2 * jaricom.c
3 *
4 * Developed 1997 by Guido Vollbeding.
5 * This file is part of the Independent JPEG Group's software.
6 * For conditions of distribution and use, see the accompanying README file.
7 *
8 * This file contains probability estimation tables for common use in
9 * arithmetic entropy encoding and decoding routines.
10 *
11 * This data represents Table D.2 in the JPEG spec (ISO/IEC IS 10918-1
12 * and CCITT Recommendation ITU-T T.81) and Table 24 in the JBIG spec
13 * (ISO/IEC IS 11544 and CCITT Recommendation ITU-T T.82).

20 /* The following #define specifies the packing of the four components
21 * into the compact INT32 representation.
22 * Note that this formula must match the actual arithmetic encoder
23 * and decoder implementation. The implementation has to be changed
24 * if this formula is changed.
25 * The current organization is leaned on Markus Kuhn's JBIG
26 * implementation (jbig_tab.c).
