It should work when you use “width=\the\dimexpr\textwidth/2\relax” or
“width=\the\dimexpr0.5\textwidth\relax”.

Re: [NTG-context] 3D annotations
Dear Hans,
I wrote to you
thank you for your latest effort to put u3d support in a working state, but
more thanks for more effort, but
May be a more robust way is to read first 3 bytes of the model file, since
U3D or PRC signature is always there - that can be done instead of
relying on file name extension or only in case it it not u3d or prc.
you have implemented reading the file signature, but it is now
almost useless, since if a file has extension other but U3D or PRC
3D annotation code will not be called by file inclusion mechanism
and io.readdata routine is called
local subtype, subdata = U3D, io.readdata(foundname) or
- what's that?
One more point - preview bitmap images in 3D annotations are now disabled
since necessary functionality of measuring XForms is missing -
please, consider the following workaround.

Also PRC annotations have to trigger setting PDF version to 1.7.3

It can be done per your advice directly
\doPDFaddtocatalog {
/Extensions
/ADBE
/BaseVersion /1.7
/ExtensionLevel 3
}
But what about an interface like \pdfmicroversion and
automatic pushing up of PDF version once PRC annontation happens?
i don't know that command and anyway want to get rid of all commands
that start with \pdf
concerning versions ... peter rolf and i are working on detailed support
for standards (also related to preflighting) and before i even want to
look in some automated version handling we first need to get that bit
done well
Also I try to remind you about pdfboolean problem in lpdf-ini.lua

local function pdfboolean(b,default)

else

end
end
i need to check it ... later (also for interferences)
PS. And a great palliative way to deal with 3D annotations is via

well, one can attach files as-is already (unless it's broken)
I can not deduce from existing sea of ConTeXt code the status of file
attachments support.
\attachment has been there for ages
actually, all kind of annotations hav ebeen supported as soon as they
showed up in acrobat (mediademo is an exmaple of flash) but i gave up on
implementing these things too early as in acrobat/pdf such new tricks
normally needs a few versions to reach stability

[NTG-context] 3D annotations - was: status of node.write
Dear Hans,
On Wed, 24 Mar 2010, Hans Hagen wrote:
there is u3d support presen tbut nobody tested it
thank you for your latest effort to put u3d support in a working state,
but as of now even the most basic test from back-u3d.mkiv does not work
and is not supposed to:
grph-u3d.lua needs adding to the preamble
local pdfannotation = nodes.pdfannotation
local todimen = string.todimen
and replacing
node.write(annotation... with node.write(pdfannotation(annotation...
to at least make code run without throwing error messages.
lpdf-u3d.lua has more severe problem:
-- weird, has to be a /Form and not an /Image so we need a wrap = true
key
-- local figure = img.immediatewrite { filename = preview, width =
width, height = height }
local figure = img.immediatewrite { stream = .5 .75 .75 rg 0 0 20 10 re
f, bbox = {0,0,20,10 } }
shows that option to include a bitmap preview image into 3d
annotation is just commented out.
On the other hand, an approach like in LaTeX package attachfile2 may be
convenient - a PDF with just 3D annotation and minimal support elements
(with or without preview) is attached to the main document, that has a
clickable image that activates that attached PDF document in a separate
window.
In this case the preparation of the attaced PDF can be
completely delegated to external utility.
Does attachfile2 analog work in ConTeXt now?
Where to look for usage examples?
Sincerely, Michail
