Assetizer

Adding images to iOS/macOS project is not straight forward. You should add 1x and/or 2x and/or 3x based on the screen size/ device. Your designer may give you the required 1x, 2x, 3x files. But what to do if they provide only one size or you downloading it from here. You should resize it with preview and rename, then add to assetcatalog. If you are continuosly adding/ changing images (especially during initial development stage), doing all these repeated tasks may become boring. Assetizer will help you to do this tasks with a single line command.

Installation

From Source

$ git clone https://github.com/jkmathew/Assetizer.git
$ cd Assetizer
$ make

With Mint

$ mint install jkmathew/Assetizer assetize

With SPM

Add following line to your Package.swift file.

dependencies: [
...,
.package(url: "https://github.com/jkmathew/Assetizer.git", .upToNextMajor(from: "0.1.0"))
]

Usage

From terminal

$ assetize image.png --size 30x30

This will create image.imageset, which can be directly used with your images.xcassets.

Additionaly you can pass following options --output - Output path, where you want to create the imageset. If you are working on a project continuously, you can set default output directory by entering,

$ defaults write me.jkmathew.assetizer outputPath /path/to/images.xcassets

if --output option not passed and no default directory set, will create imageset in the input directory.

--device - Target device family. Accepted values - [universal, iphone, ipad, watch, tv, mac]

Swift code

Import package Assetizer . Now you can use AssetWriter class like.

let writer = try AssetWriter(imagePath: "/path/to/input.png", size: CGSize(width: 30, height: 30))// you can pass CGSize.zero to take size from input.png
try writer.createAssets()

TODO

• Distribute as a package to use in SPM projects.
• Accept different device idioms.
• Create app icons.
• Specify o/p path.
• Ditribute through home brew.
• Support for linux.
