Hello, since Pixelorama is made with the Godot Engine, png exporting is being handled by Godot for us, so I'm not sure if I can provide with a meaningful answer. Images are being constructed with Godot's `Image` class, which is transparent by default, so we don't do anything special to handle transparency. If you are using Godot as well, the documentation page of the `Image` class is a great help.
