What Is fop.jar? I got it from the fop-2.7-bin.zip.

fop.jar in fop-2.7-bin.zip is the JAR file for FOP 2.7, which is a print formatter driven by XSL formatting objects (XSL-FO). You can obtain fop.jar from the build folder of the fop-2.7-bin.zip file.

Below is the information about the fop.jar (2.2) file:

/**
 * <p>
 * This class represents renderer to TIFF (Tagged Image File Format) format. It
 * is one of the most popular and flexible of the current public domain raster
 * file formats, which was is primarily designed for raster data interchange.
 * Supported compression types are:
 * <ul>
 * <li>Raw noncompressed data</li>
 * <li>Byte-oriented run-length encoding "PackBits" compression.</li>
 * <li>Modified Huffman Compression (CCITT Group 3 1D facsimile compression)</li>
 * <li>CCITT T.4 bilevel compression (CCITT Group 3 2D facsimile compression)</li>
 * <li>CCITT T.6 bilevel compression (CCITT Group 4 facsimile compression)</li>
 * <li>JPEG-in-TIFF compression</li>
 * <li>DEFLATE lossless compression (also known as "Zip-in-TIFF")</li>
 * <li>LZW compression</li>
 * </ul>
 * This class actually does not render itself, instead it extends
 * <code>org.apache.fop.render.java2D.Java2DRenderer</code> and just encode
 * rendering results into TIFF format using Batik's image codec
