public class JBIG2SegmentReader
- extends java.lang.Object
Class to read a JBIG2 file at a basic level: understand all the segments,
understand what segments belong to which pages, how many pages there are,
what the width and height of each page is, and global segments if there
are any. Or: the minimum required to be able to take a normal sequential
or random-access organized file, and be able to embed JBIG2 pages as images
in a PDF.
TODO: the indeterminate-segment-size value of dataLength, else?
