Loading Bitmap using Relative File Path

Before #2104, it is able to use the relative path for Image

<Image Width="16" Height="16" Source="Images/File.png" />

(mak sure Directory.SetCurrentDirectory(Path.GetDirectoryName(Assembly.GetEntryAssembly().Location)); first)

, where File.png is a Content that will copy to output directory. Currently, It throws a error of :

System.ArgumentException: Relative uris for 'resm' scheme aren't supported; resm:SampleApp.MainWindow.xaml?assembly=SampleApp uses resm.

However, it still is able to load the image with relative path by

Bitmap image = new Bitmap("Images/File.png");

We might add Host handling for file: scheme. So app-relative paths would look like file://appdir/Images/File.png. I think hostname in file:// is never used, so it should be fine.

Ok, I ended up with a mix of property and static resource binding. As a reference, here is my working demo code. Thanks again for the quick help!

xmlns:clr="clr-namespace:System;assembly=mscorlib"
xmlns:local="clr-namespace:MyNamespace"
...
<Window.Resources>
	<clr:String x:Key="logoPath">Graphics/StaticLogo.png</clr:String>
	<local:PathToBitmapConverter x:Key="pathToBitmapConverter"/>
</Window.Resources>
...
<Image Source="{Binding Source={StaticResource logoPath}, Converter={StaticResource pathToBitmapConverter}}"></Image>
<Image Source="{Binding DynamicImage, Converter={StaticResource pathToBitmapConverter}}"></Image>

And the converter class

public class PathToBitmapConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        string path = (string)value;

        return new Bitmap(path);
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}
