+//TODO DEVSIX-6406: add support for indeterminate-segment-size value of dataLength
 /**
  * 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?
