Re: [iText-questions] Help with copying a page without text

Leonard, you're advice is usually much better quality.
 
I regret you did not try the procedure I outlined before you passed judgement on it. If you had tried the procedure, I expect you would have found it works just fine for the example that was used.
 
Readers interested in the procedure outlined below, despite Leonard's advice, can consult Sid Steward's excellent Pdftk web site, www.accesspdf.com, for the inspiration for the below procedure.
 
I hasten to add the Leonard is correct about editing a PDF damaging it. That's why the Pdftk plugin for Vim is used, i.e., to repair the damaged PDF. It's not a new idea, as it's been on Sid's site since 11Feb2005, http://www.accesspdf.com/index.php?page=2.
 
Best regards,
Bill Segraves

Note that doing so will create an invalid PDF :(.

Please do NOT try to edit a PDF using text editors...
