Ghostscript PDF generates warning on open

[baltman]

I'm generating PDF files with GS and when trying to open the results I get a long warging to the effect that "This file appears to use a new format that this version of Acrobat does not support..." I'm using Reader 6, so I doubt this is the case.

After pressing "OK" the file opens and looks just fine.

I can toggle the compatibility parameter to 1 from 2/3 and everything works fine, but the resulting PDF is 7x larger.

Is there another setting I can play around with to get compatibility AND a smaller file size?

This line makes a smaller file with compatibility issues:

 -q -dSAFER -dNOPAUSE -dBATCH -sDEVICE#pdfwrite -sOutputFile#]+m_outfile +[ -dnodisplay -dCompatibilityLevel#3 -c .setpdfwrite -f ] +m_ifilename

And this line makes a larger file WITHOUT compatibility issues:

 -q -dSAFER -dNOPAUSE -dBATCH -sDEVICE#pdfwrite -sOutputFile#]+m_outfile +[ -dnodisplay -dCompatibilityLevel#1 -c .setpdfwrite -f ] +m_ifilename

Thanks,
Brian

Can you post a link to the file?

Applications are allowed to put their own objects into a PDF file, which are supposed to be ignored by PDF consumers.

But I would be surprised if GhostScript does that.

What is your source document? PostScript? Who produces the PostScript? There could be, for example, a pdfmark dictionary which GhostScript turns into a COS object that Reader doesn't recognize.

The source is an HTML file I generate from scratch with no special characteristics.

I've automated an open with IE 6, print to file using the Lexmark Optra Color 1200 PS print driver.

Then I run a modified version of a FoxPro program that automates GS (code available in faq184-2143) which among other things runs GS with the parameters line I posted above.

Strange. I have no obvious answers for you.

I'd like to see the PostScript generated by IE, just for grins.

I can create a dummy report and e-mail the PS and PDF files to your info address if that's OK with you.

Thanks,

That would be fine.

I think I've resolved my issue, which mostly has to do with my integer based thinking. If I set dCompatibilityLevel to 1.2, then I get a small file without the warning.

Thank you for your time.
