Bug ID: 400065
Summary: Features for touchscreens. Freezing annotations.
Product: okular
Version: 1.5.1
Platform: Neon Packages
OS: Linux
Status: REPORTED
Severity: wishlist
Priority: NOR
Component: general
Assignee: okular-de...@kde.org
Reporter: 842m...@gmail.com
Target Milestone: ---
I use Okular almost daily for studying course material. The annotations work
really well with a touchscreen. If I double-click an annotation tool with the
mouse it "freezes", which effectively gives me the ability to draw over pdfs
like they were printed papers.
However there are tiny but really important "tweaks" that can make Okular much
more touch-screen friendly.
1. Annotation tools can be selected by the keyboard shortcuts [1, 2, 3, ...].
However double pressing any of those keys doesn't freeze the annotation.
2. Double tapping an annotation tool through the touchscreen doesn't freeze it.
3. Adding a popup note, then typing in the note sometimes causes the pdf to
scroll for no apparent reason.
4. Inline note causes the pdf to scroll while typing in order to observe the
changes on the pdf itself. I do the pdf positioning myself so I wish I can
disable that feature.
5. Many times the pdf is rotated unintentionally while panning. I wish I can at
least disable the rotation effect or control it's sensitivity. I would rarely
need to rotate the pdf with my hands, and even if I do, I would reach out for
the menu bar.
The above features are the very most important. They first two would allow the
user to control the type of the annotation with one hand (on the keyboard) and
draw or pan with the other. Here's more touchscreen wishes below.
6. Pinching the screen to zoom is a bit jittery.
7. Sliding a finger to pan creates no momentum (or acceleration). Meaning, once
finger is released, panning stops.
My favorite pdf editor! Thanks for all the beautiful work :D
