Generate required icon sizes and iconset from a master application icon.

appicon plugin

Getting Started

This project is a fastlane plugin. To get started with fastlane-plugin-appicon, add it to your project by running:

fastlane add_plugin appicon

Please note that this plugin uses minimagick, which requires either GraphicsMagick or ImageMagick library. If you have neither, you can install either via Homebrew:

brew install graphicsmagick

or

brew install imagemagick

The default CLI for the mini_magick gem is set to auto pick. It will first try to use GraphicsMagick (if you have it installed) otherwise it will use ImageMagick. If you want to be explicit about which CLI you use, set the minimagick_cli option to graphicsmagick or imagemagick. Not specifying this option will set MiniMagick to use auto which will choose what's available.

About appicon

Generate required icon sizes and iconset from a master application icon.

Since many apps use a single 1024x1024 icon to produce all the required sizes from, why not automate the process and save lots of time?

Example

Check out the example Fastfile to see how to use this plugin. Try it by cloning the repo, running fastlane install_plugins and bundle exec fastlane test.

Just specify the source image using the appicon_image_file. Optionally specify the devices using appicon_devices and the destination path using appicon_path.

We recommend storing the full-size picture at fastlane/metadata/app_icon.png so it can be picked up by deliver, as well as this plugin.

If you want to use this plugin to generate a app icon for Messages(sticker) extension, set messages_extension to true and add messages to the appicon_devices.
