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.
+ Fixed aspect ratios, like letter size, can be chosen for selections. + 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 introduced the command line option --grid to create a grid of selections on 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. + Implemented several keyboard shortcuts including Shift+Arrow to move 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. * Remember window geometry and fit in view setting.
krop crash, if I try to open krop directly with a file. E.g. via right click menu.
in terminal it works:
krop <filename>

krop.py crashed with TypeError in main(): decode() argument 1 must be string, not None
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.
Thanks for this app this is very useful!, I have one wish: please do that the pointer mouse change when over edge icons/markers of mergin to cut, and make those markers more bigger. This would be easier when I want change the selection margins

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!
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

Thank you for the helpful suggestions! I hope you like the improved visibility of the selections and handles in the new version 0.4.8.
can you include the mainwindow.ui file to the source code ?
Added to the source files in the new version 0.4.7. Have fun!

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

Could you please try if the updated version (now 0.4.5) fixes your issue?
Waiting so long for a good pdf cropping tool. Debian Package work with Kubuntu 13.04 too.
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.

Nice suggestion! The edit-cut icon is now used in version 0.4.3.
I have a Nook 1st Generation to and I was looking for an application like this. Thank you!
