Example usage:

ih -p alpaca -s 16 -r -c 4 demo_image.png

For the demo image (source, freetoedit) using the alpaca palette, and scaling the input image x16 smaller, render the result in up to 4 colours

Open demo_image.html to see the result.

Printing

Use -g for printing. ih will:

• Use print-css functionality to ensure the print view is black+white
• Use js to dynamically split wide charts. Requires jQuery via CDN.

When printing, the page order will be legend, then a series of columns of chart.

Install from source

Using git and virtualenv:

git clone [e-mail]:glasnt/ih
cd ih
virtualenv venv
source venv/bin/activate
pip install -r requirements.txt
