This script provides an easy way to generate from a high def png all the icons requested for mobile development (16, 29, 32, 36, 40, 48, 50, 57, 58, 60, 64, 72, 76, 80, 87, 96, 100, 114, 120, 128, 144, 152, 167, 180, 192, 256, 512, 1024).

Add your high def icon in the script directory. Then can generate icons in two ways:

• via your local browser, example via MAMP: http://localhost:8888/IconsCreator/resizor.php
• using a CLI: cd in the script directory then php resizor.php myHighDefIcon.png

On OS X Yosemite, you need to run export PATH=/usr/local/php5/bin:$PATHbefore using the CLI.
