Can the user render the objects in a PDF document in a particular order?

You can draw objects from a PDF document to a window in a specific order. You could draw out of the text stream first, then a graphic, and then a vector image. For example, you might want to render the text objects in a PDF document, and leave out the images.

Use PDDrawCosObjToWindow() to draw objects smaller than a page. Generally, the object must always be a COS stream object, and must always include a Resource Dictionary. Using this method, you can draw individual objects, and image each piece. . However, like all other draw methods, this one will also clear the background on each invocation, so the objects drawn will not be cumulative.
