imghighlight

A tiny Python 3 wrapper to make highlighting portions of an image much easier

Installation

Installing is best done using pip:

python3 -m pip install pyhighlight

Another option is to clone the repo and copy the pyhighlight module folder (containing __init__.py) into your project directory.

Usage

The wrapper utilizes three functions:

Example

Let's say you have an image of some buildings you want to highlight:

Assuming you know the points on the image that you want to highlight, a tiny script can be written to easily generate a new image with those buildings highlighted:

import pyhighlight as ph

# Assuming we want to highlight buildings A, B, and C
# from the example image
points = {
    'A': [[45, 156], [155, 50], [156, 160]],
    'B': [[37, 253], [206, 253], [206, 276], [90, 276], [90, 297], [206, 297],
         [206, 330], [90, 330], [90, 352], [210, 352], [210, 386], [37, 386]],
    'C': [[352, 57], [518, 57], [518, 128], [410, 128], [410, 190], [352, 190]]
}

test = ph.pyhighlight('example_buildings.png')
test.highlight(points['A'])
test.highlight(points['B'], color='red', transparency=0.5)
test.highlight(points['C'], color='green')

test.save('example.png')

The final result:
