[poppler] poppler pdftops regressions

[William Bader]

Hi Thomas,
I would be interested to see your patch.
The code in my "old" patches has been working well, or at least, I haven't had any complaints since I installed it in August 2011.
I am using -level1sep to make EPS files for CMYK separations.  I am not doing any spot separations from EPS files generated from PDFs.
My software is capable of making spot separations from EPS files, but no one has sent me a PDF with spot color, so I don't have a way to test if pdftops will do what I need.
Regards,
William

        Hi Thomas,

        

        I am working on updating my "old" patches.  I hope to post them
        tonight.

        I am building pages from eps files produced by pdftops, and I
        need -level1sep to get software color separations to come out
        right.

        -level2sep sometimes generates color that the software can't
        separate.

      
    
    Oh, I see. Separation of PostScript is not a quite easy issue. And I
    think, there are some problems in the use of setcustomcolor and
    customcolorimage in the original xpdf code. As far as I remember, a
    collegue of mine gave me some hints in 2007 and I uploaded a patch
    to xpdf to make ps output separable which was never inserted. But
    because PostScript is not my favorite subject, I didn't care. If
    You're interested, I can look if I can find it again, adapt it to
    the actual code and we can work together to get it running. 

    

    Cheers,

    Thomas
