Is it possible to create pdf document with variable DPI per page?
I have some 16 pages of scanned document, so all pages are images, for one page it is important to have good quality, minimum 300 DPI, prefer 600 DPI, other pages are fine with 150 DPI.
But I didn't find option to make such document, I can only select DPI for whole document, and if I select 300 DPI file is unnecessary big.
