Prerequisites

To be able to insert Screenshots into a Wiki page, the raw data of the lecture you want to use has to be assigned in the Electure Portal. If its not already done, please ask the maintainer of the course in the Electure Portal. You will see that its not done, when you try to select an electure and the last select in the popup (see below) has no values.

When editing an article, a toolbar will appear above the edit-field:

In this popup first select the Institute, then the semester, course (Vorlesung), chapter (Kapitel), subchapter (Unterkapitel). Then it might happen, that the last select for the recording (Aufzeichnung) is empty (see Prerequisites). If not, choose the corresponding recording from which you want to display a screenshot.

Then you you have to choose to either select the screenshot by time (Zeitpunkt) or by slide number (Foliennummer). Start and End specify the start and end time/slide for which screenshots will be generated. Additionaly you can specify the size of the screenshot (default is 720x540 pixels).
