Linux                                           January 20, 2007                                     SUBP2PGM(1)

subp2pgm  converts  DVD  subtitles  from  the  VobSub  format  into an intermediate form suitable for OCR
       extraction.

       subp2pgm takes two files as input, which should be named <vobsub>.idx and <vobsub>.sub, where  vobsub  is
       the basename of the files.

       subp2pgm outputs one .pgm graphics file for each subtitle image, and a .xml description file with correct
       timing annotation, where each subtitle entry is replaced by the corresponding graphics file.

       After OCR conversion, such a file can be transformed into a proper srt file by subptools(1).  The options
       are as follows:

       -h,--help
              Display usage and quit.

       -v,--verbose
              Increase verbosity level.

       -f,--forced
              Extract forced subtitles only.

       -n,--normalize
              Normalize the palette.

       -o,--outputoutput
              Basename for all pgm output files and the xml description.

       -s,--sidsid
              Selects subtitle id from a vobsub file with several subtitle streams.  Defaults to 0.
