WPF - converting Bitmap to ImageSource

Question

I need to convert a System.Drawing.Bitmap into System.Windows.Media.ImageSource class in order to bind it into a HeaderImage control of a WizardPag

I do not believe that ImageSourceConverter will convert from a System.Drawing.Bitmap. However, you can use the following:

public static BitmapSource CreateBitmapSourceFromGdiBitmap(Bitmap bitmap)
{
    if (bitmap == null)
        throw new ArgumentNullException("bitmap");

    var rect = new Rectangle(0, 0, bitmap.Width, bitmap.Height);

    var bitmapData = bitmap.LockBits(
        rect,
        ImageLockMode.ReadWrite,
        PixelFormat.Format32bppArgb);

    try
    {
        var size = (rect.Width * rect.Height) * 4;

        return BitmapSource.Create(
            bitmap.Width,
            bitmap.Height,
            bitmap.HorizontalResolution,
            bitmap.VerticalResolution,
            PixelFormats.Bgra32,
            null,
            bitmapData.Scan0,
            size,
            bitmapData.Stride);
    }
    finally
    {
        bitmap.UnlockBits(bitmapData);
    }
}

This solution requires the source image to be in Bgra32 format; if you are dealing with other formats, you may need to add a conversion.
