Сode Snippet

using (var reader = new TiffReader("TIFFWithClippingPath.tif"))
{
    const int clippingPathKey = 0x0bb7;

    if (reader.AdobeResources.Contains(clippingPathKey))
    {
        var arb = (AdobeResourceBlock)reader.AdobeResources[clippingPathKey];

        byte nameSize = arb.Data[0];

        Console.WriteLine($"Clipping path name: {System.Text.Encoding.UTF8.GetString(arb.Data.Skip(1).Take(nameSize).ToArray())}");

        // Flatness is a fixed point value in format 8p16: one byte for integer and 2 bytes for fractional.
        float flatness = (float)arb.Data[nameSize + 2] + ((float)(arb.Data[nameSize + 3] << 8 | arb.Data[nameSize + 4]) / ushort.MaxValue);

        Console.WriteLine($"Flatness: {flatness}");
    }
}
