README.md

camogen

This repository is a camouflage generator. The code is originally from Ulf Åström in PHP. You can find his applet here: http://www.happyponyland.net. I simply updated and wrote his code in Python instead of PHP.

WARNING The code only works with Python3 for the moment! WARNING

How to use

Here is a very simple example how to use the generator:

import camogen

parameters = {'width': 700, 'height': 700, 'polygon_size': 400, 'color_bleed': 0,
              'colors': ['#668F46', '#4A6B3A', '#145000', '#003022']}

image = camogen.generate(parameters)

The parameter image corresponds to the object Image from the package PIL.

Parameters

The parameters given is a python dictionary. The following parameters are mandatory:

Parameter Types Explanation
width Int Width of the image (Minimum value: 0)
height Int Height of the image (Minim value: 0)
polygon_size Int Minimum perimeter of a polygon (Minimum value: 0)
color_bleed Int Bleeding of the colors, i.e. number of neighbouring polygons with the same color (Minimum value: 0)
colors list[String] List of all the colors. Colors have to be a Hex String. (Minimum size: 1)
max_depth Int (Optional) Maximum depth for creating the polygons. (Default value: 15)

The next set of parameters adds spots on the camouflage. In the dictionary, you have to add these parameters with the key spots. If you want to add spots, all these parameters are mandatory:

Parameter Types Explanation
amount Int Number of spots (Minimum value: 0)
radius dict Dictionary with the min and max radius (Example: {'min': 0, 'max': 10}), Minimum values: 0)
sampling_variation Int Variation for the sampling, i.e. how far it goes looking for the color for the spot.

The next set of parameters pixelizes the camouflage. In the dictionary, you have to add these parameters with the key pixelize. If you want to pixelize the camouflage, all these parameters are mandatory:

Parameter Types Explanation
amount float Percentage of pixelization (Between 0 and 1)
sampling_variation Int Variation for the sampling, i.e. how far it goes looking for the color for the spot.
density dict Density of the pixels, i.e. inverse of the size of the pixels. (Example: {'x': 100, 'y': 200})

You can find examples how to generate some camouflage in the file examples.py
