Presentation and lecture support tool
Oppa is not PowerPoint like Application! It’s lecture and presentation support tool. It allows free drawing with basic colors over every part of screen.
Start oppa using:
$ oppa --help usage: oppa [-h] [-o] [-z] optional arguments: -h, --help show this help message and exit -o, --opaque start in opaque mode -z, --minimized start minimized
After starting oppa opens top level transparent window on which one can draw using left mouse button. Apart from drawing following actions (keys) are available: “r”, “g”, “b”, “w” change drawing color to red, green, blue and white accordingly; “e” switches to eraser mode; “space” minimizes oppa; left click on icon in tray restores minimized oppa; “t” toggles transparency and “del” erases all drawing.
Oppa currently is developed and tested on Linux using Python 2.7. It requires PyGTK and Pycairo. For drawing in transparent window composited (either using XRender or OpenGL) screen is required - oppa will complain and use only opaque mode without composited screen.
The latest stable version is available to install using pip:
$ pip install oppa
