Description Michael Grandjean univentionstaff 2015-01-07 16:16:49 CET
A workshop attendee reported that one hits the feedback button in the PDF version of the manual quite often by accident, when reading on a touch-device. This opens the browser every time which is annoying.

In the PDF version the feedback button is at the far right and most right-handers tend to scroll in this area.

Looking at the *printed* manual, those 375 feed-back icons serve no purpose and look quiet strange.
Perhaps remove the feed-back icon from the PDF completely?

Or try <http://stackoverflow.com/questions/4717055/hide-text-in-pdf-when-printing>.

Hm… it's a pity that people are not able to click on the printed button… maybe we could print the full URI instead ;) ?

Very nice idea to hide them in the printed version :) !

Optional Content Group with Apache-FOP-2.2

Apache-FOP supports "Optional Content Groups" since version 2.2.
Debian (as of today) only has 2.1: <https://packages.debian.org/search?keywords=fop&searchon=sourcenames&exact=1&suite=all&section=all>

FOP have an example using layers: <http://svn.apache.org/viewvc/xmlgraphics/fop/trunk/fop/test/layoutengine/standard-testcases/pdf-dictionary-extension_2.xml?view=markup>

The attached file shows a minimal working example:

The layer showing the feedback icons/links can be enabled/disabled as the user sees fit (checked with KDE okular).

For printing it is disabled (checked with chromium - okular does not disable the layer by default as GhostScript from Debian-Stretch is too old; See <https://bugs.ghostscript.com/show_bug.cgi?id=696076>. With gs-9.22 from Debian-Sid it works: gs -q -dNOPAUSE -dBATCH -dPrinted -sDEVICE=pgm -sOutputFile=37473-pdf-feedback.pgm 37473-pdf-feedback.pdf)
