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:

/**
 * A structure class encapsulating an interval of characters expressed as an offset and count of
 * Unicode scalar values (in an IntBuffer). A <code>CharAssociation</code> is used to maintain a
 * backpointer from a glyph to one or more character intervals from which the glyph was derived.
 *
 * Each glyph in a glyph sequence is associated with a single <code>CharAssociation</code> instance.
 *
 * A <code>CharAssociation</code> instance is additionally (and optionally) used to record
 * predication information about the glyph, such as whether the glyph was produced by the
 * application of a specific substitution table or whether its position was adjusted by a specific
 * poisitioning table.
