How can I programmatically convert RTF documents to PDF?
OpenOffice.org can be run in server mode (i.e. without any GUI), can read RTF files and can output PDF files.
You have a number of options depending on:
the platform(s) your application will be running on
whether your application will be a server application (e.g. a web service that you set up once and then it runs), or a widely-available desktop application (e.g. something that must be easily downloadable and installable by many people)
whether you are willing to put little or more programming effort into getting the solution to work
whether you are flexible as to the programming language you will use
Here are some options:
PDFCreator + COM
Windows only
suitable for both desktop and server applications
medium programming effort
any language that allows you to speak COM
OpenOffice ( + JODConverter - optional )
Cross-platform (Windows, Linux, etc.)
suitable for server applications, as OpenOffice is a 100MB+ download
low programming effort
Java (if using JODConverter), or any language that can interface with OpenOffice's UNO
IText + Apache POI
Cross-platform (Windows, Linux, etc.)
suitable for both desktop and server applications
high programming effort
Java
EDIT
Here is an older post that has some commonality with your question.
EDIT 2
I see from your comments that you are on Linux and open to either C++ or Java. Definitely use option 2.
JODConverter (Java): the library takes care of spawning OpenOffice in headless mode and talking Uno to it on your behalf. You provide JODConverter with an input and output file name as well as the input and output types (e.g. rtf and pdf), and when it returns to you the output file is ready.
C++: you can fork+exec one (or more, for load balancing) OpenOffice instances in headless mode (soffice will listen for UNO requests on a socket e.g. port 8100.) From your application use Uno/CPP to instruct OpenOffice to perform the conversion the same way JODConverter does (see the JODConverter source code for how to do this.)
/opt/openoffice.org3/program/soffice.bin \
-accept=socket,host=127.0.0.1,port=8100;urp; \
-headless -nocrashreport -nodefault \
-nolockcheck -nologo -norestore
I am successfully using JODConverter from a Java app to convert miscellaneous document types (some documents dynamically generated from templates) to pdf.
Four years late to the party here, but I use Ted in my web application. I generate RTF programmatically, then use the rtf2pdf.sh script included in the package to generate the PDF. I tried OOo and unoconv previously, but Ted proved faster and more reliable in my application.
Use PDFCreator, a free pdf printer. Just print to pdf. You can control this through COM. Example code is in the COM folder of the install directory.
PDFCreator for windows is the easiest for single documents.
It's also possible to automate PDF creation for large sets of documents by converting them to XML and using XSLT and XSL-FO. There are lots of tutorials for this out there.
For a specific language, such as python, libraries exist to output to PDF fairly trivially.
The only advantage of XML over other simpler solutions is extensibility. You could also programmatically output your document in RTF, HTML, TXT, or just about any other text format.
LibreOffice can convert RTF documents to PDF via command line.
Here are the instructions to install it on CentOS.
And this is an example to initiate conversion from PHP code:
<?php shell_exec('libreoffice4.2 --headless --invisible --norestore --convert-to pdf test.rtf'); ?>
PrimoPDF. It acts as a virtual printer, so you just print to it, and out pops a PDF.

I have just installed the free version of BullZip PDF Printer and I want to send .docx documents to this printer without Word installed and it must be free using managed .NET code.
The reason for this is that I have an AngularJS web application and a REST back end that I am developing for a personal project so commercial alternatives are out of the window for cost reasons.
My web application basically generates invoices from a Word .dotx template and I'd like these sent to the BullZip PDF printer where I can monitor the output folder and grab the PDF file before sending it to the browser via REST.
Most examples and suggestions all seem to lean towards using Word installed on the server, or purchasing commercial software and none of these are suitable for me.
There must be some free library in existence these days that can do this without having to buy expensive software for such a simple task.
You can't send a .docx to the Bullzip printer, because it does not accept .docx as a format. It accepts PostScript. In order to get PostScript you open the .docx file in an appropriate application and print it to the printer, the application draws the document content onto the context, and Windows takes care of converting that into PostScript.
The task may seem simple to you, it isn't.
If you don't want to use word then try OpenOffice or LibreOffice instead. Those are the only decent applications I know of which are free and can read .docx files.
My company uses pdflib to generate pdf and now they are thinking of moving to indesign.
I am doing some initial evaluation, this is our normal process:
designer designs the layout of a pdf.
developers put real texts in. Text lengths can vary, so developers will call some function to determine how much spaces it need and if it is over a page, developer will create a new page with some pdflib api.
Can I do the same thing with indesign server?
You can certainly do what you're doing in pdflib and then some with InDesign Server ("IDS"). IDS has minimal "server" features and is mainly a headless version of desktop Adobe InDesign. There are basically two parts to making a PDF from InDesign Server:
Call the server and tell it to make the PDF (this is typically a
SOAP message that tells IDS what script to run and what data source,
possibly passing data and/or job parameters with the SOAP message).
Run a script with ExtendScript (while there are other languages you can automate IDS with, this is far and away the most common).
You can find the scripting documentation for InDesign CS6 and earlier scripts here:
http://www.adobe.com/devnet/indesign/sdk.html
Download the Adobe CS6 Scripting SDK (and possibly the InDesign CS6 Server SDK, though really the Scripting SDK and the IDS documentation installed with IDS is all you need). The Scripting SDK includes the "InDesign Server Scripting Guide" which includes a "Hello World" example that makes a document and exports it to PDF.
The scripting in InDesign CC is available only through the pre-release program: you need to apply to Adobe to get access if this matters to you. CC is actually extremely similar to the CS6 version--the main difference is in added features. A script that works in CS6 is likely to work in CC.
I'm looking for ways to generate pdfs on-the-fly preferably using a command line tool as this will be done from a web-based system.
My requirements include must work on Windows and Linux, should be able to convert Microsoft Word, Excel and HTML into PDF.
Also the ability to concatenate or merge various documents into one PDF output file would be good.
Any suggestions? I would prefer to avoid applications that work as "printer drivers".
many thanks
After doing some research, the best solution I found in the end that could handle all the file formats we needed converting, plus which ran on Linux and Windows was a beautifully elegant lightweight Python script called PyODConverter. This uses OpenOffice (which itself runs in server mode) to do the actual conversions, and it really works beautifully. I used a separate tool called PDFTK to do the PDF concatenation, as I found that ImageMagick loses a lot of information (and creates huge file sizes).
If you find PyODConverter too limited, there is also a more powerful heavyweight option written by the same guy called JODConverter.
Calibre runs on Linux, Windows, and Mac OS X and has command line tools on all three. It can translate a great many document types to PDF and other formats.
(Disclaimer: I'm a heavy user, help out on Calibre's IRC channel, and have been poking at development, so I'm just a bit biased.)
I think this has a command line utility, but not sure. Check this
PDF Creator
Have a look at biopdf, and a PDF printer that uses it called Bullzip PDF. Check the documentation for Bullzip PDF for examples on how it can be automated. It has an API interface as well as the GUI.
Our eTendering solution, www.monaqasat.com, currently works exclusively with PDF documents for various reasons, some of them being security. We are being asked if we can support DWF documents. For this to happen, we would need to find a way to automatically convert DWF documents to PDF, using some kind of Unix application.
Does anybody know any such application, preferably using Rails or Java?
Thanks,

Suggestion would be to install a software printer call its APIs and pass dwf and get back pdf and then apply security as needed.
Autodesk has its DWF Toolkit available at
http://www.autodesk.com/dwftoolkit
It contains full source code in C++ to read & write DWF files, so it should be reasonably easy to make it run under Linux and to use a PDF library to write the output.
We are developing a little application that given a directory with PDF files creates a unique PDF file containing all the PDF files in the directory. This is a simple task using iTextSharp. The problem appears if in the directory exist some files like Word documents, or Excel documents.
My question is, is there a way to convert word, excel documents into PDF programmatically? And even better, is this possible without having the office suite installed on the computer running the application?
Office 2007 allows for this. I have found PDFCreator to be good, the VBA is included in sample files, and have heard that CutePDF is also good. PDFCreator and CutePDF are free.
To work without Office, you would need viewers, as far as I know:

I needed to do this myself, but managed to get it done with .Net and without 3rd party tools:
MSDN: Saving Word 2007 Documents to PDF and XPS Formats
Pretty simple, about 50 lines of code. However I think you will need Word 2007 installed on the machine as well as the ability to Save As PDF
To convert Word documents to PDF, take a look at jWordConvert, a java library that can do exactly that. This will not work with the Excel files though, only with the Word files. The language is not Sharp, it's Java but you could switch to use IText (which is java) instead of ITextSharp.
You can also use a component like activePDF's DocConverter to convert a lot formats to PDF.
Use PDF maker that comes with adobe 7- 9
I just used this code Covert Doc to PDF
I'm surprised Aspose wasn't mentioned here, it's easy, simple, and reliable. Downside is that it is not free.
I've used iTextSharp in the past, it's really good, easy to install (one DLL I believe), the merge takes a bit of tindering so it's not as easy to use as Aspose, but hey, it's free so that is the best part.
TallPDF.NET (comes with a hefty price tag) allows you to serve dynamic PDF from any .NET application including ASP.NET pages and web services.
PDFEdit (free and open source) is an editor for manipulating PDF documents. It has a GUI version and a command-line interface. Scripting is used to a great extent in the editor and almost anything can be scripted. It is possible to create your own scripts or plugins.
The most common way to convert files to a pdf is to print them to a pdf printer driver. There are a number of such drivers, one that i know of that will do the job is Black Ice.
Another is to use Adobe Acrobat's SDK. from memory its very expensive.
Its been a while since i have actually done any work with converting pdf's and the landscape may have changed.
