Depending on what you want to compare, you could have some options... if you wanted to compare the text, you could use some form of text extraction from JPEDAL, PdfBox, or one more I can never think of... and compare the text, or generate checksums from text and compare those (works for me).
if you wanted to compare exact visual representation, you could use JPEDAL or ghostScript to convert the PDFs to images and compare those, or again, generated checksums. -Matt --- Leonard Rosenthol <[EMAIL PROTECTED]> wrote: > At 9:47 PM +0200 7/16/03, Andreas Probst wrote: > >I'm developing an application which creates PDF > files. > > OK. > > > >To automatically test this application, I'd need > to compare PDF > >documents, i.e. compare the current output of the > app to once > >created and verified reference files. > > What would you compare?
