@Name("JbData") @Properties(inherit=leptonica.class) public class JBDATA extends Pointer
 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.
