Description J22Gim 2023-12-07 19:13:40 UTC
Description:
It would be great if there was an option to select a "fading pen" or "laser pointer" (not sure what the right name would be). This is simply a pen that fades in some seconds, thus making your remark transient (and therefore not ruining your slide if you still need to show it a bit more time).

Steps to Reproduce:
If you want to highlight/remark on something while showing a slide (maybe replying to a question about something you did not stress in the presentation), you have the option to mark it using the 'mouse as pen' option. You can also use this tool while presenting for the first time, depending on your style and choice.
However, everything that you do on the slide ends up kind of messing up the visuals of that particular slide.

Actual Results:
At that point, you have to right-click and select "Erase all ink on slide".

There are two problems with this:
1. It is a little bit of an interruption to the flow of the talk, and 
2. you either wait until you have a lot of 'ink' on the slide and then erase all of it, or you have to 'write and erase' many times.

Expected Results:
Both problems would be avoided if the ink disappeared by itself. This is, the ink stays only a few seconds, long enough to be seen by the audience (and thus, highlight your point), but at the same time it doesn't matter how much you scribble, your slide will eventually be clean again.


Reproducible: Always


User Profile Reset: No

Additional Info:
I shamelessly took this idea from another program: a neat online whiteboard application called ExcaliDraw (www.excalidraw.com). In that application, you can select something called 'laser pointer' (which I think is a good name!) which will draw a line that fades out after 2-3 seconds (and it does so very elegantly following the same trajectory used by the pointer). You can see how it works in the attached video. It is open source and we should give them credit.

I think it would be a very nice addition to Impress.
Thanks for all your work and let's continue improving LO!!


Note: if you have VLC you may see an empty video. Try disabling 'hardware decoding' or use another video player.

Thanks for the suggestion. This is already tracked in bug 96886, so marking as duplicate.
Please feel free to comment about the "trailing" aspect there if you feel it is needed.
