Simple Web-based Interface for Scanner written in Python and JavaScript.

Simple Web-based Interface for Scanner

This is a simple web-based interface for scanners. It allows sharing the scanner via IP address, making it accessible by the web browser. The frontend interface allows users to crop the image and browse previously scanned images.

From a technical perspective, it is simply a SANE scanimage wrapper. There are quite many things to do to make it production (see TODO section).

Requirements

• Linux
• SANE (Scanner Access Now Easy) properly configured (scanimage tool)
• Python >= 3.8
• [Optionally] NPM (for frontend app building)

Install and run (local user)

pip install swis
swis --ip localhost --port 5520

If successfully executed visit the http://localhost:5520 (Note: http (without s))

❗IMPORTANT❗ Change the IP (localhost above) to a proper host IP address if you want to access the scanner from other computers (or other devices).

Install and run (system service)

Prerequisites

This process requires root privileges, and you need to have Python>=3.8 installed. If the root user does't have the the pip installed, you will have to install it by running the below:

• Fedora (and similar): sudo dnf install python3-pip
• Ubuntu (and similar): sudo apt-get install python3-pip

Install and start service

sudo pip3 install swis
sudo swis --ip [HOST IP ADDRESS] --port 5520 -u [USER] -g [GROUP] service install 
sudo swis service start

You can check the status by running: sudo swis service status

❗IMPORTANT❗ Change the IP ([HOST IP ADDRESS] above) to a proper host IP address, and [USER] and [GROUP] to a proper system user (owner of scanned documents).

Upgrade to new version

To upgrade swis to the new version following steps need to be performed (notice that config needs to be provided):

sudo pip install -U swis
sudo swis --ip [HOST IP ADDRESS] --port 5520 -u [USER] -g [GROUP] service install 
sudo swis service start

TODO:

• error handling
• pip package
• automatically add service with systemctl
• better user interface (i.e. image remove button)
• save as pdf, etc.
