public class TiffCompression
Specifies what type of compression to apply when saving page images into a TIFF file.
Examples:
Shows how to select the compression scheme to apply to a document that we convert into a TIFF image.
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
builder.insertImage(getImageDir() + "Tagged Image File Format.tiff");
// Create an "ImageSaveOptions" object which we can pass to the document's "Save" method
// to modify the way in which that method renders the document into an image.
ImageSaveOptions options = new ImageSaveOptions(SaveFormat.TIFF);
// Set the "TiffCompression" property to "TiffCompression.None" to apply no compression while saving,
// which may result in a very large output file.
// Set the "TiffCompression" property to "TiffCompression.Rle" to apply RLE compression
// Set the "TiffCompression" property to "TiffCompression.Lzw" to apply LZW compression.
// Set the "TiffCompression" property to "TiffCompression.Ccitt3" to apply CCITT3 compression.
// Set the "TiffCompression" property to "TiffCompression.Ccitt4" to apply CCITT4 compression.
options.setTiffCompression(tiffCompression);
doc.save(getArtifactsDir() + "ImageSaveOptions.TiffImageCompression.tiff", options);
