Prelight image fading effect
Last modified: 2017-06-12 10:41:14 UTC
Fade from "image1 to image2" (dreamy effect for prelight for example) OnMouseOver and fade back to image1 when mouse leaves, would be a very welcome addition to the Metacity feature set. I remember this effect being in KWin without causing any heavy cpu usage etc so I would think it's doable within the constrains of XFree. And idea could be extended to include fades such as "color1 to color2" although I think pixmap fades would be the neatest and easiest. Doable? If the effect already is in or this is a dup, sorry.
Should be fairly easy. I have a tracking bug for features that break the theme format, this bug should be marked as a blocker for that tracking bug.
Do we need to do this with the compositor?
There is nothing in this feature that require compositing.
Thanks. I wanted to be sure.
Another question: Does this really break the theme format? I mean, couldn't we just have a gconf setting that said "fade prelight? yes/no" rather than making it per theme?
Why would we want a preference for something like this?
Well, I was thinking that whether the prelight fades in or not wasn't really a property of the theme: it could be done or not done in any theme. So either we could do it all the time, or we could allow people to switch on or off whether they wanted it. Perhaps we could just use reduced-resources.
If there's to be any fading by default, I'd be fine with fading out on mouse-out, but would suggest to avoid fading in on mouse-over... you want immediate, snappy feedback when you mouse over something, and fade-ins can make things feel slow and imprecise. (IIRC this is how the tooltips behave on the Mac dock, for example.)
