  • Field Details

    • OPT_BYPASS

      static final int OPT_BYPASS
      The flag bit to indicate that selective arithmetic coding bypass should be used. In this mode some of the coding passes bypass the arithmetic coder and raw bits are output. If this flag is turned on and the 'OPT_TERM_PASS' one is turned off then the any non-bypass coding pass before a bypass coding pass must use MQ termination.
      See Also:
    • OPT_RESET_MQ

      static final int OPT_RESET_MQ
      The flag bit to indicate that the MQ states for all contexts should be reset at the end of each non-bypass coding pass.
      See Also:
    • OPT_TERM_PASS

      static final int OPT_TERM_PASS
      The flag bit to indicate that regular termination should be used. When this is specified termination is performed after each coding pass. Termination is applied to both arithmetically coded and bypass (i.e. raw) passes .
      See Also:
    • OPT_VERT_STR_CAUSAL

      static final int OPT_VERT_STR_CAUSAL
      The flag bit to indicate the vertically stripe-causal context formation should be used.
      See Also:
    • OPT_PRED_TERM

      static final int OPT_PRED_TERM
      The flag bit to indicate that error resilience info is embedded on MQ termination. The predictable error-resilient MQ termination at the encoder is necessary in this case.
      See Also:
    • OPT_SEG_SYMBOLS

      static final int OPT_SEG_SYMBOLS
      The flag bit to indicate that a segmentation marker is to be inserted at the end of each normalization coding pass. The segment marker is the four symbol sequence 1010 that are sent through the MQ coder using the UNIFORM context.
      See Also:
    • MIN_CB_DIM

      static final int MIN_CB_DIM
      The minimum code-block dimension. The nominal width or height of a code-block must never be less than this. It is 4.
      See Also:
    • MAX_CB_DIM

      static final int MAX_CB_DIM
      The maximum code-block dimension. No code-block should be larger, either in width or height, than this value. It is 1024.
      See Also:
    • MAX_CB_AREA

      static final int MAX_CB_AREA
      The maximum code-block area (width x height). The surface covered by a nominal size block should never be larger than this. It is 4096
      See Also:
    • STRIPE_HEIGHT

      static final int STRIPE_HEIGHT
      The stripe height. This is the nominal value of the stripe height. It is 4.
      See Also:
    • NUM_PASSES

      static final int NUM_PASSES
      The number of coding passes per bit-plane. This is the number of passes per bit-plane. It is 3.
      See Also:
    • NUM_NON_BYPASS_MS_BP

      static final int NUM_NON_BYPASS_MS_BP
      The number of most significant bit-planes where bypass mode is not to be used, even if bypass mode is on: 4.
      See Also:
    • NUM_EMPTY_PASSES_IN_MS_BP

      static final int NUM_EMPTY_PASSES_IN_MS_BP
      The number of empty passes in the most significant bit-plane. It is 2.
      See Also:
    • FIRST_BYPASS_PASS_IDX

      static final int FIRST_BYPASS_PASS_IDX
      The index of the first "raw" pass, if bypass mode is on.
