Description: It is actually possible to save annotations made during presentation with the mouse pointer if the option "Mouse painter as pen" (in Slide Show Settings) has been enabled before starting the presentation. The problem is however that the tool doesn't use the algorithm of the normal hand-writing tool used in slide editing mode: while in editing mode the hand-writing tool saves just a few dots and "builds" Bézier curves, in presentation mode the algorithm just save LOTS of micro points. You can see an example in the attached screenshot and odp file: the curves in blue has been obtained with the handwriting tool in editing mode, those in red with the "same" (that is not) tool in the presentation mode. The result is that even with a few annotations, the slides become unresponsive even on modern pc and generate other problems (e.g., annotation saved on the wrong slide) Steps to Reproduce: 1. In Slide Show Settings choose the option "Mouse painter as pen" 2. Now starts a presentation and make a few annotations 3. Close (or end) the presentation Actual Results: Annotation are now saved (as desired) with the slide but making too many points but are composed of way too many points that make instable LO (i.e., needs to be killed). Annotations may also appear on wrong slides. Expected Results: The annotations made during presentation should have used the same algorithm of hand writing during slide edit. Reproducible: Always User Profile Reset: No Additional Info: A similar bug already exists (https://bugs.documentfoundation.org/show_bug.cgi?id=51928), but it focus on presentation annotations not being saved. While this one observes that annotations can actually be saved, but the process of creating them is bugged. There is no easy workaround, so I leave this bug report as normal.

Hello, I know it's not nice to ping a bug report without bringing any news, but this bug is pretty important for me as it would allow me to use LibreOffice for teaching in distant learning projects, and at the same time it should be fairly simple to solve for someone with knowledge of the internals of LO Draw, as it is a matter of applying an already know algorithm in the context of live slide annotations. Is there any way I could investigate this bug further or be more precise in its description?

I think the description is clear enough, so the only way you could help is to dig into the code and provide a better algorithm. I don't believe this is a regression, I assume it has always behaved like this.
Dear Antonello, 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 http://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://kiwiirc.com/nextclient/irc.freenode.net/#libreoffice-qa Thank you for helping us make LibreOffice even better for everyone!

It's really a pity this bur remains somehow hidden in the mass, as it is pretty serious for me, as it prevents me from using libreoffice to realise distance learning courses...
In https://cgit.freedesktop.org/libreoffice/core/commit/?id=631964a2ce1da3fbbeb53a5550c0e6728ba644aa I have changed the creation of the persistent drawing so, that now the points which belong to one pen move in slideshow are in one object in edit mode. That does not solve the problem, that too many points are generated, but the handling is now easier in edit mode. Generating of points is somehow related to time. When you move the mouse quickly, you get less points than moving the mouse slowly. Generating of the points is located in virtual bool handleMouseDragged( const awt::MouseEvent& e ) in https://opengrok.libreoffice.org/xref/core/slideshow/source/engine/slide/userpaintoverlay.cxx?r=91ba9654#358
Thank you @Regina.. Is there any nightly build one can use on Linux to test? As a general note, why reinvent the weheel and not just reuse the handwriting tool of slide editing ?

At the moment the daily builds are not being generated, but hopefully they will come back soon: https://dev-builds.libreoffice.org/daily/master/current.html
Regina Henschel committed a patch related to this issue. It has been pushed to "master": https://git.libreoffice.org/core/commit/44c0f2da567b49ef8a539958a834f1bc841c2003 tdf#112687 Simplify polylines from slideshow annotations It will be available in 24.2.0. The patch should be included in the daily builds available at https://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More information about daily builds can be found at: https://wiki.documentfoundation.org/Testing_Daily_Builds Affected users are encouraged to test the fix and report feedback.
The patch reduces the amount of points. I know, that these patches are only a workaround, but I think it is better than the current state in LO 7.6. Because it is only a workaround, I will not set this issue to fixed. (In reply to Antonello from comment #12) > Thank you @Regina.. > Is there any nightly build one can use on Linux to test? > > As a general note, why reinvent the wheel and not just reuse the > handwriting tool of slide editing ? I don't know how to do it. The problem is, that the drawing happens in slideshow mode whereas the handwriting tool is used in edit mode. The "mouse as pen" tool is very old. There might be a reason, why the handwriting tool was not use although that already exists at that time.
(In reply to Regina Henschel from comment #15) > Because it is only a workaround, I will not set this issue to fixed. Hi Regina, I tested your fix for this issue and it works quite well. Thanks. The only thing I'd like to suggest is that the final set of lines be grouped together. With the current implementation, after the user exits the presentation and clicks the annotation shapes, they end up moving just a line segment. It would be nice to have all of these segments grouped... what do you think?

It should behave now so, that a line which the user has drawn with one mouse movement will become one object. If the user releases the mouse button a new line starts. That is similar to how the freeline tool works. Does it not behave that way for you? Could you please attach in that case the file the user gets after leaving presentation mode? > > It would be nice to have all of these segments grouped... what do you think? I have not considered such. However, I think it is possible.

You're right, it now works as the freeline tool now, which is the expected behavior. > I have not considered such. However, I think it is possible. The advantage of this is that when the user draws something that is not a single line (f.i. an arrow, or a word), then all of these lines are grouped together.
