After looking for the answer in both Microsoft documentation and forums, I am at a loss. I am loading a png image as a background for an inkCanvas (WPF) which works fine, however, it always resizes the image to fit in the canvas, despite the image size..

Here was my last attempt with no success:

            BitmapImage ii = new BitmapImage(new Uri(path));
            Image img = new Image();

            img.Stretch = Stretch.None;
            img.Source = ii;
            InkCanvas1.Background = new ImageBrush(ii);

Here is what it looks like using Stretch.None and Stretch.Fill

Here is what I am trying to achieve:

Can this be done?

  • So you want imageBrush to extend beyond ink canvas? – Rohit Vats Apr 24 '14 at 16:40
  • Not necessarily, I would like the image to be aspect ratio sized to either fit max width or max height and white space on the top or bottom of the canvas (depending on landscape or portrait image). – T James Apr 24 '14 at 16:41
  • Can you post snapshot what it's like right now? And what's desired output? – Rohit Vats Apr 24 '14 at 16:45

The problem is that you're trying to set properties on an Image object that you're not using while ignoring the same settings on the ImageBrush that you are using. The Image in this case is just being thrown away and the ImageBrush just happens to be using the same source image. Set the Stretch property on the ImageBrush instead:

    BitmapImage ii = new BitmapImage(new Uri(path));

    ImageBrush imageBrush = new ImageBrush(ii);
    imageBrush.Stretch = Stretch.Uniform;
    InkCanvas1.Background = imageBrush;
