Description Neviril 2018-09-17 19:14:27 UTC

=Background information=
Often, I need to read EPub ebooks a few meters away from my monitor and it is helpful for this to increase the default font size and type (on my configuration by default it's "Noto Sans, 10") to make text more easily readable.

=Issue encountered=
I found that changing the font size and type in EPub backend options results in Okular not updating the page number. Practically speaking, if an EPub Ebook has a 200 page count and I increase the font size, text appears to be reflowed correctly, but the page count would still remain 200. The most immediate issue is that the book gets clipped, meaning that the end could not be read if not by decreasing font size again.

Conversely, when decreasing the font size, blank pages result at the end of the document, although this is more than an annoyance than a usage-breaking bug.

=Additional notes=
Closing/reopening Okular and/or the document does not seem to solve the issue.
I observed this issue with different EPub documents.

=Backend information=
Version 0.2.3
KDE Frameworks 5.49.0
Qt 5.11.1 (built against 5.11.1)
The xcb windowing system

Document generators currently cannot inform the Okular core of a changed page count. It might be needed to reload the document.
