Adding a clipping path to tif

using (var bitmap = new Bitmap(400, 300, PixelFormat.Format24bppRgb, RgbColor.Red))
using (var path = new Aurigma.GraphicsMill.AdvancedDrawing.Path())
{
    path.DrawEllipse(0, 0, bitmap.Width, bitmap.Height);

    // 2000-2997 Clipping path information
    // http://www.adobe.com/devnet-apps/photoshop/fileformatashtml/
    const int firstPathId = 2000;

    // Inside of Adobe Resource, all points are stored in relative values to the image dimensions, so you need to provide image with/height for conversion.
    var pathData = AdobeResourceBlock.CreatePath(path, bitmap.Width, bitmap.Height);
                
    var ar = new AdobeResourceDictionary();
    ar.Add(firstPathId, new AdobeResourceBlock("MyPath", pathData));

    bitmap.Save("out.jpg", new JpegSettings() { AdobeResources = ar });
