Summary: Remove excessive whitespace when vewing
Product: okular
Version: unspecified
Platform: RedHat RPMs
OS/Version: Linux
Status: UNCONFIRMED
Severity: wishlist
Priority: NOR
Component: general
AssignedTo: okular-devel kde org
ReportedBy: kde2eran tromer org
Version: SVN (using KDE 3.5.9)
Installed from: RedHat RPMs
Many PDF files have wide margins that, while suitable for printing on paper,
are very wasteful of screen resources. This problem is especially grave with
some academic publications that use enormous margins in their standard
stylesheets.
Implications include:
* In Fit to Page zoom, wide vertical margins cause the real content of the page
to be unnecessarily small (and at other zoom levels page flipping is messy)
* In Continous mode, wide vertical margins necessitate a lot of scrolling
between pages, and you can see less content simultaneously at page borders
* In Two Pages mode, wide horizontal margins cause the real content to be
unnecessarily small (often making this important mode useless)
It would be great if Okular had an option to automatically detect margins and
to subtract them from the image, prior to calculation of zoom level and
rendering. To cover the overwhelming majority of cases, it would suffice to
just have a simple heuristic which identifies the maximal white strip at each
of the 4 edges of the paper.
