Retrieving Animation Timeline Data in Photoshop CS3+

[Grafalgar]

Hi all,

I have a set of photoshop files, each of which contain a number of animation frames within them.  My goal is seemingly simple - create a plugin to iterate over each frame and save specific layers to disk.  The problem is I cannot figure out how to retrieve or set the current frame of animation in code.  After a few days of digging through the SDK documentation, both online and in the SDK folder, I have failed to come up with anything concrete.

Does anyone happen to know how to retrieve/set the current frame of animation?  Or even how to determine whether or not a document has animation frames to begin with?  Any help would be *tremendously* appreciated.

I don't see a way to get any information about the animation frames. (I use the Getter plug-in to answer these types of questions.)

I did get this when setting frames from the UI. (I use the Listener plug-in to answer these types of questions.)
