What is Retro Graphics Toolkit?
Retro Graphics Toolkit is a free software (open source) graphics converter, tilemap, blocks, chunks, sprites and level editor. The goal is to make the task of taking an image and converting it to tiles on a tilemap or sprite sheet into many sprites as easy as possible. Also easy chunk editing, block importing from an image.

Retro Graphics Toolkit is also extensible with Lua scripting support.
