PROGRAM:

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
