Hi Ted:
Recently we used PDF Box (http://pdfbox.apache.org/) to convert PDF's to
images within the Java application. But command line works as well.

Hi ted,
Here is a script that shows how using two terminal commands that should be
available via macports. This should give you enough hints to achieve what you
need hopefully :)

I was hoping to find a 'How to' on this. I need to add attachments to my app.
Just adding the pdfs is pretty straight forward. Since they are only uploaded
pdfs, I wanted to process them to some form of tiff to have a thumbnail
available in various sizes and resolutions.
Is there a 'best practice' of this. I started looking at the wonder reference
and I find all kinds of stuff:
ImageMagickCommandlineMetadataParser
ImageMagickImageProcessor
IERImageProcessor
IERThumbnailer
Does anyone have any example code? i feel as though i am just flailing around!
Ted
