In my case was this classic issue.

I think the answer lies at https://sourceforge.net/p/pdfsandwich/code/HEAD/tree/trunk/src/pdfsandwich.ml#l255 But I don't know enough to check.

Large file size - any way to use original images?

pdfsandwich: permissions are to restrictive, not respecting umask

It's a design feature of Tesseract. https://github.com/tesseract-ocr/tesseract/issues/1769 As most PDF viewers display transparently bitmap data under the GlyphLessFont -> the solution would be rather to fix the bug in Evince.

After some research, I found that the issue is with the current version of ghostscript (9.27). It occurs on a Mac, with ImageMagick (and ghostscript) installed via Macports. The solution is to downgrade to the prior version of Ghostscript. Here are a list of commands in case anyone can benefit from them: git clone --single-branch https://github.com/macports/macports-ports.git cd macports-ports git checkout af11993aab38d7ba77c2df895aa5ce9b405c5681 cd print/ghostscript sudo port install When asked...

Strangely enough, we don't see any specific error message from convert, only the message that it doesn't work. Do you see more if you execute the same command "manually", i.e. convert -units PixelsPerInch -type Bilevel -density 300x300 "mypdf.pdf[1]" "output.pbm" Does this work or do you see any error?

Thank you that did the trick, and your program works beautifully!

Hi, this looks like an ImageMagick problem and might be a duplicate of Bug #22: On some systems, ImageMagick has not enough permissions to deal with pdf files. You can easily fix this. Look, for instance, here: https://stackoverflow.com/questions/42928765/convertnot-authorized-aaaa-error-constitute-c-readimage-453 Does that help?

unpaper option --output-pages 2

Great to hear, although that does not solve the problem with 18.04 yet. It seems there is no other way than having the users to change the policy file manually. And even this only works if the user has admin rights.
-
The latest version distributed with Ubuntu 18.10 seems to ship with a version which does not forbid PDF handling by default. Here is a link to that version if you want to test it on your installation.
-
I don't have an idea myself but asked in the official forum.

Disable tesseract parallelization
-
Thanks for bringing this up, this is pretty awful. I don't see a way to override this policy with -limit or with an environment variable. Do you have any ideas? The only way seems to be to edit the policy.xml file manually, which would be a nuisance for occasional users.
-
Maybe you can overwrite it with an environment variable or -limit command line option. See ImageMagick architecture and search for policy.xml. I noticed that in Ubuntu 18.04 the problem is a coder policy, while in the linked commit it is a module policy. Anyway, I hope you find a way to overwrite this policy!

Maybe you can overwrite it with an environment variable or -limit command line option. See ImageMagick architecture and search for policy.xml. Note that the commit linked in the original bug description is quite new and thus documentation does not include the module policy yet.
-
I just noticed this is fixed in the latest version. This issue can be closed.

Seems that one hunk escaped... See updated, attached patch:
-
website updated
-
Please create temp dir under subdirectory
-
From version 0.1.7 on, a global temporary directory for all pdfsandwich temp files is used.
-
Unable to convert .tif (multipages .tif file) to pdf using pdfsandwich on Ubuntu
-
files put into /tmp that are world readable.
-
This has been indirectly fixed by generating a user readable temp directory which now contains all the temp files.
-
Spelling errors (patch)
-
Fixed in version 0.1.7.
-
Currently, pdfsandwich only accepts pdf files as input files. Could you convert your tiff to pdf (there should be command line utilities for this) and try it with the resulting pdf as input to pdfsandwich?

I've came up with the attached patch. Note that I'm not very familiar with OCaml, so you might want to review it throughoutly. Thanks!

-

It might also be a good idea to remove temporary files as soon as they are no longer needed (e.g. when a page is processed succesfully). Further, I have a lot of magick-xxx files staying even after successful exit.
