XCUtils

This is a little helper to resize @2x~ipad artwork to all required sizes using rmagick and assign names by xcode convention like @2x, ~ipad etc. On top, the output will be formatted to suit XCodes requirements for sprite atlases or xcassets. Images will be resized carefully by using the 'HammingFilter'.

Add this line to your application's Gemfile:

gem 'XCUtils'

And then execute:

$ bundle

Or install it yourself as:

$ gem install XCUtils

run

xcutils help [COMMAND]  # Describe available commands or one specific command
xcutils resize          # Resize single image or directory to all available sizes and optionally pack in xcassets or xcatlas folder
xcutils sort            # sort directory of all sizes artwork into separate image atlases per size

To ease batch tasks, there is the possibility to add a .xcutils-config into your source directory providing where you can override the default scale factors:

scale_iphone_1x       = 0.25
scale_iphone_2x       = 0.5
scale_iphone_3x       = 1.0
scale_ipad_1x         = 0.5
scale_ipad_2x         = 1.0

create_image_assets   = false
create_xcatlas        = false
dry_run               = false
