gocarlos/krop

This is a python/Qt app which can be used to crop pdf documents. Small, simple and useful. Copy of the original software Krop by Armin Straub.

Krop

Krop is a simple graphical tool to crop the pages of PDF files. It is written in Python and relies on PyQT, python-poppler-qt4 and pyPDF 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.

Disclaimer

This software was written by Armin Straub and packaged as Linux snap app by Carlos Gomes. This software is sand-boxed with the confinement strict, meaning can only access your home directory & removable media to read/write the pdf files.

Update Snap release process

The automatic build and release snapcraft is beeing updated and will require some configuration changes

https://snapcraft.io/blog/we-are-changing-the-way-you-build-snaps-from-github-repos

I wonder what is need to be tested before release and how to create these tests

clean up the snap dependencies

Can it export to PDF 1.7?

I am using my PDF's for web concent and anything less than PDF 1.7 is not usable for the web as it cannot be "streamed" (loaded in chunks). Do you plan to add this feature via Ghostscript? Speaking of Ghostscript do you plan to at least let us add custom Ghostscript code to customize the optimization? Thanks

New Krop version is available

The krop project received an update to version 0.6

https://github.com/arminstraub/krop/releases/tag/v0.6.0

Could you update the snap?

Not using the system theme

Fix this in the snapcraft.yaml file

Interface is old

I know it's based on Qt 4, so is there a way to use Oxygen theme instead of some old-fashioned theme from the late 90s?

is it possible to crop but keep the table of content?
