KDE Documentation Screenshots Requirements

• Do only use PNG.
• To give our documentation a corporate look we have decided on ONE theme/style for all screenshots:
  Window decoration: Oxygen (for kdelibs4-based apps) and Breeze (for KF5-based apps)
  Widget style: Oxygen (for kdelibs4-based apps) and Breeze (for KF5-based apps)
  Colors: KDE Default
  Background: Flat color - Color must be white
• Use Spectacle or KSnapShot, both are highly configurable.
• The screenshots should reside at the same directory level as the index.docbook file that uses them.
  Do not put them in a subdirectory.

The easiest way to achieve this (and to get default settings for applications) is to simply create a new user to get the defaults. Then run Plasma as that user when you want to take screenshots.
