ITextSharp/Pdftk: place Base64 Image from Web on PDF as Pseude-Signature
As @mkl mentioned the question is a confusing, especially the title - usually base64 and signature do not go together. Guessing you want to place a base64 image from web on the PDF as a pseudo signature?!?! A quick working example to get you started: static void Main(string[] args) {...
Modify existing PDF to add “Page N of NNN” footer
pdf,printing,ghostscript,postscript,pdftk
If you want to do this with the help of pdftk, you can do it using either the multistamp or the multibackground operation. But first you'll have to prepare a document (with the software of your choice) which creates the Page X of Y footers on empty pages (as PDF)....

You cannot modify a PDF file in a text editor and expect the file to be still compliant in general. PDF is a binary format and you need to read the PDF specification to figure out how to modify it. That said, there are heaps of places where you can...
Executing “pdftk my-pdf-form.pdf dump_data_fields” shows nothing
The problem was that the pdf was created by Adobe LiveCycle Designer and was save as "Adobe Dynamic XML From". The solution is saving the file as "Adobe Static PDF Form". Possibly pdftk cannot deal with that livecycle files.

PDFTK not working to fill out pdf form created in livecycle
There are two flavors of interactive forms in PDF: AcroForm technology: in this case the form is defined using PDF syntax. All fields have fixed coordinates. They can't change dynamically.

Getting PDFTK installed on heroku Cedar Stack for use in my app
SOLUTION: Was missing setting LD_LIBRARY_PATH in my config vars on heroku, because pdftk relies on a library file. Also, remember to tar the tar.gz to the root directory and set a PATH to /bin/pdftk. Just check out #heroku on IRC, that's where I got my answer.

How to tell what version of `pdftk` you're running?
On my WinXP (and Ubuntu) pdftk --version works just fine. e.g. Ubuntu
