Adding picture files into a diadem report makes large pdfs

[pelleK]

When I add a 2,5MB picture file into a Diadem report and export it as pdf, the file size of the pdf gets almost 26MB. Why is that?

Thanks,

Pellep

Hi Pellep,

That does sound like a disproportionate size jump.  Possibly the difference is in the picture quality used to store the PDF file.  If you use a very high PDF pictiure resolution to store a lower resolution picture, the resulting PDF file will certainly be larger by some factor.  If you are using DIAdem 11.0 or later, you can programmatically set the PDF resolution-- here are the possible settings:

PDFResolution = "Default"

PDFResolution = "72 DPI"

PDFResolution = "150 DPI"

PDFResolution = "300 DPI"

PDFResolution = "600 DPI"

PDFResolution = "1200 DPI"

PDFResolution = "2400 DPI" 

If you're using a version of DIAdem prior to 11.0, you can still affect this setting in the printer setup of the "DIAdem PDF Printer" in "Start Menu >> Settings >> Printers and Faxes"
