Well as nothing else seems to have surfaced so
far ..
Not so sure on
genreally blindly reediting an existing PDF unmonitored, on the fly,
unless you could be very very sure of field data lengths, page shapes could
change drasitically etc .. or if you truncated data lengths you might end up
with nonsensical additions.
I have been looking at these components
PDF N MORE for for
COM
AND
PDF N MORE for
.NET is a .NET
library for generating digital
documents on the fly from any .NET application. You can use PDF N MORE
for .NET to create virtually any document in Adobe Portable
Document Format (PDF), Extensible Markup Language(XML), Hypertext Markup
Language (HTML), Microsoft Word Format (Doc), Microsoft Excel Format (XLS),
BMP, JPEG, PNG, GIF, TIFF, EMF, WMF or Exif, complete with fonts and
graphics. Other users can view your work on Microsoft� Windows, Mac� OS,
LINUX, and UNIX� platforms.
PDF N MORE for
.NET does not require any additional software other than the .NET
runtime. PDF N MORE for .NET follows the GDI+ model, thus
reducing the learning time and increasing productivity. PDF N MORE for
.NET can be used both from WinForms and WebForms (ASP.NET)
applications without any restrictions.
Using PDF N MORE for
.NET you can now give Save As option in your application to create
digital documents in PDF, XML, HTML, Doc, Excel, BMP, JPEG, PNG, GIF, TIFF,
EMF, EMF or Exif format.
PDF N MORE for .NET source code is available at extra
cost.

PDFNet is a high-quality, industry-strength PDF library meeting
requirements of the most demanding and diverse applications. Using
PDFNet you can write stand-alone, cross-platform and reliable
commercial applications that can read, write, and edit PDF documents.
PDFNet is offered on a wide range of platforms (e.g.
Windows, Mac, Linux) and programming environments (C/C++, C#, VB,
J#, and other .Net languages).
I've seen a few more USA based components for
sale but they seemed a bit expensive.
In PhP you could use a php template (by it's
self would generate your original PDF), the template holds the general nature
of the final PDF and then you would actually as you describe it "mail merge'
it back to the client.
Any kind of simplistic string replacement
you could come unstuck with the PDF's internals and any internal reference /
byte counting mechanisms in the PDF especially ifyou cause page
bleed.
If nothing else turns up
...
Freebie with sources (may need to
customise or add a feature or two for pdf) written by
T.K.Cham who did a lot of stuff on PDF and Delphi early 2000
and in 1999.
He uses an HTML like script that
then converts to PDF, could well lend itself to server applications. It would
mean designing your template PDF in Chams script like HTML with database
markers where you want the varible text in, and using simple substitution
procedures perhaps prior to converting to PDF.
A virtual mail merge if you like.
PowerPdf
"The PowerPdf is a VCL
to create PDF docment visually. Like QuickReport, you can design PDF
document easily on Delphi IDE."
Apparently there is a non-visual unit which will
even work with Kylix. That might lend itself to ASP
development.

It's source code might be useful if nedeing to

Subject: [DUG] PDF's and form
filling.
Hi,
We need to be
able to mail merge a PDF document. Anybody know of components to do
this?
Ie we have a PDF
document and we need to merge data, and produce another PDF document to send
back to the users web page.
All suggestions
welcome.
This is actually
a web server app (ASP).
Myles.
