In the Mandelbrot plasma wallpaper, it would be nice if the configuration showed you the coordinates and zoom level of the current view, so you can write down interesting places for future reference as well as share them between users.

I know that would be nice, I wanted to add that as a context menu (right click on wallpaper) as IMHO that would clutter the configuration UI; but plasma doesn't currently allow wallpapers to have their own actions. Perhaps in 4.4...
Meanwhile, you can find (and even change) the coordinates by editing the plasma-desktop-appletsrc config file.

Code: Select all

bjacob@kiwi:~> grep mandelbrot .kde4/share/config/plasma-desktop-appletsrc
wallpaperplugin=mandelbrot
[Containments][1][Wallpaper][mandelbrot]
mandelbrotcenter=-1.25677663435567,-0.379207012956942
mandelbrotcolor1=0,0,0
mandelbrotcolor2=255,255,255
mandelbrotcolor3=0,0,255
mandelbrotlock=2
mandelbrotquality=4
mandelbrotzoom=2.7125284135687e-09


The relevant keys are mandelbrotcenter and mandelbrotzoom. The zoom means the half-width of the view in complex coordinates.

Hi, I found this blog:
http://yuenhoe.co.cc/blog/2009/10/next- ... l-actions/

looks like plasma now allows wallpapers to add their own actions (that is, right-click menu entries).

So if you want to do it yourself, go ahead, you have my green light and I'll provide you guidance. You still have 2 weeks before the soft 4.4 freeze to add that to the feature plan, and more time before the hard freeze to do that.

Otherwise, I can't do it now (no time) but i might do it for KDE 4.5.

Another useful action would be "export image", export as PNG and perhaps also as JPG.

Hi, I just implemented this in trunk. Will appear in KDE 4.5. You can export/import the view parameters to/from simple text files, and by the way you can also export PNG images.

Can some Brainstorm moderator mark this as "done" ? I don't seem to have the access rights.

By the way: Mandelbrot is massively improved in KDE 4.5, faster, better rendering, better user interaction.

Thanks!

Here are Mandelbrot settings that give pretty good results. Just paste this into a file with extension ".txt" then right click on desktop and do "Import Mandelbrot settings..."
