Input - png buffer, number of columns

Output - array of average hsv values for each hexagon, array of centre points of hexagons, hexagon radius, number of rows

Overview

This is a module for a bigger project. It is self contained and will output to a file in the output folder. On its own it is not very useful but watch this space :)

Example

Turn this -

Into this -

[{ h: 91, s: 55, v: 21 }, {....}, .....], [[ 9.804061174918171, 16.9811320754717 ], [ ....... ], ......], 11.320754716981131
