Pixel Counter

---

Just a small script that counts the total amount of pixels. We use it in http://aerolab.co/culture <3

Usage as Module

npm install pixelcounter --save

var pixelCounter = require('pixelcounter');
console.log(pixelCounter.availableFormats());
pixelCounter.start(directory, scanFormats, showProgress, onEnd);

availableFormats(): Will return avaiable image extensions to count

start(directory, formats, showProgress, onEnd): Will start the process of counting pixels in a certain directory.

• It requires a directory, where to scan images.
• An array of formats, if null it will scan all formats.
• A callback for each time a image is counted. It will return filename, amount of pixels in file, total pixels counted at the moment.
• A callback when the process finishes counting. It returns the amount of pixels.

For an example implementation you can read cli.js

Usage of CLI

We built in a small example to use it as cli (besides beeing a npm package)

First of all... download dependencies.

npm install

Second step.. COUNT!

node cli.js

By default it will get all images (with compatible extension) in current folder but you can set some custom parameters.

The following options are supported:

  -d, --dir <ARG1>      Directory
  -f, --formats <ARG1>  Image extensions separated with comma
  --bmp                 Count any bmp file
  --gif                 Count any gif file
  --jpg                 Count any jpg file
  --jpeg                Count any jpeg file
  --png                 Count any png file
  --psd                 Count any psd file
  --tiff                Count any tiff file
  --webp                Count any webp file
  --svg                 Count any svg file
