Currently a commandline tool to convert 2D sprite sheets to fixed versions to prevent pixel gaps in Unity.
-i/--input <file> -tw/--tileWidth <width> optional: -o/--output <file> -th/--tileHeight <height>
The input file and tile width must be specified (-i and -tw). The output flag is optional (defaults to Fixed.) and tile height flag is optional (defaults to tile width).
e.g. java -jar UnitySpritesheetFixer -i file.png -tw 32
