Question

Recently, I decided to play with Windows Presentation Foundation and create a variation of chess. The whole thing is kinda done (I believe) but it’s a long time now as I can’t find a way to set my PNG file as a Image control. This is exemplary class which is affected by a issue:

public class Field
{
    public Image Image { get; set; }

    public Image GetImage(String keyName)
    {
        ResourceDictionary imagesDictionary = new ResourceDictionary();
        imagesDictionary.Source = new Uri("file:/[...]/ImagesDictionary.xaml");
        var var = imagesDictionary[keyName];
        Image image = (Image) imagesDictionary[keyName];
        return image;
    }

    public void RefreshImage()
    {
        if (Unit.Subclass.CompareTo("Bishop").Equals(0))
        {
            if (Unit.Player.IsWhite)
            {
                this.Image = this.GetImage("WhiteBishop");
            }
            ...
    }

}

My ImagesDictionary.xaml file:

<ResourceDictionary>
    <ImageSource x:Key="BlackBishop">BlackBishop.png</ImageSource>
    <ImageSource x:Key="WhiteBishop">WhiteBishop.png</ImageSource>
    ...
</ResourceDictionary>

And the issue is that I don’t know how to convert the output of GetImage

(System.Windows.Media.Imaging.BitmapFrameDecode)

into the

(System.Windows.Controls.Image)

Any ideas?

Answer 1

System.Windows.Media.Imaging.BitmapFrame is derived from ImageSource.

You should be able to do this:

this.Image = new Image();
this.Image.Source = this.GetImage("WhiteBishop");

or

this.Image.Source = this.GetImage("WhiteBishop").Source;

If BitmapFrameDecode is truly derived from System.Windows.Imaging.Image, not from ImageSource.
