Call startGetImageResolution(pdf, min_required_resolution) will begin the process of obtaining data on all image uses below min_required_resolution, returning the total number. So, to return all image uses, specify a very high min_required_resolution. Then, call the other functions giving a serial number 0..n - 1, to retrieve the data. Finally, call endGetImageResolution to clean up.
