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] (https://materialdesignicons.com). 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 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.
