Toucan-Tools 0.1

A simple image processing library written in python.

1-4 Performace Task

Client 4: Developer

Goal

A main script (run from terminal) processes an image with a library of image tools. Run would look something like $ toucan imagefile.jpg -t blur which would display a window showing the applied image.

Tools to start out with

• Grayscale Coloring
• Circle/polygon Packing
• Thermal Coloring
• Number Visualization (colored mosaic)

Conventions

All transformation tools are located somewhere in the tools package, and can all be called on from the root of the package. To follow the zen of python package structure: the less dots the better.
