A tool to show content details and values in a PDF file?

[mariog69599891]

I am looking for a tool that displays information about the elements inside a PDF file, and any properties the file or items may have.

I was using Acrobat / Print Production / Print Preview, but then it became apparent that InDesign was exporting PDF files that contained images of proper values, but the reported data (in Acrobat) was not correct (like a 21600 DPI image that was actually 300DPI).  My entire discussion can be seen here:

InDesign, Export to PDF with 300DPI image results in 21600DPI image?

So, are there any tools besides Acrobat that will allow me to inspect the data and elements of a PDF file, and display the information for each element?

Thanks in advance
