mf.Dispose();Well, when I print the bm Bitmap I obtain a big bar on my page: it isn't 2x30 mm wide, but 12x188 mm wide! Can you help me? Thanks in advantage -

For Example: Screen Res: 1024x768, Diagonal Size: 19", Pixel size: 0.377mm Screen Res: 800x600, Diagonal Size: 17", Pixel size: 0.4318mm Screen Res: 640x480, Diagonal Size: 15", Pixel size: 0.4763mm (taken from ^ [^]) So you better calculate about your display resolution. Hope that helps! Regards, Adeel
