Configure Workspace Area for Wacom Devices on Linux

Description

This script allows selecting a specific area of the screen for a Wacom device to operate only within that area. It provides options to rotate the device's orientation and define the size of the selected area based on its width or height.

Usage

Assuming you have your device already set up, connected, and also that you are using X11, install slop with the following command: Debian:

sudo apt install slop

Arch:

sudo pacman -S slop

Then clone the repository and run the script with the following command:

git clone https://github.com/kelvinauta/set_wacom_area && cd set_wacom_area

Execute the script with the following command:

./set_wacom_area.sh

Requirements

To use this script, the following tools and environments are needed:

• Wacom Device: Must be installed and configured on a Linux system. For more details on setting up Wacom on Linux, refer to the official guide: Linux Wacom Project.
• slop: A tool for selecting screen areas.
• X11: X Window System for graphical environments on Unix.

Explanation of Variables

The script uses three input variables:

1. rotate: Defines the rotation of the Wacom device. Possible values are:

   • normal (default): No rotation.
   • left: Rotation to the left (90 degrees counterclockwise).
   • right: Rotation to the right (90 degrees clockwise).
   • inverted: 180-degree rotation.

2. size_master: Defines the master dimension to calculate the workspace area based on the aspect ratio. Possible values are:

   • weight (default): Uses the selected width to calculate the height.
   • height: Uses the selected height to calculate the width.

3. wacom_id: The ID of the Wacom device. If empty, the script will list available Wacom devices and prompt the user to select one.

Aspect Ratio

The script uses a default aspect ratio of 3:2, which is common for Wacom devices. This aspect ratio can be modified directly in the script according to the user's needs.

Usage Examples

1. ./set_wacom_area.sh normal weight: Sets up the workspace area with no rotation and uses the selected width to calculate the height.

2. ./set_wacom_area.sh left height: Rotates the device 90 degrees to the left and uses the selected height to calculate the width.

3. ./set_wacom_area.sh right height: Rotates the device 90 degrees to the right and uses the selected height to calculate the width.

4. ./set_wacom_area.sh inverted weight: Rotates the device 180 degrees and uses the selected width to calculate the height.
