Hello,
I'm back with my project to remove the distortions in the borders of the
screen.
I have a new idea to do better calibration easier,
1. Take a real ruler
2. make strait line
The distortion will bend the line and with the part of the line that is in
the non distorted part of the screen the correction can be done.
A friend try it on his computer with a stylus and it works fine.
I made a small video on my computer to show the idea. But on my computer I
have no stylus so I did it with the mouse :-)
These is the link to the video : https://youtu.be/pHLXzmVwp4Q
I know that my calibration tool is only a draft because
* It's coded in c++ with Qt so it cannot be added into gnome settings
* I dont use the raw data for the stylus
* I dont manage the rotation of the screen
* The graphics are ugly
* The instructions are not clear
But I hope that you guys will appreciate the idea and use it.
If some one wants to fork it into gnome setting I can help him if I have
the time to.
github repository : https://github.com/antigol/wacom-distortion
There is a file named distortion.patch that contain the patch for the
driver.
The part of the code that concern the driver did not change a lot from my
last mails : I only change the order of the polynomial from degree 3 to
degree 4.
Best regards,
Mario Geiger
