gs not found though available #45

What command do you run to optimize the PDF?

(If you see rUNKNOWN in the first few output lines, then you can help us by
downloading pdfsizeopt.py using Subversion (svn checkout). If it's easy for
you, then please do so, and run that pdfsizeopt.py again. Now you should
see the revision number instead of rUNKNOWN)

What's wrong with the optimized PDF?

There is none, because pdfsizeopt.py can't find gs. The sentence in German:
«Der Befehl "gs" ist entweder falsch geschrieben oder
konnte nicht gefunden werden.» says that Windows can not find gs.

But if I type in:

S:\XXX-2011>gs
GPL Ghostscript 9.02 (2011-03-30)
Copyright (C) 2010 Artifex Software, Inc.  All rights reserved.
This software comes with NO WARRANTY: see the file PUBLIC for details.
GS>^C
S:\XXX-2011>

-- gs works. For the record: I renamed the file gswin32c.exe to gs.exe. 

So I do not know how to proceed. I got the pdfsizeopt-Version from your SVN. 
Last week it worked beautifully; then Windows was installed newly. 

Any ideas?

Thank you,

Alexander

What should be there in the optimized PDF instead?

Thank you for submitting this bug report.

Please note that pdfsizeopt is not supported on Windows at all, so don't expect 
that it works nicely out-of-the-box -- but you may need to do some manual 
changes and workarounds.

Nevertheless, thank you for submitting the bug report, it's good to know what 
the problems are. Maybe someone will volunteer to solve them in the future.

My first suggestion would be that you should run

  python -c "import os; os.system('gs')"

If this one doesn't work, but the command

  gs

works, then this is most likely a bug or misconfiguration in your Windows or in 
your Python distribution -- and not a bug in pdfsizeopt. So please report this 
bug to whoever you got Python for Windows from.

If this simple command works, then please reply to this issue, because then 
there is a bug in pdfsizeopt.

In the meantime, you can replace gs in pdfsizeopt.py with the full path to 
gs.exe, like C:\\Program Files\\gs.exe . Please note that you might need double 
backslashes in the pathname.

Since I'm not a Windows expert, and pdfsizeopt is officially not supported

Try "gswin32c" if "gs" doesn't work. This is the console-mode version of gs.

First of all, thank you for your quick answers.

Here ist the output of the first proposal:

   python -c "import os; os.system('gs')"

gives:
   S:\XXX-2011>python -c "import os; os.system('gs')"
   GPL Ghostscript 9.02 (2011-03-30)
   Copyright (C) 2010 Artifex Software, Inc.  All rights reserved.
   This software comes with NO WARRANTY: see the file PUBLIC for details.
   GS>^CTraceback (most recent call last):
  File "<string>", line 1, in <module>
  KeyboardInterrupt

I terminated GS using Ctrl-C. And GS works:

  S:\XXX-2011>gs
  GPL Ghostscript 9.02 (2011-03-30)
  Copyright (C) 2010 Artifex Software, Inc.  All rights reserved.
  This software comes with NO WARRANTY: see the file PUBLIC for details.
  GS>^C

Could you tell me, where to replace "gs" in pdfsizeopt.py with the full path as 
you suggested? I understand your suggestion, but no python, so I failed to find 
the line doing a word search for "gs" in Emacs: it's used often.

Thanks again,

Regards,

Alexander

What does the following command print?

  python -c "import os; os.system('gs -dBATCH -dNODISPLAY')"

Does the following solve your problem? What does it print?

  python pdfsizeopt.py Beispiel.pdf

Search for GetGsCommand in pdfsizeopt.py, and modify it like this:

def GetGsCommand():
  return r'"C:\Program Files\gs.exe"'

Hey, you are fast.

   S:\XXX-2011>python -c "import os; os.system('gs -dBATCH -dNODISPLAY')"
   GPL Ghostscript 9.02 (2011-03-30)
   Copyright (C) 2010 Artifex Software, Inc.  All rights reserved.
   This software comes with NO WARRANTY: see the file PUBLIC for details.

And:

   S:\XXX-2011>python pdfsizeopt.py Beispiel.pdf
   python: can't open file 'pdfsizeopt.py': [Errno 2] No such file or directory

Then I renamed pdfsizeopt.py to pdfsizeopt-w.py and changed

   def GetGsCommand():
  """Return shell command-line prefix for running Ghostscript (gs)."""
  return r'"C:\Program Files\gs.exe"'
to

  def GetGsCommand():
  """Return shell command-line prefix for running Ghostscript (gs)."""
  return r'"C:\Programme\gs\gs9.02\bin\gswin32c.exe"'

And now it works. However, can I somewhere add the path to multivalent as well? 
Because:
   error: Multivalent.jar not found. Make sure it is on the $PATH, or it is one of
   the files on the $CLASSPATH.
   Traceback (most recent call last):
  File "C:\Programme\pdfsizeopt\pdfsizeopt-w.py", line 6953, in <module>
    main(sys.argv)
  File "C:\Programme\pdfsizeopt\pdfsizeopt-w.py", line 6945, in main
    do_generate_xref_stream=do_generate_xref_stream)
  File "C:\Programme\pdfsizeopt\pdfsizeopt-w.py", line 6701, in SaveWithMultival
  ent
    assert 0, 'Multivalent.jar not found, see above'
  AssertionError: Multivalent.jar not found, see above

Multivalent.jar is stored in the same folder like pdfsizeopt.py. 

On my Linux-machine I get other trouble, but it is often easier to find the 
source. 

Thank you for your much appreciated help,

Alexander

Thank you for the detailed bug report. Based on the information you provided I 
could identify a bug in pdfsizeopt, and I've fixed the bug in r162. (The bug 
was that pdfsizeopt always used ":" instead of os.pathsep.)

Please download the newest pdfsizeopt.py (with size 278828 bytes), rename 
gs.exe back to gswin32c.exe, and try again:

  pdfsizeopt.py Beispiel.pdf

It should work now. If it doesn't work, please reply to this issue, and include 
what it prints.

Two weeks ago I changed from MikTeX 2.9 to texlive 2010. To my surprise 
pdfsizeopt had less difficulties with pdfs produced by the latter. 

Something happend I do not understand, now: I've got two pdfsizeopt-versions:

1. pdfsizeopt-w.py, with full path to gswin32c.exe
2. pdfsizeopt.py, r163

I attach both versions of pdfsizeopt, just in case I made a mistake. My file

less similar file for upload.

Yes, the pdfsizeopt.py of size 278828 is correct.

Hmm, that's indeed strange:

So sam2p succeeds (prints `Success.'), but pdfsizeopt detects that sam2p has 
failed (status=0x1). The successful status would be 0.

In the meantime, try modifying line 5152 (`if status:') of pdfsizeop.py to:

  if status and status > 1:

This might be a workaround to your problem.

Please attach an example .pdf file which causes problems, and please attach the 
console output of pdfsizeopt.py.

In case you can fix the multivalent-error, pdfsizeopt.py would run on Windows 
XP from my point of view "out of the box". 

Wouldn't that be a good moment for a new release? 

By the way, I wrote an article about pdfsizeopt on Markus Kohms' komascript.de 
two weeks ago:
http://www.komascript.de/node/1477

I guess you understand German, don't you?

Alexander

The multivalent-error has been fixed in r164. Please retry. (You may have to 
change `if status:' to `if status and status > 1:' again.

> Wouldn't that be a good moment for a new release?

Yes it would, but I'd like to fix the sam2p issue first.

Where did you get your sam2p.exe? Could you please attach your sam2p.exe to 
this issue?

I think you have the wrong sam2p.exe, because version 0.48 has never been 
released on Windows. If you are using a 3rd party sam2p.exe, not the original 
one, that might cause problems, because the 3rd party might have introduced 
bugs (which would make the `if status:' check in pdfsizeopt fail).

To avoid further confusion, I just made a new release of sam2p (0.49). Download 
it for Windows from here:

Well, I took the version of multivalent you are offering, I tried another one 
and a third one, but all in vane, it's like there were no tools. 

This is weird. But meanwhile I'm writing a contract using Word and it is even 
stranger. 

I'm running a completly new installed Windows, by the way.

Alexander

About Multivalent: only
http://pdfsizeopt.googlecode.com/files/Multivalent20060102.jar works,
and it does contain tool/pdf/Compress . Please remove all other
Multivalent*.jar files from all of your hard drives before running
pdfsizeopt again.

Where did you get the instructions to use any other Multivalent.jar? I
think http://code.google.com/p/pdfsizeopt/wiki/InstallationInstructions
is clear where you should get Multivalent from.

Also I recommend trying pdfsizeopt on a different computer. Maybe your
computer has a bad Windows installation or a hardware defect.

The following information

  info: executing Multivalent to optimize PDF: java -cp 'C:\Programme\pdfsizeopt/Multivalent.jar' tool.pdf.Compress -nopagepiece -noalt pso.conv.mi.tmp.pdf

you have provided helped me identify and fix a bug in pdfsizeopt.py. Please 
download the newest version of pdfsizeopt.py, remove Multivalent.jar, and retry 
with Multivalent20060102.jar in the same directory as pdfsizeopt.py .

Sorry, did not wish to annoy you. The output as printed above says:

   info: executing Multivalent to optimize PDF: java -cp 'C:\Programme\pdfsizeopt/M
   ultivalent.jar' tool.pdf.Compress -nopagepiece -noalt pso.conv.mi.tmp.pdf

So it is the file "Multivalent.jar" in that directory. I've been using your 
version all the time, with the exceptions mentioned above. 

I'll try on an other machine tomorrow evening here in the office.

Alexander

Please download and try the newest pdfsizeopt.py! You can try it on any

Based on the console logs you provided in this issue I could identify and fix a 
bug in sam2p. Thank you for being patient and copying all the console outputs 
here, helping me understand and fix multiple bugs.

The newest pdfsizeopt with the newest sam2p should work for you without 
modifications. Please try again. First please remove all instances of 
pdfsizeopt.py, sam2p.exe and Multivalent.jar from your computer. Then please 
download these:

* http://sam2p.googlecode.com/files/sam2p-0.49-win32.zip
* http://pdfsizeopt.googlecode.com/files/Multivalent20060102.jar
* http://pdfsizeopt.googlecode.com/svn/trunk/pdfsizeopt.py (278997 bytes)

In the ZIP file sam2p-0.49-win32.zip please find sam2p.exe (135680 bytes) and 
extract it to next to pdfsizeopt.py 

Then run the command

  pdfsizeopt.py Beispiel2.pdf

as usual. It should succeed now. Should it fail, please attach its console 
output to this issue.

   U:\>

I integrated pdfsizeopt into my .emacs:

;; pdfsizeopt.py zur Befehlsliste
(eval-after-load "tex"
'(add-to-list 'TeX-command-list
'("pdfsizeopt" "pdfsizeopt.py %s.pdf %s.pdf" TeX-run-command t t :help "Run 
pdfsizeopt.py") t))

Using a viewer like SumatraPDF, I can compress pdfs without even closing the 
viewer. 

Regards,

Alexander
