I've bought a few sets of royalty free game art, which include some tilesets I would like to used in Tiled.
Each tile has its own PNG file, way larger than I want to be using (e.g. 512x512 or 256x256). There are also object images which are not uniform dimensions.
Does anyone know if there any software that I can import all these files into, merge them into one file, and resize them all to something usable?
When searching about this I've found recommendations for TexturePacker, which I have, however it automatically arranges each image to fit in a smaller space. I just need each image to occupy a square the same size.
I could do it manually in some image software, or maybe write a script to do it, but it seems like it must be a common task and surely there's already something out there?
