Apache OpenOffice (AOO) Bugzilla – Issue 12335
Presentation slide names lost when saving in PowerPoint (ppt) format
Last modified: 2019-06-21 18:06:15 UTC
OO ver 1.02, no ver 1.02 in issuezilla dialogs! Open presentation in ppt format, edits ok, save back to ppt format powerpoint page numbers on slide master do *NOT* work in OO, and OO's (inserted as a field) pagenumbers stay fixed at 1 when saved as ppt. Loses text on tabs (becomes slide 1, slide 2 etc.) Show stopper for me as I am editing anothers ppt presentations, and OO formats (which work fine) are not permitted.
Badly worded! I should have said that when a ppt format pres is loaded into OO for the first time, all work fine. If saved as a ppt, both OO and PowerPoint lose the page numbering on the master slide, and the slide names are not visible in OO. Loading back into PowerPoint and resaving gets the slide names back, but not the page numbering. BillK

set to new.
Please write only 1 bug per issue.
The first item is a known bug which is fixed in the OOo1.1Beta. The second part of the bug can't be fixed because PPT have no marker tabs therefore we can't export the names of the slides (the names on the marker tabs.)
I close the issue.
I cannot see the reasoning for this. Does not powerpoint have name attached to a slide, and does not OO have a name attached to a slide? The slide name IS visible if you open a powerpoint, it exports to html OK once opened, but its *LOST* when you save and reopen as ppt. The keyword here is SAVE. So it seems to me OO has a bug in that it is losing information when you save as powerpoint. The fact that you do not have an internal mechanism to handle the information is part of the bug, not a reason to close and dismiss it! BillK
Hi sven Please give a comment to this behaviour. Christian
Your problem with the page numbering field has been fixed. The other problem can't be fixed, because I think there is no possibility in PowerPoint to name a page, instead all slide names are a result of an automatism that takes the content of each title. Thus means the file format of PowerPoint is not designed to store such names, and this is sorry to say, a little information lost if saving from OO to PPT.
If this is the case, why does OO read the titles in correctly if a file is saved from PP, but after being saved fron OO in ppt format, they are lost? If I string the ppt file (saved from PP), there is a section called "Slide Titles" which is not present in the OO saved file, which is smaller in size no editing done). Below is a section cut&pasted from a "vi -b PP_FILE.ppt". The actual titles appear to be before "Slide Title" words. ________________________________________________________
Yes, you are right, the slide names are saved in the "DocumentSummaryInformation" stream of a PPT document, but it does not have any effect if you store names in there, because after loading/saving in PowerPoint, there will always be the slide name generated by the automatism. Try it and change the name in a hex editor, the name is not persistend and will be removed the next time you are editing the file in PowerPoint.
But then what is the mechanism where OO reads the slide names in a PP generated file, but not in an OO one? Agreed that PP is regenerating them, but OO must be reading something in the first place, that is lost when OO saves the file.
It comes, because we try to read the names of the DocumentSummaryStream - So you have convinced me, our export should also store these names. I will reopen this bug, and and implement this enhancement for OOo2.0.

"According to the OpenOffice.org roadmap (http://tools.openoffice.org/releases) this issue was retargeted to OOo Later."

Please have also a look to issue 27581. It's duplicate to this one.
Would someone please change the summary to something like "Presentation slide names lost when saving in PowerPoint (ppt) format"? I had trouble finding this issue because the summary doesn't mention anything about slide names.

This is a PITA when dealing with M$-dependent sites. You open the PPT and they look fine, you save it, re-open and boom! All the slide names are GONE. It's not like PPT97 is a new format, after all... :-)
