I found the Coldfusion .pdf writer to be too slow for my use, and I
wrote a simple .pdf writer component that accepts a comma separated list
of .tiff files and writes out a .pdf file. I have been using it
successfully now for about 4 months, writing on average 1000 .pdf's a
night composed of between 2 and 20 pages each. Here is the component if
it will help you! It uses the iText java .pdf library
(http://www.lowagie.com/iText/) The component will handle multi-page
tiff's as well.
<cffunction name="writePdfFromTiffs" output="false"
returntype="string" hint="This will output a .pdf file containing
multiple tiff images">
<cfargument name="pdfOutput" required="true" type="string"
hint="Provide a full path to output your PDF too">
<cfargument name="tiffList" required="true" type="string"
hint="Provide a comma seperated list of tiff images to include">

Russ, how do you do it and how many and what size documents do you
typically have? How long does it take to convert say 10 documents to
one pdf?
Thanks, Peter
