Description Christophe Strobbe 2011-12-06 04:14:48 UTC
When exporting ODP from Impress to the Microsoft PowerPoint format PPT, both the title and the description (text alternatives for accessibility) on images is lost.

Steps to reproduced the issue:
1. Create a new presentation in Impress.
2. Add an image and give it only a title (right-click, choose "Description" from the context menu and fill in "Title").
3. Add an image and give it only a description (right-click, choose "Description" and fill in "Description").
4. Add an image and give it both a title and a description (right-click, choose "Description" and fill in both fields in the dialog window).
5. Save the file as "Microsoft PowerPoint 97/2000/XP/2003 (.ppt)".
6. Open the PPT file in Microsoft PowerPoint, right-click on each image, choose "Format picture", then "Alt text": both the Title field and the Description field are empty.

Note: you can give images a name (so they become visible in the Navigator), but this does not make a difference.

Desired behaviour:
When exporting to PPT, ODF's title and description should be mapped to
PowerPoint's title and description.

For a test file, see the one attached to bug 43547.

Version info was previously LibO 3.4.3. I confirm that this bug is still
present in LibreOffice 3.5.0 RC1. Changing status from UNCONFIRMED to NEW.

I assume that once bug 43547 is fixed, it will automatically fix this issue.

Comment 7 Christophe Strobbe 2018-10-22 14:39:59 UTC
I retested this in LibreOffice Impress on Manjaro Linux; the issue is still present when exporting to PPTX (but now when exporting to the older PPT format). Both Title and Description are empty after exporting to PPTX ("PowerPoint 2007-2019").

The only difference in the process is that you need to select 'Description' from the Format menu in order to access the Title and Description, instead of using the context menu.
Comment 8 Christophe Strobbe 2018-10-22 14:51:36 UTC
My previous comment should just have said that the issue no longer exists for the PPT format (at least when I reopen the PPT in LibreOffice Impress). PPTX output is covered in a different bug: https://bugs.documentfoundation.org/show_bug.cgi?id=43547.

I think you have it backwards. Name/Description (but not title) are retained for PPTX, but all are lost with PPT.

tested with LO 7.0

PPT is tested with MSO and bug is still here.
Comment 12 Stéphane Guillou (stragu) 2021-07-12 13:16:07 UTC
Reproduced in LO 7.3 alpha0.
You don't need MS Office to test this:

1. Open Impress
2. Insert an image
3. Fill in the "Title" and "Description" fields for the image
4. Save as > PPT
5. Close and reopen

Observed: both fields are empty.
