Acrobat PDF interactive forms generated with CL-PDF

This page demonstrates the usage of AcroForms using CL-PDF. The links on this page point to files to download:

README contains the license and the same information as this web page
some necessary additional functions are defined in pt.lisp (that file contains test expressions as comments)
an example of a PDF form (272766 bytes) where depending on the user input (max 55 char, no validation), a 2D barcode is drawn (it should be compliant with the PDF417 norm, I used pdf417decode [a SourceForge project whose exact URL I don't remember] to check it for several string inputs). Note that the implementation of the PDF417 only accepts ASCII characters between #\Space and (code-char 127) [bounds included] and encodes those in a naive way. This is a kind of teaser: I did NOT include the code necessary to draw the 2D barcode because the example is not usable enough (too slow) and the code is too ugly.
I haven't tested an HTTP/mail submit
My PERSONAL INTERPRETATION of the docs at adobe.com is that AcroForms will not be developed further, but its successor: XFA (XML Forms Architecture). I found the AcroForms approach easier to begin with so that's what I did, but the usefulness of this code might be limited
