I'm using the "FindImages" command to check, but in a PDF, it's returning the 'out of memory' error. Has anyone ever encountered this problem? Could I use the "HasFontResources" function to check?

We may need a bit more information to help you here.  First, which version of QuickPDF and which programming language are you using?  FindImages returns a zero or an image count, so if it returns, what is the return value? And if it does not return, what is actually showing the 'out of memory' error? Does the problem occur with just a specific PDF, even one with no images, or does it always happen? You could also try the Extraction/ExtractAllImages sample in DebenuQuickPDFLibraryDemo and see if you get the same result there with your PDF.  I hope some of this helps!

Hi Ricardo :) 

If you only wanna check if a pdf is a real pdf or only a converted image you can use HasFontResources.
The function returns with the number of fonts (embedded or only linked).
If it returns with 0 then it's pretty sure that the pdf is only a converted image.

Welcome here :)

Cheers,
Ingo
