Example:

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

builder.getParagraphFormat().setStyle(doc.getStyles().get("Heading 1"));
builder.writeln("Hello world!");
builder.insertImage(getImageDir() + "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);

// The default value of this property is 128. The higher value, the darker image

doc.save(getArtifactsDir() + "ImageSaveOptions.FloydSteinbergDithering.tiff", options);
