scale_artworks

TL;DR - create @2x and @1x versions for filename@3x.png in current folder

This script looks for @3x.png files in the directory you're running it from, and makes @2x and @1x versions automatically.

You can place the script into your /usr/bin to run it like scale_artworks.swift; otherwise specify full/relative path to script e.g. ./scale_artworks.swift. You can also freely remove .swift extension.

Usage:

In terminal, cd to folder with artworks and run scale_artworks.swift or copy the script to the folder and run ./scale_artworks.swift

make_icons

TL;DR - provide app icon in 1024x1024 and get all the other resolutions

This tiny script can save you a great deal of time creating AppIcon.appiconset icons for your iOS app. Just run the script in your console and it will automatically create icons in all resolutions that you can use in your Xcode iOS project.

You can place the script into your /usr/bin to run it like make_icons.swift; otherwise specify full/relative path to script e.g. ./make_icons.swift. You can also freely remove .swift extension.

Usage:

make_icons.swift <icon_name(s)> where icon_name is relative or full path to the file

for Mac app icons supply -mac param like so: make_icons.swift -mac <icon_name(s)>

Demo of updating all your app icon sizes in less then a minute (.gif, 4.5mb)

Instruction to populate your AppIcon.appiconset

1. Manually copy generated icon files from make_icons output folder to .appiconset folder
2. Replace contents of Contents.json with contents of sampleContents.json or sampleContents macos.json and all the icons would be picked up by xcode, no need for dragging and dropping each one individually
3. Enjoy :)
