Load image from file and print it using WPF... how?

Question

I'm looking for an example of how to load an image from file and print it on a page using WPF. I'm having a hard time finding good information about WPF printing.

Answer 1

Just load the image and apply it to a visual. Then use the PrintDialog to do the work.

...
PrintDialog printer = new PrintDialog();

if (printer.ShowDialog()) {
  printer.PrintVisual(myVisual, "A Page Title");
}

Answer 2

var bi = new BitmapImage();
bi.BeginInit();
bi.CacheOption = BitmapCacheOption.OnLoad;
bi.UriSource = new Uri("");
bi.EndInit();

var vis = new DrawingVisual();
var dc = vis.RenderOpen();
dc.DrawImage(bi, new Rect { Width = bi.Width, Height = bi.Height });
dc.Close();

var pdialog = new PrintDialog();
if (pdialog.ShowDialog() == true) {
 pdialog.PrintVisual(vis, "My Image");
}

Answer 3

If you want more control then PrintDialog.PrintVisual gives you you have to wrap your image in a FixedDocumet.

You can find simple code that creates a fixed document here: http://www.ericsink.com/wpf3d/B_Printing.html
