g3cat - concatenate multiple g3 documents
g3cat [-l] [-a] g3-file1 ...
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
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.
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.
separate files with a one-pixel wide black line.
-h <blank lines>
specifies the number of blank lines
should prepend to each page. Default is 0.
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.
The following example will put a header line on a given g3 page, 'page1'
and put the result into 'page2':
