Hi!
I was surprised that some guys are really using my small tools
pdfseparate and pdfunite. So here a small patch which is hopefully also
useful for them:
patch for psdseparate:
Produce PDF/X conform pdf pages if the originally PDF was PDF/X conform.
I've commited it to trunk for 0.20 release, i have to confess i have not tried
to understand/regtest it.
You see me really contrite: Because of the discussion with Leonard I
suddenly encountered that I forgot to merge an important change: Using
markPageObjects now also with the catalog dict we need of course to
remove the dict entries from catalog which refers to other pages as the
one which should be separated. I forgot to merge this to my new git
copy, therefore it wasn't part of the patch. But unfortunately without
it a lot of PDF can no more be handled with pdfseparate, and a lot of
PDF objects will be kept in the resulting file even if no more referenced.
'Cause You already committed my patch, here just the part which was
missing.
Sorry for the inconvenience,
Thomas
Albert
Cheers,
Thomas
