public class ImageColorMode
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 an image, we can pass a SaveOptions object to
// select a color mode for the image that the saving operation will generate.
// If we set the "ImageColorMode" property to "ImageColorMode.BlackAndWhite",
// the saving operation will apply grayscale color reduction while rendering the document.
// If we set the "ImageColorMode" property to "ImageColorMode.Grayscale",
// the saving operation will render the document into a monochrome image.
// If we set the "ImageColorMode" property to "None", the saving operation will apply the default method
// and preserve all the document's colors in the output image.
