{
Aspose.Imaging.FileFormats.Tiff.TiffImage tiffImage = (Aspose.Imaging.FileFormats.Tiff.TiffImage)image;
// Binarize the image with a threshold value of 127.
// If a corresponding gray value of a pixel is greater than 127, a value of 255 will be assigned to it, 0 otherwise.
tiffImage.BinarizeFixed(127);
tiffImage.Save(dir + "sample.BinarizeFixed.png", new Aspose.Imaging.ImageOptions.PngOptions());
}
