Repro OO 3.3 and 6.4 alpha1. New. Somewhat related bug 112721 in See Also.
The focus of test.ppt from comment 1 is on the second paragraph(456), which actually starts at linespacing multiple: 280% according to PowePoint 2003 and PowerPoint 2016.
It looks like the code very deliberately messes this up - based on font scaling. There is no value in FontIndependentLineSpacing (not sure how this is different from pPara->mbFixedLineSpacing, where elsewhere FontIndependLineSpace >>= bFixedLineSpacing) and therefore everything scales by pDesc->Scaling + 0.5. Unfortunately, all this code comes from OOo, so it is hard to identify the purpose of it. The code is at least related to this OOo bug - https://bz.apache.org/ooo/show_bug.cgi?id=28747 Since everything imports the same as MS Powerpoint, this must be an export bug. On the other hand, since this adjusts the LO value on export, it ought to do the reverse equation during input. So the first task is to find out why this scaling code was added in the first place. And with that I walk away since I don't understand font / scaling / presentation stuff.
Dear xiaohaodaye, 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. If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice. Please DO NOT Update the version field Reply via email (please reply directly on the bug tracker) Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not appropriate in this case) If you want to do more to help you can test to see if your issue is a REGRESSION. To do so: 1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from https://downloadarchive.documentfoundation.org/libreoffice/old/ 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'; 4b. If the bug was not present in 3.3 - add 'regression' to keyword Feel free to come ask questions or to say hello in our QA chat: https://web.libera.chat/?settings=#libreoffice-qa Thank you for helping us make LibreOffice even better for everyone!
