A PDF viewer for PDF with large vector images on linux?

Question

I need to view some PDF with large vector images (they can be really large) on linux (I am on Debian Wheesy). I need also to zoom on theses images with more than 400% (infinite zoom would be great, more than 800% would be good). I have tested several PDF viewers but they have the following problems :

Evince : cannot zoom more than four or five increase of zoom ("+"), the image is so big that it doesn't even display the percentage of zoom.

Okular : cannot display the image (all is blank) after a certain degree of zoom (~70%-80%).

muPDF (last version from git and debian repository version) : cannot open a too large image. Error message : "Interger overflow" (last version) or "Out of memory" (debian version).

Xara LX : cannot import PDF in the open source version. Convert PDF to SVG for importing into Xara LX does not fit my needs because my PDF contains several pages.

Inkscape : can open PDF and its zoom is powerful, but it's not a PDF viewer so the navigation is slow.

Xournal : cannot open correctly the image (all is black).

Do you know others open source PDF viewer that could open and zoom on PDF with large vector images ?

Thank you in advance,

Both Ubuntu's Evince reader and Linux Mint's Xreader will increase their max level of zoom if their cache size is increased. You can use gsettings to view or change these settings.

Evince reader's zoom can be increased with:

gsettings set org.gnome.Evince page-cache-size 200

Xreader with:

gsettings set org.x.reader page-cache-size 200

In both cases you'll need to select an appropriate cache size in megabytes. You can first look at what your current setting's value is by instead using the gsettings get command.
