Hello, sorry for the noob question. I'm starting to develop games and for now I'm using LibGDX as a framework. My question is that how can I unpack the images from the pack onto individual images or at least esasily generate an atlas for using them independently. I found many documentation on how to pack textures onto one single png + atlas files to use less RAM memory, but nothing about the unpacking options without atlases at all.

If we have a spritesheet with all images packed same sizes and distances is easy to split the png in equal sized llitle images, but, for instance, the Overworld.png from this pack is plenty of different sized tiles, so I don't find a nice and easy way to do it.

Thanks for your help, and apology me if i'm not asking the right question (I don't know exactly where to ask for it)
