Summary: Synchronization: pdfsync.sty embedded (1) 
Resolution: Accepted
Group: v1.50.0
Category: User interaction

Initial Comment:
To the administrator, please remove the preceding patch submission

The purpose is to implement some extensions very useful for 
synchronization, both forwards and backwards. Synchronization is the 
ability for a text editor and a pdf viewer to work together, displaying the 
same thing at the same time. For example, a text editor can ask a pdf 
viewer to display and outline the character in the output corresponding to 
the character under the cursor.
Attached is a zip file containing diff against version 1.40.4, explanations 
and demonstrations in
synchronize.readme/synchronize+frames.pdf

PS: I have problems with my connection

The pdfsync package is a tremendous boost in the
productivity for everyone that learns about it, specially
when working with pdf files of more than a couple of pages.
The synchronization between pdf viewer and tex editor is
essential for keeping track of the changes you are doing
without having to search over lots of .tex files or having
to scroll over the entire pdf to find the relevant section.
My work on latex is mainly done on Mac OS X using
eclipse+texlipse+pdftex and the Skim PDF reader and with my
discovery of pdfsync, the whole experience of writting latex
documents have improved to the point i would not use
anything else. So i would love to have this feature included
as soon as possible so it can become a standard and avoid
any package incompatibilities.

Also, it is well known that the syncrhonization feature has
been present a very long time for latex output to .dvi files
and i think it is the time to bring this essential feature
to the pdftex world to achieve the same level of functionality.

I understand the issue correctly, Laurens' suggested modification of pdftex 
would make synchronization a (potential) standard in all TeX installations 
and formats, without package incompatibilities. This should be regarded as 
an improvement over present implementations of this essential feature, at 
least essential for those who, like Schremmer, spend hours each day going 
back and forth between TeX source and pdf output.

Please add it soon,

As someone who spends hours everyday going back and forth between source 
and pdf with TeXShop under OSX 10.4.11, any improvement in the 
synchronization would be invaluable and so would Laurens's improvement.

Ok, I found some time to make the necessary corrections and improvements.

The attached file contains explanations and examples about synchronization. 
The patch.diff file is the result of the "svn diff" command against the latest 
trunk (as of 01/24/08)
Compared to the previous versions, the command line switch now works 
properly and there is now a mean to take into account the x and y offset that 
may be used by a postprocessor like dvipdf.

Well, it is very difficult to find any kind of information/help about pdftex 
development, so please don't be too crude with me.

Also, the command line switch seems to be broken. It only
works with \synchronize=1 in the source here.

Please update the patch against trunk and please use svn
diff. I refuse to look at this patch more closely since the
diff includes all the .svn files.

Synchronize3.zip is available.
It just adds a flag in the .sync file to indicate whether dvi or pdf mode was used.
So far I have found only one problem, using dvips or dvipdf with a concrete 
offset (-x and -y options) will break the synchronization. If such a filter is gentle 
enough to indicate that it used a custom offset, then viewers can take this into 
account and the synchronization is not broken. Viewers will check the above 
mentionned flag to look for customized offset.

Synchronize 2.zip is a version extending the previous one. Now synchronization 
works the same for both dvi and pdf output modes.
