    var crop = new Crop(20, 20, bitmap.Width - 40, bitmap.Height - 40);

    var cropped = crop.Apply(bitmap);

    var clippingPath = reader.ClippingPaths[0];

    clippingPath.ApplyTransform(crop.GetPathTransformMatrix(bitmap.Width, bitmap.Height).ToGdiPlusMatrix());

    var adobeResources = new AdobeResourceDictionary();
    adobeResources.Add(FirstPathId, new AdobeResourceBlock("Apple", clippingPath.Data));

    var jpegSettings = new JpegSettings();
    jpegSettings.AdobeResources = adobeResources;
