Yep, and you *should* have the option to set a compression percentage for that,
so I would raise that bit as a bug.
I'm guessing the resolution setting is
Hi all,
I am now successfully converting PDF files to JPG. I'm wondering what

Yeah good point - I will test with some more obvious material and post

This could be a bug. Here's what I run:
cfpdf action=thumbnail source=#uploaddir#\#filename#.pdf
overwrite=yes
destination=#outputdir# scale=100 format=jpg
resolution=low imageprefix=low_#filename#
cfpdf action=thumbnail source=#uploaddir#\#filename#.pdf
I don't know, download CF9 and see. My guess is, probably not.

The resolution of an image defines the default physical size it gets sent to
the printer as (and it can generally be overridden at print stage anyway).
So you can probably ignore it.

resulting images are identical in size. I checked the actual
resolution in Fireworks and it's 72 for both images.
It may well be that Fireworks is ignoring the value provided - you'll need to
use a metadata viewer to find out what value the actual file has, rather than a
graphics editor.

AFAIK, it is related to jpedal (used internally to extract the images). You
should find some CF specific references in google. Search on:

I'm not interested in printing though. I'm converting PDFs to image

processing instead, which is fine, I just wanted to make sure I
