Script contact sheet

Hi there,

I'm new to Bridge CC and I'm looking at helping a photographer friend streamline his time consuming manual process.

He currently has a folder containing many sub-folders which each contain 6 images.

He works his way through each sub-folder selecting all 6 images and clicking the pdf generation button on the Output panel to generate a contact sheet using a custom template including a footer and watermark.

I think I can manage looping through the folders but I'm unsure on how to start the pdf generation or apply the template and can't see anything about this in the SDK documentation.

Does anyone have any pointers? Links to useful resources or code snippets would also be great?

Thanks in advance
