Source

    p_options: *const *const c_char,
) -> OPJ_BOOL
Expand description

Specify extra options for the encoder. This may be called after opj_setup_encoder() and before opj_start_compress() This is the way to add new options in a fully ABI compatible way, without extending the opj_cparameters_t structure. Currently supported options are:

  • PLT=YES/NO. Defaults to NO. If set to YES, PLT marker segments, indicating the length of each packet in the tile-part header, will be written. Since 2.4.0
  • TLM=YES/NO. Defaults to NO (except for Cinema and IMF profiles). If set to YES, TLM marker segments, indicating the length of each tile-part part will be written. Since 2.4.0
  • GUARD_BITS=value. Number of guard bits in [0,7] range. Default value is 2. 1 may be used sometimes (like in SMPTE DCP Bv2.1 Application Profile for 2K images). Since 2.5.0

§Arguments

  • p_codec - Compressor handle
  • p_options - Compression options. This should be a NULL terminated array of strings. Each string is of the form KEY=VALUE.

§Returns

OPJ_TRUE in case of success.

Since 2.4.0
