resource-scaler 
A simple node utility to resize images including sprite sheets and spine animations.
Beta Features:
- Sprite sheet scaling by manipulating the data in JSON files.
- Spine scaling by manipulating the data in atlas files. JSON data is not manipulated so users need to rely on runtime scaling. More info in the below links.
Image resizing can be done using Jimp or Sharp.
