g3cat: concatenate multiple g3 documents

NAME
       g3cat - concatenate multiple g3 documents

SYNOPSIS
       g3cat [-l] [-a] g3-file1 ...

DESCRIPTION
       g3cat  concatenates  g3  files.  These  can  either  be 'raw', that is,
       bitmaps packed according to the CCITT T.4 standard for  one-dimensional
       bitmap  encoding,  or  'digifax'  files,  created  by GNU's GhostScript
       package with the digifax drivers. Its output is a concatenation of  all
       the input files, in raw G3 format, with two white lines in between.

       If a - is given as input file, stdin is used.

       If the input data is malformed, a warning is printed to stderr, and the
       output file will have a blank line at this place.

OPTIONS
       -l     separate files with a one-pixel wide black line.

       -h <blank lines>
              specifies the number of blank lines g3cat should prepend to each
              page. Default is 0.

       -L <lines>
              limit lenght of output page to maximum <lines> lines.

SPECIAL-CASE OPTIONS
       -w <width>
              specifies  the desired page width in pixels per line. Default is
              1728 PELs, and this is mandatory if you want to send the fax  to
              a standard fax machine.  If one of the input files doesn't match
              this line width (for example because it was created by a  broken
              G3  creator),  a  warning  is  printed,  and  the  line width is
              transparently fixed.

       -a     byte-align the end-of-line codes (EOL) in the  file.  Every  EOL
              will end at a byte boundary, that is, with a  01 byte.

       -p <pad>
              specifies  a  minimum number of bytes that each output line must
              be padded to.  Padding is done with 0-bits before the EOL code.

       -R     suppress output of end-of-page code (RTC).

EXAMPLE
       The following example will put a  header  line  on  a  given  g3  page,
       'page1' and put the result into 'page2':

       echo '$header' | pbmtext | pbm2g3 | g3cat - page1 >page2
