NAME

       subp2pgm - convert VobSub DVD subtitles into pgm files and xml description

SYNOPSIS

       subp2pgm [-hvf] [-o output] [-s sid] vobsub

DESCRIPTION

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

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