My xtopdf toolkit may be of help. It has both end-user tools (some
command-line, some GUI (using wxPython (v 2.6 or higher needed)), and
an API for developers. Both the tools and the API are quite easy to
use.

Check the links here:

This page has a link to an article I wrote for Packt Publishing
(http://www.packtpub.com), on how to use xtopdf to generate PDF from
CSV data - which is the kind you have. You can use the article and the
accompanying code (links available in the article) as a model for your
needs.

This page has links to get xtopdf, a guide to installing and using it
(on Windows), etc.
xtopdf is cross-platform, works on both Linux and Windows. I haven't
yet written a Linux-specific install and use guide, but the generic
instructions in the README should suffice if you know Linux some, how
to install software on it, and how to set up additional Python
libraries on it. You can also post here if you have problems making
xtopdf work on Linux, and I'll try to help. (I developed and tested it
on Linux, then tested it on Windows, so it should work ok on Linux).

xtopdf is written in Python (http://www.python.org, needs v2.2 or
higher) and uses the open source version of the ReportLab toolkit
(http://www.reportlab.org, needs v1.17 or higher, but use the 1.x
series, its not tested with Reportlab v2.x, though it might work with
it).

IMO, Python is easier to learn and develop in than Perl, so if you say
you can do it in Perl, you should be able to do it in Python.

To get the line breaks you can write code to read each cell of each row
of the CSV file, and put the line breaks wherever you want to.

For color changes, its a little more difficult - though the ReportLab
toolkit supports colors, I didn't expose that support in the xtopdf
API, though I may in future. (I did expose the ability to set the font
for any chunk of text, though). If you don't mind digging into the
source, you can try making the changes to allow colors to be specified
for arbitrary chunks of text, as per your need. It shouldn't be too
difficult, since the code is written for understandability, and there
are enough comments.

The CSV and other new formats support (TDV, XLS) is alpha and may have
some bugs. Also, CSV is know to be a variable format - different
products like different spreadsheets, generate various "dialects" of
it. I've not (yet) tested the CSV support with many differing CSV
dialects, only with the MS Excel format of Office 2000.

Feel free to let me know if you find any bugs.

If you make the changes for color support, do consider sending them to
me, to include in the next release of xtopdf. Otherwise, I'll probably
add it myself.
