Shows how to set the TIFF binarization error threshold when using the Floyd-Steinberg method to render a TIFF image.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

builder.ParagraphFormat.Style = doc.Styles["Heading 1"];
builder.Writeln("Hello world!");
builder.InsertImage(ImageDir + "Logo.jpg");

// When we save the document as a TIFF, we can pass a SaveOptions object to
// adjust the dithering that Aspose.Words will apply when rendering this image.
// The default value of the "ThresholdForFloydSteinbergDithering" property is 128.
// Higher values tend to produce darker images.
ImageSaveOptions options = new ImageSaveOptions(SaveFormat.Tiff)
    TiffCompression = TiffCompression.Ccitt3,
    TiffBinarizationMethod = ImageBinarizationMethod.FloydSteinbergDithering,
    ThresholdForFloydSteinbergDithering = 240

doc.Save(ArtifactsDir + "ImageSaveOptions.FloydSteinbergDithering.tiff", options);
