[reportlab-users] Number of pages in a pdf file

I'm developing an application that uses Reportlab to output reports and 
have created a pre-viewer using wxPython that displays pages temporarily 
converted to .png using GhostScript. It is similar in effect to Acrobat 
except it isn't decorated with all the trimmings and just has page 
navigation buttons, zoom, print and save. (I can share it if anyone's 

Because the pdf has just been created, I can ask Reportlab to tell me the 
page size and number of pages but I would like to extend the functionality 
to view pdf files that have been saved in the past, so is there any way to 
retrieve this information from the pdf file itself? I guess there must be, 
because you can buy tools to do it but, *given that the files are always 
created using Reportlab*, is there a relatively simply and reliable way to 
extract this information?

With thanks for any help.
