Creo already currently does this when it creates a color PDF. It creates temporary images in the working directly and then deletes them. Currently I have to create a PDF and then export the PDF back to an image. Alterantively I can quickly copy the images as they are being created in the working directory.
Rather than rely on these work arounds, expose the functionaily so that users can use the funcationality directly. The code for making the images is already there.
