How can I set the layer blend mode to overlay?

I’m trying to set app.activeLayer.blendMode to “overlay” but it doesn’t seem to be working.

I’ve tried

  • app.activeLayer.blendMode = overlay
  • app.activeLayer.blendMode = Overlay
  • app.activeLayer.blendMode = OVERLAY
  • app.activeLayer.blendMode = "overlay"
  • app.activeLayer.blendMode = "Overlay"
  • app.activeLayer.blendMode = "OVERLAY"
  • app.activeLayer.blendMode(Overlay)

and so on…

Any help is appreciated!

I don’t know what you mean with app.activelayer.blendMove but right clicking>properties then choosing a layer mode is how I do it

Sure, but I’m asking about the scripting API specifically.

The available modes are in the documentation: api/ at main · aseprite/api · GitHub

You’re looking for BlendMode.OVERLAY

I found that, but I wasn’t sure if that was the syntax I should be using? Is app.activeLayer.blendMode.OVERLAY correct or am I still misunderstanding? That’s really what I’m struggling with and I can’t seem to find any examples.

It would be app.activeLayer.blendMode = BlendMode.OVERLAY, I believe. app.activeLayer.blendMode is what you’re changing the value of, and BlendMode.OVERLAY is fetching the “OVERLAY” value from an enum in the BlendMode class/namespace.


app.activeLayer.blendMode = BlendMode.OVERLAY

Ah, okay! That makes sense, I’ll give it a shot! Much appreciated
