PDFs should conform the specification, but they are quite complex and
as therion constructs them using low-level PDF commands and there is a
custom EPS to PDF conversion, there is a possibility for some errors.

Therion output is usually tested in Adobe Reader, which is quite
sensitive to problematic PDF files. I tried to convert some complex
maps to JPG format using GS 8.71 and did not get any warnings. Could
you post some problematic file?

[Therion] Generated PDF compliant to spec

PDFs generated by me from Therion 5.3.8 are reported by Acrobat as being 
pdf version 1.5, that is compatible with Acrobat 6 and above.

I'm afraid I don't know Ghostscript, but Acrobat will export as jpg.

I tried converting my PDF map to a JPG using Ghostscript yesterday.  It seemed 
to convert properly, though I saw a handful of warnings that there was an 
"Unknown operator: 'pop'" in the source PDF.  Is Therion producing something 
which isn't to spec, or producing a newer version PDF that Ghostscript isn't 
prepared for?  I was using Therion 5.3

Thanks,

Carl
