Possible to show total number of pages with number_pages method? #144

Is it possible to show "3 of 8" as an optional format to the number_pages method? Thanks!

Hi @leesmith

Sure it's possible. Read the documentation for CombinePDF::PDF#number_pages and consider:

filename = "foo.pdf"
pdf = CombinePDF.load filename
page_count = pdf.pages.length
number_format = "%s of #{page_count}"
pdf.number_pages number_format: number_format

Kindly, Bo.
