Is there an open-source tool to view component percentages of pdf file?

Question

Adobe Acrobat optimizer has an Audit Space Usage function that displays the percentage of the file size of each type of component, e.g. images, fonts, etc. See this page for an example.

Is there an open-source tool that does the same thing?

Answer 1

I found a program that does this. It is pdfsizeopt.py from this location. I used the command

python pdfsizeopt.py --stats target.pdf

and got an output like this:

info: This is pdfsizeopt.py rUNKNOWN.
info: computing statistics for PDF: target.pdf
info: PDF size is 6805076 bytes
