RE: [libreoffice-users] Rountrip Conversion Problems (was Re: Should LibreOffice ... secret formats?)

It is tough to figure out what bug to report in the multi-column text-flow problem.

In the dashed line problem, it is easy to report two bugs, one for dashed lines to .doc and one for 
dashed lines from .doc.  

In this multi-column flow case, LibreOffice can round trip, and the bug is in the change to column 
and spacing widths that have the material not fit and not flow properly.

So there is a bug around not being able to consume what it produces properly.

THE SERIOUS INTEROP QUESTION

The other problem, that I don't know how to deal with, is whether that is a proper .doc for what is 
in the .odt at all.  I *think* the problem you are seeing is that the frame on one of the images in 
column 2 is actually too wide.  Or maybe column 1, and it forced the kind of adjustment you are 
seeing.  But the consequences in Word are particularly awful.

What is even more amazing is that what Word does with that specific .doc has not changed since 
Office 97!!  NoOp gets near-identical results from the .doc in Word 97 that I get from it in Word 
2010.  I bet if the second page is examined, the column 2 content will be seen to have flown down 
to the second column there.  (The only difference that I see in Word 2010 compared with the Word 97 
screen shot is that 2010 has a double title over the graph in column 3 and consequently more text 
flows to the top of column 4.  I hadn't noticed that additional title doubling in my earlier 
report.)

On the other hand, what Word 2010 does with the original ODT is strangely close to what it does 
with the .DOC, and that is *really* inexplicable.

So there's not enough here for an isolated bug.

MORE DETAIL: I forgot to check this before.  When the .doc is opened in Word 2010, the columns are 
set as four across, with column 1 1.6", 2-3 at 1.25" apiece, and column 4 at 1.6".  The spacing is 
0.7".  The equal column width box is not checked.  The margins are 0.35" top, left, right, and 
bottom, with no gutter.  The page is US Letter.

If I check "equal column width" I get 1.43" columns all the way across and 0.7" spacing. The 
duplicated titles I mention disappear, but there are other duplications in the columns.

(sigh)

FURTHER ANALYSIS POSSIBILITIES

Although it introduces more variables that can't be controlled, I think there are three avenues of 
further exploration:

 1. Make a .doc that seems as correct as is possible.  See what LibreOffice does with that.  Then 
make an .odt from that .doc from Office 2010 to see how that round-tripping works.  This might 
localize *something*.

 2. Do the same thing with .docx in both directions.  If experience is any guide, this will be 
worse, but because .docx is an XML format it might be possible to find more clues by inspecting the 
XML that travels in various directions.

 3. Make a Microsoft Word XML file too.  This is a rarely-used variation that *might* provide more 
clues.  There are filters for reading those into LibreOffice also, although I have no clue 
concerning their quality.  (This can be round-tripped out of LibreOffice too, I believe.)

There is a project, Apache Poi, that has Java tools for manipulating and converting Microsoft 
Office format documents.  That might help to examine the .doc files to see where the discrepancies 
arise.  That's a lot of work to invest for this particular file.  I think starting with variations 
of simple cases may work better.

Hi, Dennis:


       Thanks very much.  Should I do something to file bug reports on 
these items?
