New software! Yay? Really should complete other things first…
This program can find duplicate tiles in a 2D tile sheet. It can also remove them and save a clean version of the file. Note: Only for PNG files!
Usage is simple, just drag-and-drop a PNG file onto dtf.exe and let the program do the rest. It is a command-line driven program. There are more extensive usage instructions inside the zip if you want to write batch scripts to do lots of files, etc.
Edit: Some word-replacement bugs slipped into my release version for some reason…I fixed them and uploaded the file under the same name…I’m hoping no one has downloaded this program before I edited this message in.
Example of its power! (using graphics from a Harvest Moon GBA game)
