attachment attaches twice

attachment attaches twice

[Reviczky, Adam]

[-- Attachment #1: Type: text/plain, Size: 1034 bytes --]

Hi

I'm trying to use PDF attachments again, but run into some issues.
Here's my small example (att.tex):
%%% start %%%
\setupinteraction[state=start]

\starttext
\useattachment[myfile][title][name][att.tex]
\attachment[myfile]
\stoptext
%%% end %%%

1) Using context-current makes 1 attachment, whereas context beta makes 2 attachments (page + attachments tab?).
I've attached the two generated PDFs. I guess the "attachments tab" attachment is not intended.

2) The third parameter should give a custom name for the attachment, and I recall this from old times (maybe mkii) to behave like that, though I can't reproduce this now. Is this broken (as it has no effect right now)?

3) I want to have some attachments (source code) from a url, can this be added to behave like \externalfigure?
I want to use it like this: "\useattachment[myfile][title][name][http://git.example.com/master/att.tex]"
Right now that just attaches an "Unknown" (maybe shortcut) but it cannot be viewed/opened or saved.

Thanks
Adam

Re: attachment attaches twice

[Michail Vidiassov]

Dear All,

to be precise, the attachment is attached once
(can be seen if one inspects the sample PDF files in uncompressed form with 
any text or binary editor - if you do not have Adobe Acrobat), but is 
listed twice by Adobe Reader.

       Sincerely, Michail

PDF spec states
----------
An embedded file stream shall be included in a PDF document in one of the 
following ways:
•	Any file specification dictionary in the document may have an EF 
entry that specifies an embedded file stream. The stream data shall still 
be associated with a location in the file system. In particular, this 
method shall be used for file attachment annotations (see 12.5.6.15, "File 
Attachment Annotations"), which associate the embedded file with a location 
on a page in the document.
•	Embedded file streams may be associated with the document as a 
whole through the EmbeddedFiles entry (PDF 1.4) in the PDF document’s name 
dictionary (see 7.7.4, "Name Dictionary"). The associated name tree shall 
map name strings to file specifications that refer to embedded file streams 
through their EF entries.
----------

while code in lpdf-wid.lua sends everything to EmbeddedFiles - including 
files associated "with a location on a page in the document" as in the 
examples in the originator's post.

For example http://www.microtype.com/showcase/EmbedFiles.pdf
has it done correctly, EmbeddedFiles refers only to that embedded files 
that are not linked to particular icons on pages.

          Sincerely, Michail

PS. did not experiment with patching lpdf-wid.lua myself yet...

i'll patch lpdf-wid but somehow I get the impression that it's more a 
viewer issue (the list shown seems to be a merge of filename as well as 
symbolic names while a clever list builder should look at the referred 
objects) ... but maybe no one else usesvdifferent symbolic names (we had 
similar issues with fields in the past and even now advanced field 
support is somewhat bugged one or the other way, depending on the viewer 
version, esp chained ones)

it'd be nice to not only fix icon-linked attachments (current 
functionality), but to also allow to create document-level attachments
not linked to icons - not that I see any particular use for that just now,
but since functionality is already there (but misused) it'd be a pity to 
just drop it.

Re: \useattachment: Embedding files in PDFs - was "attachment attaches twice - more research"

[Michail Vidiassov]

[-- Attachment #1: Type: TEXT/PLAIN, Size: 1707 bytes --]

Dear Hans,

I'd like to remind you about an old problem report
------
From: Tobias Burnus
Date: 2008-01-04 16:01 +300

I can use \useattachment to embed/attach files in a PDF file. I can use:

\useattachment[whatever][title][newname][test.tex]
\attachment[whatever]

This creates an attachment with the description "title" and the name
"test.tex". However, how can I set the author/subject? (Shown in tool
tip of the annotation symbol; it is shown above the description;
actually subject is enough for me.)

Additionally, I miss the file size and possibly the modification date
for the attachments; they are often handy to have.

Is is possible to associate an embedded file stream with the document
itself without creating an annotation symbol as with \attachment in
ConTeXt? (The PDF spec allows this; cf. e.g. 3.10.3 in the PDF spec and
http://www.microtype.com/showcase/EmbedFiles.pdf for an example PDF file.)

-------

what he names "author/subject" is the "T" entry in annotation dictionary 
(the same where /Subtype /FileAttachment goes), that is described as
"The text label that shall be displayed in the title bar of the 
annotation’s pop-up window when open and active. This entry shall identify the user who 
added the annotation."
It appears as the upper of the two lines that are shown when the mouse 
pointer is over file attachment annotation icon (the lower one is the 
description mentioned above).

And for "file size and modification date" to show up file stream has to 
look like
8 0 obj<< /Params << /ModDate (20050217) /Size 2048>> /Length 1218>>stream
not just
15 0 obj<< /Length 144>>stream
as it is now.

        Sincerely, Michail

to say the truth I do not understand what are you talking about :(
The issues I have in mind - separating global attachments and attachments 
linked to icons on pages, additional descriptions for attached files -
are addressed in the attached patches.
I am not sure about using attachment lebel as "T" key, that is indended for 
following:
The text label that shall be displayed in the title bar of the annotation’s 
pop-up window when open and active. This entry shall identify the user who 
added the annotation.
and shows as the upper line when mouse pointer is above attachment icon.
Did not try to have file size and time information added to file stream -
but it'd be nice to have.

         Sincerely, Michail
PS. Patches show what I want done, not how it is to be done.
Just hope that my lua may be more clear than my English.

Attachments have some history in pdf and each version was slightly 
different. The same is true for widgets. Some of that has to do with 
security issues, some with the fact that acrobat editing interfaces 
always lag behind new features, etc. I gave up on advanced stuff when I 
noticed that custom visualizations had changed again. I'll have look at 
it but not this week (away for a few days). I also need to it with Luigi 
as he often has torture tests laying around. We also need to keep the 
a/x standards in mind.

as far as I understand ConTeXt now can not link file attachment to 
arbitrary picture, just to some predefined icons. Am I right?
Is it going  to change? Soon? There are comments in the code about
lack of measurement support for XForm - is that the issue and what
that issue is?
I have already met that complaints in 3D Annotations support code.
BTW, I am interested in FileAttachment  Annotations as a way to
work with 3D models. With LaTeX the main PDF file may contain a 2D picture,
that can be displayed in any PDF viewer, but if you click on it in Adobe 
viewer attached PDF file opens with 3D model in it. That attached file may 
be produced by some third-party tool, since often such tools output not 
just 3D model fit for including in PDF, but a one-page PDF with the 3D 
model, complex JavaScript to control it (for example to animate it) and 
some intarctive text related to the model.

I'm not sure what you mean here. There is some u3d and shockwave 
support. (I added u3d because someone asked it but the requester never 
tested it). Anyhow, these features are only extended when we (luigi and 
me) get proper public test files

Concerning attachments, the next beta will have a new definition model 
with inheritance but the \use.. method is still there as well.

The hidden method will not place an annotation. Definition is not really 
needed, so a direct \attachment works ok, but a bit of abstraction 
(separation between definition and use) does not hurt

% old but stil valid method (consistent with other \use):
%
% \useattachment[test.tex]
% \useattachment[whatever][test.tex]
% \useattachment[whatever][newname][test.tex]
% \useattachment[whatever][title][newname][test.tex]

on one hand your patch fixes the bug that is in the Subj. of the 
thread, but it does just that and nothing more. It is a pity
to see the opportunity to enhance attachments support wasted.
It'd likely be a long time before you revisit the issue :(

this is a bit of a weird comment given that i haven't uploaded anything 
that you can comment on; as far as i can see there were a couple of 
issues: attachments without associated annotation, and labeling and both 
are covered, but using the same command and extra keys/values ...

sorry for being so dumb,
but on one hand you "haven't uploaded anything",
on the other "there were a couple of issues" that "are covered" by now,
and on the third one first-setup.sh brought me this morning lpdf-wid.lua
that now has 
---
local ignorereferenced = true -- fuzzy pdf spec .. twice in attachment list, can become an option
---
etc. - that change caused my comment.

On the positive side - ConTeXt internals are your internal affairs,
you are more sovereign than some kings and revolution leaders ;)
Just tell us what that user-level "extra keys/values" are and we'll sing, 
dance and rejoice, being innocent of knowing what only the ConTeXt creator is to know.

       Sincerely, Michail

Dear Hans,

when you fixed the bug with attachment being listed twice
in the attachment list, you also enhanced attachment support

as far as I understand, "attachments without associated annotation" are
called "hidden" in ConTeXt, as in

\attachment[test][file=att.tex,title=Oeps,author=Hans,subtitle=TeX File,method=hidden]

But that does not work and, as far as I can see from the current beta code, 
is not supposed to. For example, in lpdf-wid.lua we have

local function flushembeddedfiles()
     if next(filestreams) then
         local e = pdfarray()
         for tag, reference in next, filestreams do
             if not reference then
                 report_attachment("unreferenced file: tag '%s'",tag)
             elseif referenced[name] == "hidden" then
                 e[#e+1] = pdfstring(tag)
                 e[#e+1] = reference -- already a reference
             else
                 -- messy spec ... when annot not in named else twice in menu list acrobat
             end
         end

lpdf.addtonames("EmbeddedFiles",pdfreference(pdfflushobject(pdfdictionary{ Names = e })))
     end
end

Note the "referenced[name]" part, while there is no "name" variable.

It seems the working code did not find its way into released version
and some draft got shipped.

           Sincerely, Michail

Thanks, but the question is still why the beta produces this while it is fine with the current.
