what about Gimp layers ?

The Gimp Layers are a stack of slides. Every layer contains a part of the image. Using layers, we can construct an image having several conceptual parts. The layers are used to manipulate a part of the image without affecting the other part.

Layers are a very important feature of GIMP and will save you a lot of precious time and effort. By using layers you protect the base image from getting altered, while still getting the look and effect you want.Sep 13, 2023

Layers are wonderful tools, especially to create collages or to delete various portions of an image. In GIMP, the layers are virtually stacked up on top of each other; the lower layers will show through resulting in a composite image that can be exported as a flat file such as a JPEG or PNG.
