Thanks for this tool!
Sample png file is https://i.postimg.cc/66CB3w1W/ori.png
When run lsb.hide(ori.png,"hello world"),everything is ok.Open saved png with adobe photoshop, transparent area keeps well.
But lsbset.hide(ori.png,"hello world",generators.eratosthenes()) will lost the transparent area.
