Description Chris Murphy 2016-06-11 19:19:08 UTC 
Description of problem:

Got a PDF that will not zoom in Document Viewer more than 75.94%.

Version-Release number of selected component (if applicable):
evince-3.20.0-1.fc24.x86_64

How reproducible:
Always with this particular PDF

Steps to Reproduce:
1. Click on the zoom field button, choose 50%, I get 50% zoom. Choose 85% and I get 75.95%. Choose 100% and I get 75.95%. Type in 150 and hit return, and it snaps back to 75.94%.
2.
3.

Actual results:

Always 75.94% zoom.

Expected results:

Arbitrary zoom should be possible.

When I download TIFF versions of the same charts from here:
https://www.faa.gov/air_traffic/flight_info/aeronav/digital_products/vfr/

And then print them to a PDF, I get a different max zoom value of 104.76% No matter what I type in or choose, it won't zoom more than 104.76%.

So different PDFs have different max zooms, but it should be possible to zoom into these PDFs a lot more than this.

OK got a pretty basic PDF I'll attach to the bug, it's just this window printed to a PDF file from Firefox. And I choose 400% and it pins itself to 390.01% max. I can't zoom in more than that. 400% is one of the preset zoom sizes (which is weirdly different for every PDF), but it won't accept 400%, it snaps to 390.01%.

Hi Chris,

the maximal zoom is constrained by page cache size so by setting higher value you should be able to get higher zoom:

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

So you're saying that, by design, intentionally, Evince cannot do a 100% zoom out of the box, which is something every other PDF viewer I've used can do on this same document, and as a result, can't properly display a significant number of PDFs? How in the world am I to take "notabug" seriously? If it's not a bug, it's bad design.
