Yes, there are various apps which can do that, but I've asked about some api/component which can be included into application.

I once tried some of them. Most simply don't work (being printers to PDF files) and some installed nasty addware stuff. I gave up at that time.

Maybe you could try to install FinePrint (which I know works fine, but supposedly Windows-only), have it collect the print output of printed PDF files and have FinePrint print to a PDF printer.

One tool I use is GiosPDFMerge, which is open source and written in .Net but has no accessible API as far as I know.

Perhaps you could try to call pdftk using TProcess? It's open source and multi platform (at least Windows and Linux).

Thanks, I've already found pdftk as best solution atm. PowerPDF cannot do that ?

Hi,

Maybe some of them could be called via TProcess (eg: a console tool) with some parameters?

You may use Ghostscript as a console tool.

I thought pdftk was a thin wrapper around a library... "pdftk uses a slightly modified iText Java library (http://itextpdf.sourceforge.net/) to read and write PDF. The author compiled this Java library using GCJ (http://gcc.gnu.org) so it could be linked with a front end written in C++. The pdftk home page is http://www.accesspdf.com/pdftk/."

There'd probably be a problem calling the backend library, if it uses Java or C++ OO techniques, from FPC- I think somebody in the list commented on this a few days ago. I wonder whether it would be possible to modify the pdftk program to be a library with a single entry point, callable as a Pascal function?

Yes, pdftk a frontend of iText. iText is the swiss knife of PDF manipulation. Most tools related to PDF, including many PDF printers and .NET libraries use iText. It is the killer library of PDF tools.

But be careful, the license doesn't allow to use it in commercial products (that includes pdftk) http://itextpdf.com/terms-of-use/index.php. I wanted to use it and it is about 2500 eur developer license plus royalties for every copy deployed.

Nevertheless, old versions of iTextpdf (before 2010) allow something like LGPL: http://stackoverflow.com/questions/4321207/what-is-latest-version-of-itext-that-is-not-agpl http://itext-general.2136553.n4.nabble.com/Silent-license-change-td2156060.html

From this page:

Buying such a license is mandatory as soon as you develop commercial activities distributing the iText software inside your product or deploying it on a network without disclosing the source code of your own applications under the AGPL license. These activities include: offering paid services to customers as an ASP, serving PDFs on the fly in the cloud or in a web application, shipping iText with a closed source product.

In fact, I contacted with them via email and I was told that we needed to buy a license if we were going to deploy the DLL with a product. (That was too expensive for us to build a product that was just for a single client).

http://www.pdflabs.com/docs/pdftk-license/

The list of third part materials includes iText, but in the their description of the license of iText they says that is GPL, so perhaps they are using a pre-2010 version. In such case you can include pdftk for commercial use without buying a license.
