With Ed you can add various bitmap effects to your sprite sheets. This is very handy if you want to reuse the same sprites for different environments by tinting or recoloring them a bit, changing water to lava, and so on.
To add a bitmap effect to a sprite sheet, click on the three dots button in front of the sprite sheet to open the context menu, then click Bitmap Effects… to open the Bitmap Effects dialog box.
You can add multiple bitmap effects to a sprite sheet and chain effects together. To add an effect, click on the + button, and it opens a list of available effects.
You can store and load presets of effect chains by using the save and open buttons.
