ScreenPen
Screen annotation software which allows drawing directly on the screen. It is an open source and multiplatform (all systems that support Python) alternative to tools such as Epic Pen. Supported shapes:
- line,
- rectangle,
- chart (using matplotlib).
The behavior of the program depends on the Window System you use:
- if the system supports “live transparency then a transparent background is used (you can see a video playing in the background),
- if not then the screenshot is taken, and the user draws on the captured image (you see a static image of the screen),
- sometimes your WM may be detected as not supporting “live transparency”. In that case try running with -t parameter to force it.
Usage
Installation and Execution
To run the program you need to have Python installed and execute following:
pip install screenpen
screenpen # or python -m screenpen
NOTE: Your WM may be detected as not supporting “live transparency”. In that case try running with -t parameter:
screenpen -t
Controls
- Left mouse button - drawing.
- Right mouse button - quit.
- Keyboard shortcuts:
- Ctrl + Z - undo,
