About

Imagecast is like ImageMagick but for Pythonistas. Optionally provides its features via HTTP API.

Currently, this is based on Pillow. However, it might be based on Wand in the future.

There might still be dragons.

Install

Prerequisites

pip install imagecast

With service API:

pip install imagecast[service]

Features

• Colorspace conversion: monochrome, grayscale

• Cropping with negative right/bottom offsets

• Resizing while keeping aspect ratio

• Output format: Any image formats from Pillow or raw bytes

• HTTP API

Synopsis

# Display on screen
imagecast --uri="$IMGURL" --display

# Colorspace reduction to bi-level with threshold, output as bytes
imagecast --uri="$IMGURL" --monochrome=200 --format=bytes

# Colorspace reduction, cropping, resizing and format conversion
imagecast --uri="$IMGURL" --grayscale --crop=40,50,-50,-40 --width=200 --save=test.png

Example:

imagecast --uri="https://unsplash.com/photos/WvdKljW55rM/download?force=true" --monochrome=80 --crop=850,1925,-950,-900 --width=640 --display

HTTP API

Start the Imagecast service as daemon:

imagecast service

Example:

/?uri=https%3A%2F%2Funsplash.com%2Fphotos%2FWvdKljW55rM%2Fdownload%3Fforce%3Dtrue&monochrome=80&crop=850,1925,-950,-900&width=640

Note

You should not run the service without restricting the list of allowed remote hosts on the public internet.

To do that, invoke the service like:

imagecast service --allowed-hosts=unsplash.com,media.example.org
