To put credit where its due, this was Pablo's find.
Indeed very subtle, I didn't notice at all, and PDF viewers also
probably mostly ignore these "/Type"s.

Hi
-Type = pdfconstant(MediaPermissions),
+Type = pdfconstant("MediaPermissions"),
That's an interesting one ... easilly goes unnoticed ... thanks

until it is applied (for full file download, which is available under
the three dots next to the file name).
The created Screen annotation will be given the title, that corresponds
to the second \placerenderingwindow parameter. So here:
\definerenderingwindow[soundplace]
[width=0pt, height=0pt]
\useexternalrendering[mainsound][audio/mp3][sound.mp3][embed=yes]
\placerenderingwindow[soundplace][mainsound]
both the screen annotation and rendition are available under the name
"mainsound". The name "soundplace" can be anything (even "mainsound"),
it doesn't propagate to the PDF file in any way.

The second possibility I proposed previously is not as general, and
implementing it is not worth, until it is really needed (which I presume
won't happen).

Re: [NTG-context] Create an enumeration style
I forgot this : how to reduce the font size for the exponents "er", "e" ?

Hi Wolfgang,
Thanks for the example and the fix, but I would rather think that the « french
» part of ordinals should be
french = function(n)
if n == 1 then
return « er"
else
return « ème"
end
end,
Now if this were not accepted as a fix in core-con.lua, is there a way for a

it is no problem to fix if you all can agree on what/how to fix ...

Hi Wolfgang,
Thanks for the example and the fix, but I would rather think that the « french
» part of ordinals should be
french = function(n)
if n == 1 then
return « er"
else
return « ème"
end
end,
Now if this were not accepted as a fix in core-con.lua, is there a way for a
user to change the default to the above choice in his document ?
