This is a description of the '''SGX graphic format ''' used in [[SymbOS]] and in [[SymSee]].
A SGX graphic consists of any number of chunks, which define different picture parts. While there are limitations for the width and the height of a single part, the complete graphic can have any size, as all parts will be linked together.
