Robert, Sorry for my late response.
This issue clearly is related to the postscript snippets we're embedding in
your patters. This is similar to including an EPS file in your page content. We
can do so for PostScript output only. There should be the possibility to do the
same for PDF (embedding PDF in PDF), but we don't have that for now (and it's
non-trivial).
So there could be the option to convert the PostScript to PDF after it was
created by PyX (for example using ghostscript). Or you embed your pattern data
as (high res) bitmap data ... this should work for PostScript and PDF.
We do not optimize the output for Adobe in any sense. However, you're creating
quite non-trivial PostScript code, which might unsupported by Corel. One could
do some experiments with Corel Draw and whether it can handle a certain
complexity in patterns ... I expect simple PyX output to be processable by
Corel Draw. But in the end we're trying to output PostScript according to the
spec (well, the Adobe spec, as PostScript was developed by Adobe).
Best
