# Tartarus Image Generation Tools

Command line tools for generating large sets of variations from existing image sets. 

## Installation

1. MacOS only: `xcode-select install`

1. MacOS only: `brew install libjpeg`

1. MacOS Mojave only: `export CFLAGS="-I $(xcrun --show-sdk-path)/usr/include"`

1. `python3 -m venv venv`

1. `source venv/bin/activate`

1. `pip install -r requirements.txt`

## Generating a Sample Library

```bash

python3 generator.py

    --input /path/to/input/images/and/fonts

    --output /path/to/output/images

    --output-depth 5

    --config /path/to/config.yaml

    --samples 10000

    [--show]

    [--skip-cache]

```

The input directory should contain sprites and background images in JPG or PNG format, and TTF and/or OTF fonts.

The generator script scans the input directory recursively.

An image is considered a sprite, if: 

1. it has an alpha channel with alpha of any pixel set to anything expect 'opaque'; or

2. its size is smaller than the configured 'native' size of an image

(`processor.native.size.width` and `processor.native.size.height`). 

## Generator Configuration File

Image generation is controlled by the generator configuration file. See an example in [`config/test.yaml`](config/test.yaml).
