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"
overwrite="yes"
destination="#outputdir#" scale=100 format="jpg"
resolution="high" imageprefix="#filename#" >
The resulting images are identical in size. I checked the actual
resolution in Fireworks and it's 72 for both images.
I'm using CF8 - maybe this has be fixed in 9?

Stefan
