Mobile App Icon Generator (MAIG) is a bash script to generate all necessary icons for Android or iOS apps and stores
Table of Contents:
MAIG first analyze the parameters and look for the third party software it needs. If everything is correct, MAIG will check if the resolution of the original image is the minimal required for the selected platform. After that the generation will begin. When the scripts end, you can find all the generated icons in a folder called MAIG in the same location as the original image.
Example:
Path to the original image: /path/to/original/image/foo.ext
Path to the MAIG folder where generated icons will be stored: /path/to/original/image/MAIG
In the generation process, MAIG uses the identify and convert utilities for resizing the original image several times. Those utilities are included in the Image Magick software.
-A : This parameter sets MAIG as Android icon generator.
-I : This parameter sets MAIG as iOS icon generator.
-i : This parameter sets the original image.
-h : Show the help message.
maig.bash [-A|-I] -i /path/to/image/foo.ext
Example:
maig.bash -A -i /path/to/image/foo.ext : This will generate all necessary Android icons from foo.ext
maig.bash -A -i foo.ext : This will generate all necessary iOS icons from foo.ext
Android minimal resolution is 512x512 pixels (WxH).

| TVDPI | 64x64px | foo-LDPI.ext |
| XHDPI | 72x72px | foo-LDPI.ext |
| XXHDPI | 96x96px | foo-LDPI.ext |
| XXXDPI | 144x144px | foo-LDPI.ext |
| WEB | 512x512px | foo-WEB.ext |
