Scanner2web home
----------------

Scanner2web is simple web application to make your scanner available across network.

It is written in pure wsgi, and will run on any wsgi-capable server.

You just need to install it on linux or unix machine with scanner, and give other people
web address to use.

Requirements
------------

* python3, for running the scanner2web itself.
* scanimage (from sane), for interacting with scanner.
* convert (from imagemagick), for on-the-fly convertions to png.

Checking:
$ python3 --version
Should produce something like 'Python 3.4.3'

$ scanimage > image.pnm && file image.pnm
Should produce something like 'Netpbm PPM "rawbits" image data, size = ....'

$ scanimage | convert pnm:- png:image.png && file image.png
Should produce something like 'image.png: PNG image data, ...'

Installation
------------

* download all files in this repo
$ git clone <path-to-this-repo> # for example

* Run any wsgi server, with main.py as application.
If you are short on time, you can just run:

$ ./serve.py

It will host scanner2web on :8080 on all IP interfaces.
