In RealWorld Paint, you can use most drawing and selection tools and use a feature I like to call “Layer control”, in which you can draw in front of the existing pixels, behind them, or replace them with your color or selection.
(left: paint over, middle: replace, right: paint under)
If this feature is added in Aseprite, this would save time, as of right now, doing this in Aseprite would require me to do one of these two methods:
- Put selection A over selection B and cut. Selection B would be moved lower. Paste the selection A and put selection B over selection A.
- Create 2 layers and drag the layer that goes on top, then flatten both layers.
