PDF inclusion warning

Post by JefVL »

Hi all,

I am finishing up my thesis in LaTeX, but suddenly I received a warning that I never saw before on other computers (it's been a while since I've used this one, but last time it wasn't showing yet).

The warning says the following:
pdfTex warning: pdflatex.exe (file: <my file>): PDF inclusion: multiple pdfs with page group included in a single page
I already googled a bit and found that it has something to do with PDF files having a feature called "Page groups", files created in Adobe having a /group entry in their code, and these to combined give the warning because LaTeX has issues with including multiple page groups on one page. I find it a bit strange since it only concerns 1 picture, and not multiple.

I've also tried some solutions that other people posted on the internet. These included saving the PDF file to be compatible with Acrobat 4 (pdf 1.3), and converting the file to a ps file (PostScript) and back to pdf. This last option however is something I'm not entirely sure about if it worked or not because I used an online converter to do the job and I don't know if it's trustworthy. The other info I found suggested to use Ghostscript to convert the pdf to ps, but after downloading that program I can't get it to work since I don't know how to use it, and am unable to find any tutorials on how to do what I need done, resulting in me feeling dumb since I'm one of the best with computer thingies among my friends.

If anyone knows what to do, or if anyone can give me a detailed step-by-step explanation on how to do the conversion in Ghostscript, I'd be very grateful...

Thanks in advance!
Jef

A real solution is still welcome if anyone has one, but I found a workaround that gets rid of the warning: open the pdf in a standard pdf reader, take a screenshot and save that as picture. Since it loses some resolution, it's not optimal, but I can't stand seeing errors, warnings or bad boxes and I don't see any significant loss of quality, so I'll go with this for now.
