I don’t think it’s possible. The PDF specification is too wide open. I have seen many PDF’s that appear the same yet are constructed so differently that the only valid consideration is visual appearance & field input performance. A comparison of the PDF file contents is almost certainly going to vary from one producer to another.

I'm willing to migrate from QuickPDF to CutePDF.

Then, I want to compare the PDFs generated from both ones.

Say that I have generated a PDF , from a template, mixing my data, using QuickPDF. Then I generate PDF_ONE.

Then I do the same, by using CutePDF, generating PDF_TWO.

Now I want to compare PDF_ONE x PDF_TWO, in order to see if they're identical.

What could I do ?

I expect form fields to be flattened on both PDFs....

My intention is to detect, automatically, if there's some problem on any one of them...

Thanks !
