Determine if incoming PDF has bitmap within?

Hi -

I'm trying to create a user option whereby the OCR'ing of a incoming PDF can be skipped if the PDF
does not contain any BITMAPs.

In other words, and incoming PDF that is all text would be skipped.

Is there a way, using any part of the Tracker library, to determine if the incoming PDF contains
a bitmap?

The only way I can see is to analyze content of every page (or less precise method - just to analyze resources used by page's content and descendant XForm and annotations) of incoming document.
New Core API SDK (or Editor SDK) can be used for that.
