new trickery / acrobat 6

[Hans Hagen]

Hi,

Here are some new thingies for pdf freaks:

   \setupinteraction[state=start]

   \useattachment[whatever][test.tex]

   % \setupattachments[\c!symbool={symbol-normal,symbol-down}]

   \starttext \attachment[whatever] \stoptext

This will embed a file and works ok in acrobat <=6.

If you have acrobat 6, there is now some rudimentary support for pdf-layering.

   http://www.pragma-ade.com/temp/pre-dtp.pdf
   http://www.pragma-ade.com/temp/layers.pdf

In acrobat 6, there is a layers tab on the left end of the screen. The 
pre-dtp file only has layers enabled on the page that talks about layers 
(fyi, this is the presentation i used for eurotex). Not to be redistributed!

... and of course a new beta, take your most complex document, process it 
with \showlayoutcomponents, and you'll get access to all text/graphic 
layers that are in there. Nice for debugging.

Ik heb weliswaar acrobat 6 niet, toch jou presentatie ziet er prachtig uit!

Nice feature to distribute a file together with its documentation, but how
can i extract the attached file. AR (Linux version) seems not to have a
function for this. Is there an utillity program?

However, there is a problem if i uncomment the \setupattachments:

hmm, i've no AR6 to test this and even i don't know what pdf-layering means,
but for me it sound like that we have now two layering methods in ConteXt:
pdf-layering and layers defined by \definelayer... Wouldn't it be better to bring
them together in one user interface and make the pdf-based layering an option:

\definelayer[L1]
\setuplayer[L1][mode=pdf]

or are these both layering methods too different?

In Acrobat (not Reader) it's in File:Properties:Embedded Objects.
(That is, in german it reads: Datei:Dokumenteigenschaften:Eingebettete 
Datenobjekte)
I can't find it in Reader (5.05 on MacOS X).

PDF layers (officially "optional content groups") have not much
to do with ConTeXt layers.

In PDF 1.5 (Acrobat 6) there's a new feature that allows hiding of
some objects, like the layers palette in DTP or CAD software.
But PDF layers are more: they can be connected with special view
sizes (increase detail level while zooming in) and much more.

Think of
- different language versions in the same document
- b/w and color versions in the same document
- additional content that is only visible with a password
- architectural drawings: floors or pipes, wires, walls, furniture ...
   (one layer for each craftsman)
- other CAD stuff
- higher detail level with zoom (I saw this with a city map)
- and much more...

"PDF guru" Stephan Jaeggi said, the possibilities of this new
technique were overwhelming as a Adobe developer showed him
some details.
Think further of layers combined with transparency options --
creative possibilities like in Photoshop! (Don't know if this
really works, but I guess.)

Besides AutoCAD there's no commercial software that can write
such layers -- ConTeXt seems to be ahead the whole industry!
Really big deal, Hans!

Linux AR has this menu entry but it doesn't work.
However, i found pdftosrc by Han The Thanh that seems to be part
of the pdftex distribution. The problem is that one has to know the
number of the pdf-object that contains the data stream.

maybe \setupattachments[symbol=objectnumber] could be implemented?!

Best,
  Jens

I added \PDFattachmentnumber

\definesymbol
   [ObjectNumber]
   [object number \PDFattachmentnumber]

i'll send you a new spec-fdf with its definition in it

this works not exactly how i would expect it:

---
\setupinteraction[state=start]

\useattachment[whatever][test1.txt]

\definesymbol
   [ObjectNumber]
   [object number \PDFattachmentnumber]

\setupattachments[symbol={ObjectNumber}]

\starttext \attachment[whatever] \stoptext
---

gives "object number 7" written in the PDF file, but the
object that contains the _real_ data stream is object 6, not 7:
6 0 obj <<
/Length 20        
>>
stream
Das ist Testdatei 1
endstream
endobj
7 0 obj
<< /Type /Filespec /F (test1.txt) /EF <</F 6 0 R>> >>
endobj

thus, in order to get the correct obj number for pdftosrc one
need the number of the stream-object.

another thing that might be useful is that \PDFattachmentnumber
should read the attachment name as argument and return the obj-number.

the above symbol could then be defined as:
\definesymbol
   [ObjectNumber]
   [object number \PDFattachmentnumber[\currentattachment]]

_and_ one can use it inside the text:

\starttext
This PDF-document has the file test1.txt attached. Users of pdftosrc
can extract the PDF-object \PDFattachmentnumber[whatever] to
get the file.
\stoptext

  Jens

hm, pdftosrc should probably accept both as valid numbers (i.e. in case of 
no 7 resolve it to 6), so if there's someone out there willing to patch ...

this is kind of tricky, since we're never sure if forward or backward 
referencing takes place (apart form the fact that this kind of trickery can 
seldom b eimplemented in a clean way). Anyhow, since i happen to be doing 
things with attachments currently you're lucky; i made you:

\starttext

\definesymbol
   [ObjectNumber]
% [object number {\PDFattachmentnumber[xx]}]
   [object number \PDFattachmentnumber]

\useattachment[test][xx][test.tex]
\setupattachments[symbol=ObjectNumber]
\attachment[test]

\stoptext

(in case of just two args, i.e. no [xx], you need to feed the filename, 
i.e. test.txt)

I'll send you the patched spec file (keep in mind that this 
\PDFattachmentnumber is some driver functionality, and not something of teh 
core).
