Can evince pdf reader be setup to do larger zoom than 400%?

  • 772

PDF documents are usually vector graphics and can be zoomed infinitely. Some PDFs like infographics contain a lot of information and need a large zoom to read them. Why can evince not zoom over 400%? Can it be set up to do a deeper zoom?

  1. It seems an optimization in the use of memory. If the page cache size is increased, evince will allow larger zoom levels.

    This can be done from the terminal, allowing to zoom up to around 2700%, with:

    gsettings set org.gnome.Evince page-cache-size 2014

    "The maximal zoom is constrained by page cache size".

    So the maximum zoom level depends both of your page cache and the PDF itself (the heavier, the less zoom capability).
    For info, display page cache size (50 by default) with

    gsettings get org.gnome.Evince page-cache-size

    Set it to a bigger value to be able to zoom more, for instance:

    gsettings set org.gnome.Evince page-cache-size 2000
