[OS X TeX] Re: pdf v1.6 problem

[Chris Milne]

Ross, William,

Thanks for the replies. After a little investigation into pdftex it
appears that pdftex.cfg no longer exists & has been replaced with
pdftexconfig.tex. The option William is referring to has been changed
to \pdfminorversion (though in my copy of pdftexconfig.tex it was
still \pdfoptionpdfminorversion).

Adding \pdfminorversion=6 to the preamble of my document makes the
original error message go away, but it's now replaced with:

<figures/cascades-CS2-111212-labelled.pdf, id=854, 564.09966pt x
526.2119pt> <use figures/cascades-CS2-111212-labelled.pdf>
figures/cascades-CS2-121121-labelled.pdf
Error: PDF version 1.6 -- xpdf supports version 1.5 (continuing anyway)

So it appears xpdf is getting involved somehow & it can only handle up
to PDF 1.5. Which presumably means I'm dead in the water.

I've fiddled with the PDF Optimizer options in Acrobat & whatever it's
done to combine the two figures in v7.x is FLAKY & it can't seem to
decide how to fix the problem so it's backwards compatible. I have yet
to find a combo that works & so I give up.

I've wasted too much time on this already & frankly it's not that big
a deal, thanks for help everyone.

Chris

Note that editing pdftexconfig.tex appeared to accomplish absolutely
nothing. No matter what change I made to it, when I compiled the LaTeX
doc up it got ignored. I had to put \pdfminorversion=6 into the
preamble for it work.

I believe you need to add

\pdfoptionpdfminorversion=5

(or maybe 6 or 7?) to your document preamble. Check the pdftex
manual, but if memory serves, that's the option for controlling
supported version.

To up the version number for all jobs, include a line

pdf_minorversion 6

within the  pdftex.cfg  file.
To find this file, use in a terminal:

  kpsewhich -progname=pdftex pdftex.cfg

No, that's not quite correct.
This parameter controls the *warning message* that is produced.

That is, if you set the number higher than what the pdfTeX binary
**actually** supports, then pdfTeX now says something like:


 Version 1.6 is a higher PDF version than is supported (1.5).
 Trying anyway.


So maybe it'll work, maybe not.
Presumably this depends on whether any 1.6 specific stuff
is actually used in the imported image.
In practice I've not had any trouble (that I'm aware of)
importing images that purport to be 1.6.



Hope this helps,

      Ross
