Description:

krop is a simple graphical tool to crop the pages of PDF files.

It is written in Python and relies on PyQT, python-poppler-qt5 and PyPDF2 for its functionality. A unique feature of krop is its ability to automatically split pages into subpages to fit the limited screen size of devices such as eReaders. This is particularly useful, if your eReader does not support convenient scrolling.

For more information and how to install krop, see: http://arminstraub.com/software/krop

krop (0.6.0) 2020-06-09 -- Armin Straub 5 months ago

+ Selections (or a grid of selections) for the full page can now be created
using the context menu or by pressing Insert (or Shift+Insert). Also

the initial page.
+ Auto trimming margins can now inspect all pages.
+ New option for whether to include pages without selections in the output.
+ Added the command line options --optimize (thanks to Ondrej Tichacek for
suggesting this feature) and --exceptions.

current selection and Delete to remove it.
* Keep track of current selection and highlight it visually.
* Don't fail on PDFs that are encrypted with an empty password.

Thanks for the report!

The following should fix the crash: in krop.py, replace the line
fileName = args.file.decode(sys.stdin.encoding)
with
fileName = args.file.decode(sys.stdin.encoding or sys.getdefaultencoding())
Please let me know if this does not work as intended.

This change will be included in the next update of krop.

The last line of your output suggests that popplerqt4 is not correctly setup on your system. Try typing "from popplerqt4 import Poppler" at a python command line to see if you get an error.

Not sure what may have caused the problem; does the suggestion at https://groups.google.com/forum/#!topic/frescobaldi/ViHxQpW4470 make sense to you?

Hi, thanks for this little nifty program, works very well.

I also have the bug which prevents Krop to be used via the right-clivk "open with" menu.

Three more suggestions in order of importance:
1) Provide a way to allow to crop many different pdf files with the same cropping geometry/selection. Or at least speed up the process. (eg: option to remember output folder and cropping region for the next file, and button to open the next file in the working folder)

2)Provide a button to automatically select a region without having to do it manually. Okular does have such a button that says "trim margins".

3)Krop seems to forget, if closed and reopened, the last opened files and their folder.

Thank you!

Version 0.4.6 now has your item (2) covered, but I have not yet gotten around to items (1) and (3).

Thank you for the comments! I like your suggestions and plan to address them in the next version (which will probably be a few weeks down the road of time).

In Kubuntu 12.04, i can't open files using the "Open" button in the GUI - opening the same files using the terminal (krop file.pdf) works great. Here's the error thats shown when I start krop in the terminal and try to open a file:

UnicodeEncodeError: 'ascii' codec can't encode character u'\xe4' in position 26: ordinal not in range(128)

Great program, thanks a lot!!!

Note, command line option [file] doesn't work on Kubuntu.

e.g.: krop /home/user/Dokumente/test.pdf

krop: Unexpected argument '/home/user/Dokumente/test.pdf'.
krop: Use --help to get a list of available command line options.

Thanks for the kind words!
The bug you mention will be fixed in the next version.
(To fix this silly regression right now you can replace the line 'KCmdLineArgs.init (sys.argv, aboutData)' in krop.py by the line 'KCmdLineArgs.init(aboutData)'.)

Thanks,

KCmdLineArgs.init(aboutData) fixes the command line problem in Kubuntu.

context menu "open with->krop" now work too in Dolphin.

Note, krop has no icon in Kubuntu. Perhaps you can use this system icon:
Icon=edit-cut
