In CEP one can just use
Layer.blendMode. Howerver, UXP’s Layer doesn’t seem to provide this API. I suppose this can be done with some batchPlay, but I don’t know how.
Or more generally, how are we, plugin developers, supposed to know how to “get” properties via batchPlay? For actions like creating a layer, we can simply do it in Photoshop, then observe what
app.eventNotifier received. But sometimes I don’t want to do an action, but merely to access some properties, like the layer’s blend mode, if it’s a clipping mask, etc. Is there a general way to discover these API?
