Is there description of the numeric 'layerKind' indexes that are available through AM?

Hello! For the script to work, I need to analyze the names of the layers of the document. I get a list of all the layers through AM, then in a loop I sort them in array according to desc.getInteger (stringIDToTypeID ('layerKind')). The problem is that layerKind comes in the form of a numeric index and, in case I need to match a specific type of layer in AM with the type of a layer in DOM, and I need to understand what index it means. Is there description of the numeric 'layerKind' indexes that are available through AM?

Do you know when this index was established? This is giving me issues in CS5. It works fine in CC, but when checking the backward compatibility like explained in my other post you helped me with I am getting some errors.

Hey, that’s great!

I have extended your code to additionally include Angle, Reflected and Diamond (P.S. Your copy and paste missed a closing } bracket)
