changes: I changed original code to extend the possibility to generate normal image asset based on source image and 1x scale size. For instance, I have a 512x512 back.png and want to generate an image asset with 1x scale size of 44x44, execute as python generator.py --image back.png --size 44 and the script will do the rest of the work. Below is original description of the project:

AssetsGenerator

Simple Python script to generate iOS icon image assets

Install

Install Pillow first. Then clone the repo.

Usage

Run

python generator.py --icon ICON

to generate the icon assets. Replace ICON with your icon filename.

To create launch image assets run

python generator.py --launchimage IMAGE

replacing IMAGE with your @3x launch image file.
