Fancy image to ASCII/ANSI converter
Project description
Image2ASCII
Converts images to ASCII, with a twist; it traces edges in the image and attempts to render them with suitably formed characters, à la good old handmade ASCII art:
It can also crop, output ANSI colour, adjust contrast/colour balance/brightness, invert, and other nice stuff, as well as render HTML.
Installation
From PyPI
# Minimal install:
pip install image2ascii
# Install with WSGI capabilities (see below):
pip install image2ascii[www]
From source
# You do use virtual envs, right?
python3 -m venv .venv
source .venv/bin/activate
# Minimal install:
pip install -e .
# Install with WSGI capabilities (see below):
pip install -e .[www]
Usage
CLI
Installation per instructions above creates an image2ascii
command; run it for more info. Play around with various combinations of --invert
, --negative
, --contrast
, --brightness
, and --color-balance
, until the results are to your liking. --color
and --crop
are also highly recommended.
WSGI
Image2ASCII can run as a simple WSGI application, courtesy of Flask. Just make sure you have installed it with the necessary extra requirements, either by running pip install image2ascii[www]
or manually installing Flask
and requests
.
For this purpose, a fully working web implementation is also included. Not only does it leverage Image2ASCII's various features, it also enables drag-and-drop and pasting of images, and includes all sovereign state flags from Wikipedia for the user to choose from. A live version is (at the time of writing) available here.
Installation via pip
will also create an image2ascii_testserver
command with an optional port number argument (default is port 8000). Use it to fire up a basic web server on localhost and try it out. (Executing wsgi.py
directly from the command line achieves the same thing.)
Here is a suggested (albeit untested) Supervisor setup:
/etc/supervisor/conf.d/image2ascii.ini
:
[program:image2ascii]
directory = /path/to/image2ascii
command = /path/to/image2ascii/.venv/bin/uwsgi --ini config.ini
/path/to/image2ascii/config.ini
:
[uwsgi]
module = image2ascii.wsgi:application
master = true
processes = 5
socket = /tmp/image2ascii.sock
chmod-socket = 666
vacuum = true
Configuration
The CLI looks for config files in these locations, by order of priority:
- Path set via
--config
parameter ~/.image2ascii
defaults.conf
in application directory (i.e. the directory whereconfig.py
is located)
The WSGI application looks for these config files, by order of priority:
web_defaults.conf
in application directory (a default one is included)~/.image2ascii
defaults.conf
in application directory
Config files follow a normal INI file structure (key=value
). For available keys, refer to config.py
(more specifically: config.Config._fields
).
Everything else
This project is totally in beta, and so its API should not be considered stable.
