pack-man is a command-line tool that packs the Postscript file generated by PDFtk or Ghostscript for easier deciphering.
580.4 200 Td
( Hello )
[3.9754
0
3.9754
0
3.9754
0
3.9754
0
3.9754
0] Tj
The snippet above shows the Postscript instructions in specifying the offsets
(via Td
) and the outputting of the text Hello
(via Tj
). pack-man
compresses to an easier to decipher output as follows:
580.4 200 Td
( Hello ) [3.9754 0 3.9754 0 3.9754 0 3.9754 0 3.9754 0] Tj
While the example is contrived, pack-man's strength is amplified when the
target string to display is longer than ( Hello )
as the length of the
numbers in brackets increases.
First, generate the Postscript file
$ pdftops -paper A4 src [dest]
where src
is the name of the PDF file. You can also specify the name of
the generated Postscript file. If you omit it, pdftops
will simply
use the name of the source file with .ps
as the dest file name.
Then invoke pack-man as follows:
$ pack-man src [dest]
Where src
is the name of the generated Postscript file, and optionally
dest
is the name of the packed file, or pack-man prepend the src
file name with a .ps
extension.
Amend the packed Postscript as necessary. To convert the amended Postscript file to PDF:
$ ps2pdf src [dest]
where src
is the name of the amended Postscript file, and dest
is the
optional dest file name.
I wrote the original version in Clojure; if you refer to use that version instead, use the commit tagged 0.1.0.
