PDF "printer" (create PDF from anything that will print - probably what
Lu Wei means above by "virtual printer") - there are several; I use
pdf995, but CutePDF is another I think. Most require ghostscript if you
haven't already got it; most (certainly pdf995) have a copy downloadable
on the same page (pdf995 will offer to get it, and does so seamlessly if
you accept, the first time you use it if you haven't got it). I presume
there's something about the licencing of ghostscript that prevents it
being integrated into the downloads, even though it is just as free as
they are. Some pdf "printer"s don't need it - I presume either their
creators have incorporated ghostscript regardless, or they've written
their own equivalent.

This isn't a good example, but shows a bit of the idea.
The first call to the tool, dumps the "objects" contained
in it, including (subset) fonts. The second call, the "extract",
extracts the numbered object. Which is object 26 in this example.
Object 35 might be the parent object.

mutool info sample.pdf

Images (6):
[Page] 1 (35 0 R): [ JPX ] 1600x1200 8bpc ICC (26 0 R)

mutool extract -r sample.pdf 26

The result is a 1600x1200 PNG file.

*******

Manual page:

https://www.mupdf.com/docs/manual-mutool-extract.html

The executable I have,

mutool --help

shows "info" as the keyword to use, whereas the documentation
page shows "show" as the keyword to display information about
a page. Presumably the keywords in the built-in help
are consistent with what actually works.

*******

I would never expect the colors to match, because
this involves computers... :-) You'll notice the info
shows "ICC" color space for the object I extracted. I don't
know if this tool makes an effort to maintain color
information or not.

Thanks for that. It installed on W7 OK.
Running, it has three stages:
Extracting images
Processing image format
Moving files to destination folder
with no progress bars. I am trying it.

Worked fine; thanks! (I'm puzzled what "Processing" it has to do; maybe
header tweaking? I did try it on a file with multiple images, and it
produced some .bmp and some .jpg, so presumably it gets the original
types.)

Hi JP Gilliver,

It has been a long time since I needed to remove all restrictions and
encryption from a PDF, where I just dug into the Usenet archives at
http://tinyurl.com/comp-text-pdf
To find this for you...

How to remove PDF permissions on Windows: (dated in December 2014)
1. Install GPL Ghostscript 9.00 for 32-bit Windows (gs900w32.exe)
http://mirror.cs.wisc.edu/pub/mirror...0/gs900w32.exe
2. Install GSview release v4.9 Win32 self extracting archive (gsv49w32.exe)
http://mirror.cs.wisc.edu/pub/mirror...m/gsv49w32.exe
3. Install ps2edit (pstoeditsetup350.exe)
http://prdownloads.sourceforge.net/p...0.exe?download
4. Bring up GSView by clicking on its shortcut
5. File-Open-protected_pdf_file.pdf
6. File-Convert (pdfwrite, 600dpi, all pages, ok)

On Linux, the thread shows this (also December 2014, so things may have
changed in the interim with the versions of software & capabilities).

To remove pdf permissions from an encrypted PDF file on Ubuntu-based Linux:

$ sudo apt-get install pdf2djvu
(That installs djvups, among other things)
$ sudo apt-get install context
(That installs ps2pdf, among other things)

$ pdf2djvu secured.pdf -o temp.djvu
$ djvups temp.djvu temp.ps
$ ps2pdf temp.ps unsecured.pdf

$ okular secure.pdf
(File Properties = Security = Encrypted)
http://i57.tinypic.com/6gwz6a.jpg
$ okular unsecure.pdf
(File Properties = Security = Unencrypted)
http://i57.tinypic.com/t899op.jpg

Note that I'm not supplying the URL because I literally had to go to the
police when I was contacted by the publisher of these documents, where the
publisher threatened me with legal action, and where I brought it all to
the police the very next day - and he stopped after they contacted him,
where I left it at that.

Note that Marek Novotny, William Unruh, Jasen Betts, Jonathan Little, Paul,
and quite a few others participated on that rather long thread, which I
only took the summary above from the beginning page on Google Groups.

Hi Paul,
We forgot to list free pdf optimization, aka shrinking the file size,
compression, making the file smaller, downsampling, whatever.

I generally use Acrobat payware to shrink, and, when the going gets rough,
I use ImageMagick (usually on Linux) or GhostScript, but your mutool
suggestion might be useful for free PDF shrinking.

Here are my logs if anyone has the need for a free PDF shrinker.
a. Test files
b. Log files

TEST FILES:
o Designing Analog Chips, by Hans Camenzind
http://designinganalogchips.com/_count/designinganalogchips.pdf
o Introduction to Programming using Python, by Y Daniel Liang
https://doc.lagout.org/programmation/python/Introduction%20to%20Programming%20using%20Python%2 0%5BLiang%202012-01-12%5D.pdf
o Building Blocks for Theoretical Computer Science, by Margaret M. Fleck
http://mfleck.cs.illinois.edu/building-blocks/version-1.3/whole-book.pdf
o Free to Choose, by Milton Friedman
http://www.proglocode.unam.mx/sites/proglocode.unam.mx/files/docencia/Milton%20y%20Rose%20Friedman%20-%20Free%20to%20Choose.pdf
o Designing automotive suspension systems
https://tinyurl.com/advanced-vehicle-technology

LOG FILES:
Usually when Adobe Acrobat fails to get a good size, ImageMagick wins:
o convert -density 200x200 -quality 60 -compress jpeg big.pdf small.pdf
o convert -density 200x200 -quality 60 -compress jpeg -resize 50% big.pdf
small.pdf
o convert -compress Zip -density 150x150 big.pdf small.pdf
o http://www.imagemagick.org/script/command-line-options.php#compress

If not, GhostScript works reasonably well on a lot of the PDFs.
o gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/ebook
-dNOPAUSE -dQUIET -dBATCH -sOutputFile=small.pdf big.pdf
o gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/screen

But each PDF is different.

In short, do you have a good free solution for resizing PDFs?

Hi Paul,
We forgot to list free pdf optimization, aka shrinking the file size,
compression, making the file smaller, downsampling, whatever.


Reprocessing PDFs for that purpose, changes the date,
creator, messes with fonts, whatever.

There's no real profit in this.

Messing with PDFs is for repurpose-ment, such as deleting
sections of no value, or removing information that doesn't
belong there. With the understanding it's a "derived"
document, and if the statistics are disturbed, it's
"document -- my_document(privatecopy)". But after
a file is repurposed, there's no need for additional
spit-polish. Job is done.

It's been a long time, since a PDF tool made such
a mess, I'd consider a pass for optimization as being
necessary. At one time, there was a big difference between
the tools, but today, from a file size perspective, and
considering the large size of rotating disk drives, this issue
is moot. I just did backups yesterday, and out of the
3TB backed up, the amount of "excess bytes" in the PDF
collection represents a "fly fart". It would be a bad
use of my time to save 10MB out of 3TB, by reprocessing
some PDF files.
