| Код |
[ValueConversion(typeof(double), typeof(double))]
public class ScaleConverter : IValueConverter
{
#region IValueConverter Members
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
return (double)value / System.Convert.ToDouble(parameter);
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
return (double)value * System.Convert.ToDouble(parameter);
}
#endregion
}
