Hi DanielMap
There is no dialog to change the setting of the PDF files, but some variables that change the resulution and compression. Try the following script and compare file size and quality of the files.
'Default settings
PDFJPGCompressed= "No"
PDFResolution= "default"
Call PicPdfExport( "c:\file1.pdf")
PDFJPGCompressed= "high"
Call PicPdfExport( "c:\file2.pdf")
PDFResolution= "72 DPI"
Call PicPdfExport( "c:\file3.pdf")
Hope this helps.

Hi DanielMab,
If the green variables winner posted aren't available yet in your DIAdem (they're pretty recent), you can still change the dpi resolution manually by going to the Windows Start menu, selecting "Settings", "Printers and Faxes", then right-click on the "DIAdem PDF Export" printer and select "Properties", then choose the "Advanced" tab and choose a smaller Resolution (72 dpi is the minimum).
On my current laptop with DIAdem 11, I can no longer find the resolution setting in the properties dialog, but on my old laptop with DIAdem 10.1, I can find and change the above-described resolution setting, and the next time I print PDF files from DIAdem 10.1, I get smaller (and grainier) PDF files. It looks like the new PDF printer driver that DIAdem installs takes its resolution setting from the programmatic call and can not accept a manually selected, static resolution setting like the older PDF printer driver could.
