One feature of the format is that it bridges the world of the web with the world of print very well. == Saving PDF Forms ==Annoyingly, Adobe Software does not allow you to save the contents of PDF forms using Adobe Acrobat Reader. The software tells you to print the form if you wish to have a copy. The solution is to avoid Adobe Reader (I left out the 'acrobat' since it's not even flexible -- hardly an acrobat). Okular or Evince will allow you to save the contents of that application/healthcare/insurance/DMV form that you filled out so that you have an electronic record rather than a paper record.
== PDF Tools ==
Surprisingly, I could not easily create a new PDF that was a combination of two other pdf documents. That's when I found the "PDF Toolkit" http://www.pdfhacks.com/pdftk/
OpenOffice does output pdf, and so does KPrinter, but the PDF Toolkit offers many more features that really should be present in a GUI program like Okular (formerly Kpdf ) -- which is a viewer rather than an authoring application. At least you can install the "Service Menus" into Konqueror to get some easy right-click integration. It would be interesting to use DCOP to create a simple merge GUI. PHP developers should look at the libraries and [https://www.php.net/manual/en/book.pdf.php functions] provided there for manipulating PDF forms.
PHP developers should look at == See Also == # [[Format conversion]] # see the libraries provided there [[Collections]] page for manipulating creating books which can be printed as PDF forms# The [[Cloning]] article shows an example of how the '''PDF Handler''' extension allows the wiki to generate thumbnails for pdf files as if they were regular images.
