xrandr-keystone-helper

This programm helps finding the parameters for xrandr --transform. Helpfull for e.g. keystone-correction for projektors.

Transformed pictures with "xrandr --tranform" may (very likely) still have some issues espacially around the cursor. The result could sufficide for viewing movies or presenting slides.

Dependencies: python 3 numpy matplotlib

execute: $python xrandr-keystone-helper.py

adjust the red tetragon/quadrilateral and test the result until you find the right parameters. The string to use with xrandr --transform gets printed to the terminal.

To get the Testbutton working change eDP1 to the output you want to configure e.g. VGA1.
