I'm using poppler from a while, I find it of high quality and very
performant also on big files, in particular the tools pdftoppm and

The question: seems to be not possible having pdfinfo tool reading the
file from the standard input, is it true ? Or I have missed something

stefano at tinvention-notebook-asus:~$ pdfinfo < Desktop/servlet-30.pdf
pdfinfo version 0.12.4

  -f <int>         : first page to convert
  -l <int>         : last page to convert
  -box             : print the page bounding boxes

Another question, the pdfinfo help report the "-f" and "- l"
parameters saying "first page to convert" , does pdfinfo convert pages
? Is it a mistake ?

Thanks in advance for the help.
