And thanks again for having shared the wallColGradient scripts from bunsenlabs ! They are now in my fluxbox menu and a quite funny addition. I guess with some customizations, and perhaps both scripts merged in one with one or two options could be in MXFB goodies ! an idea for @Jerry3904 ? ...
Meantime I merged the three wallcol scripts into one and renamed it ‘wallcolor’.
Also added a few arguments and options that are all set in a config file named ‘wallcolor.conf’
The script uses imagemagick, plus nitrogen or feh; these are all installed by default in mx-fluxbox.
It also needs ‘gpick’ (an advanced gnome colorpicker). This can be installed from MXPI and may need one or two additional gnome dependencies.
Place ‘wallcolor’ script in a directory of your choice, like "~/.local/bin/" or: "~/.fluxbox/scripts/" - and make the file executable...
Place 'wallcolor.conf' in '~/.config' directory. Then open 'wallcolor.conf' in a text-editor, to change settings/options to your preferences:
- working directory: --> currently set to: “$HOME/wallcolor”
- image resolution: --> currently set to read the current monitor resolution. Change if you prefer larger dimensions
- image file type: --> currently set to “png”. You can change to “jpg” to reduce filesize of the image.
- wallpaper setter: --> currently set to “nitrogen” (which is mxfb default). Alternatively you can use “feh”
If you want to have the option to add noise during image generation, then an overlay image named
“.noise.png” must be placed in the wallcolor working directory.
To generate a color wallpaper, use following command:
Code: Select all
# ( <-- single color )
path-to-wallcolor -f # example: ~/.local/bin/wallcolor -f
# ( <-- two-color gradient )
path-to-wallcolor -g2 # example: ~/.local/bin/wallcolor -g2
# ( <-- four-color gradient )
path-to-wallcolor -g4 # example: ~/.local/bin/wallcolor -g4
Note that the created background will be overwritten with each new wallpaper generated by this script. So be sure to rename the creation if you want to make it available for future background setting.
