Detailed Description

The JbData struct holds all the data required for
the compressed jbig-type representation of a set of images.
The data can be written to file, read back, and used
to regenerate an approximate version of the original,
which differs in two ways from the original:
  (1) It uses a template image for each c.c. instead of the
      original instance, for each occurrence on each page.
  (2) It discards components with either a height or width larger
      than the maximuma, given here by the lattice dimensions
      used for storing the templates.
