Exporting Layer Comps?

Hi,

I'm quite new to Photoshop plugin development, so this question might have an obvious answer, however I've been reading the SDK docs and googling around for two days without any results so I came here for help.

I'm trying to create an export plugin that exports a number of Layer Comps from a document (filtered by their names) as png files. After reading through the docs I'm left wondering if this is at all possible. The exporter example plugin in the SDK exports the current state of the document as raw data, but I've seen no indication that exporter plugins can apply or enumerate layer comps or otherwise manipulate the document state. Based on my current knowledge this would probably be possible with an automation plugin, but I don't have a good enough grasp on how those function to start experimenting with them yet.

So my questions are:

• Is it possible to use an export plugin to export several different Layer Comps? (Basically the same as the 'Layer Comps to Files' script) We'd prefer a c++ plugin for this as we'll need the plugin to interface with our current systems for which the libraries are written in c++
• If so, how would I go about doing this? The SDK documentation is pretty vague on this point.
• If not, would it be possible to do this by involving an automation plugin and if yes, how?
• If none of the above are possible, what do you suggest?

Thanks,
