Image for RibbonButton from Resourse.resx in WPF - binding

Question

I'm work in WPF application. For global menu I use Ribbon. I need to add image to RibbonButton (LargeImageSource) from Resource.resx.
I add resource style to xaml file:
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Resources/Styles.xaml" />
</ResourceDictionary.MergedDictionaries>
Then I add my ImageConverter to xaml file:
<conv:ImageConverter x:Key="Conv" />
My C# class ImageConverter:
public class ImageConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
if (value is Bitmap)
{
var stream = new MemoryStream();
((Bitmap)value).Save(stream, ImageFormat.Png);
BitmapImage bitmap = new BitmapImage();
bitmap.BeginInit();
bitmap.StreamSource = stream;
bitmap.EndInit();
return bitmap; // use when you need normal image
var conv = new FormatConvertedBitmap();
conv.BeginInit();
conv.Source = bitmap;
conv.DestinationFormat = PixelFormats.Gray32Float;
conv.EndInit();
return conv; // use when you need grayed image
}
return value;
}
But I don't now huw Binding Image to RibbunButton:
<RibbonButton KeyTip="N"
Label="{x:Static res:Resources.New}"
LargeImageSource="{Binding Source={StaticResource res:Resources},Path=newBtn, Converter={StaticResource Conv}}"/>
But this doesn't work. What I do wrong?

Answer 1

I change XAML code for my RibbonButton:
"{Binding Source={x:Static res:Resources.newBtn}, Converter={StaticResource ImageConverter}}"
And change my ImageConverter:
public class ImageConverter: IValueConverter
{
#region IValueConverter Members
public object Convert(object value, Type targetType, object parameter,
System.Globalization.CultureInfo culture)
{
MemoryStream ms = new MemoryStream();
((System.Drawing.Bitmap)value).Save(ms, System.Drawing.Imaging.ImageFormat.Png);
BitmapImage image = new BitmapImage();
image.BeginInit();
ms.Seek(0, SeekOrigin.Begin);
image.StreamSource = ms;
image.EndInit();
return image;
}
public object ConvertBack(object value, Type targetType, object parameter,
System.Globalization.CultureInfo culture)
{
throw new NotImplementedException();
}
#endregion
}
