Texture Atlas/Sprite Sheet

A texture atlas is a collection of images. To save space and improve efficiency, different images are usually combined onto a single large image, with a configuration file explaining how many small images make up this large image, the size of each small image, and their position on the large image.
This type of material, consisting of one or more large images and a configuration file, is called a texture atlas.
A texture atlas is also called a sprite sheet, because the English word for sprite is "sprite".
LoongBones supports importing this type of texture atlas as one kind of resource library.
