Hello,

We currently do not have any way to identify if an image is part of an optional content group. Currently the code will use the rendering engine to locate all of the images that require rendering.

You could try turning the Visible flag for all other OCG's to False and then use the ImageList functions to see if it only returns the images for the single visible layer. I believe this should work based on my understanding of the rendering code.

Andrew.
