Description joerg.kubitz@gmx.de 2018-03-17 15:04:47 UTC
Description:
.odp files are unnecessary large if they contain a table.

I guess its not needed to store that "previews" at all - because if i delete the preview the file will still work.
The files are a problem if the table has a backgroundimage. Then the "preview" is way too large (Probably the "preview" contains uncompressed image)

Also using the "compres presentation" feature will not delete prevent impress from storing such "previews" and reports estimated file sizes that are totaly wrong.

Steps to Reproduce:
1.Add tables in a impress presentation and storing the presentation as ".odp" 


Actual Results:  
The .odp file contains a zipped "pictures\TablePreview1.svm"

Expected Results:
no SVM files inside odp


Reproducible: Always


User Profile Reset: No

The table background image seems to be a new feature in 4.4, because it does not show when opened in 4.3.

Let's ask what UX thinks about what we should do with the preview.
Comment 4 Regina Henschel 2018-03-18 14:41:51 UTC
The preview is only used in a <draw:image> element as second representation for the <table:table> element. The purpose of a second representation is to allow other applications to present an ersatz to the user, in case this application cannot handle the first representation. But the svm format is not suitable for this purpose, because only LibreOffice and Apache OpenOffice can read it. But both of them do not need it, because they can read the <table:table> element. I think, this "preview" is useless.

Thanks for the assessment, Regina.

Dear joerg.kubitz@gmx.de,

To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information from Help - About LibreOffice.

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
