I wonder about returned values of this function:
how can it return something else than 2 ?

Is it related to SetMeasurementUnits ?

Hi You Yourself ;-)

I think 99,9 per cent of the pdf-document use "Dots per inch (DPI)".
So it's clear that this functionality is more for very special cases.
You'll get "normally" always the value 2 (for dpi).

Cheers, Ingo

Thank you, so I will consider all returned values different from 2 as error codes.

After looking at the source code it appears that some JPEG images can be specified in dots per centimetre.
