# magick-tile

[![PyPi version](https://img.shields.io/pypi/v/magick-tile.svg)](https://pypi.org/project/magick-tile/)
[![pytest](https://github.com/mdlincoln/magick_tile/actions/workflows/pytest.yml/badge.svg)](https://github.com/mdlincoln/magick_tile/actions/workflows/pytest.yml)

This package and command-line utility relies on Imagemagick to efficiently create derivative tiles of a very large image, and structure them into directories compliant with [IIIF Level 0](https://iiif.io/api/image/3.0/compliance/#5-level-0-compliance) specification for static sites.

This takes inspiration heavily from https://github.com/zimeon/iiif/blob/master/iiif_static.py, but uses ImageMagick rather than Pillow in order to speed up generation at the expense of a less flexible treatment of images.

## Prerequisites

- Python > 3.9
- [Imagemagick](https://imagemagick.org/index.php) must be available on your path

## Installation

```
pip install magick-tile
```

## Run

```
 Usage: magick_tile [OPTIONS] SOURCE OUTPUT IDENTIFIER

 Efficiently create derivative tiles of a very large image, and structure them into
 directories compliant with IIIF Level 0.

```

This will create and populate the specified output directory with tiles from a given image.

N.b. because several of the Imagemagick utilities called here already utilize multiple cores, returns for running this script in parallel diminish rapidly.
