    could you upload the pdf file you are trying to view and a screenshot of the blury representation?

    I have the problem with every pdf!

    I looked into the code and deleted these two lines in PDF_Renderer.run

    <pre>
    if self.resample != 1.:
    cr.scale(1./self.resample, 1./self.resample)
    </pre>

    Now I'm able to read text in pdf again

    It seems I don't have the ability to upload any files

    I have the problem with every pdf. Regardless if I created them or I got them from different people

    I encounter the same bug with Xubuntu 14.04.3 LTS and pdfshuffler 0.6.0

    Here is my configuration:

    $ uname -a
    Linux draco-ultrabook 3.16.0-53-generic #72~14.04.1-Ubuntu SMP Fri Nov 6 18:17:23 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

    $ apt-cache policy pdfshuffler
    pdfshuffler:
    Installed: 0.6.0-5
    Candidate: 0.6.0-5
    Version table:
    *** 0.6.0-5 0
    500 http://fr.archive.ubuntu.com/ubuntu/ trusty/universe amd64 Packages
    100 /var/lib/dpkg/status

    Please provide a fix for this bug if the above modification in PDF_Renderer.run is the clue.

    See screenshot for comparison of zoom with PDFShuffler and default PDF viewer.

    Thanks for the feedback. From what I see on the provided, screenshots, this is an expected behavior. Using a fixed resampling ratio, corresponding to a quite poor resolution was at that time a remedy for minimizing the consequences of a memory leak in python-poppler. As it has been more than two years since, I suppose most linux systems should now include a fixed version of python-poppler, so that this restriction can be removed in the next version of pdfshuffler. However I am not sure when this next version will be ready for release.
