wallcolor: Picky clicky color and set that as wallpaper

brontosaurusrex · 2022-02-01 15:21:01

a. Picky clicky color and set that as wallpaper.
https://raw.githubusercontent.com/bront … in/wallcol
Needs: gpick, imagemagick convert, nitrogen

b. Clicky twice to get gradient
https://raw.githubusercontent.com/bront … olGradient

Note: I'am assuming RGB colorspace is not the best for gradients, (read on HCL), but analogous colors works fine.
edit1: clean up.
edit2: will now automagically overlay ~/.noise.png, if there is one

c. Clicky 4 times to get gradient (a bit on the slow side)
https://raw.githubusercontent.com/bront … 2DGradient

~/.noise.png i'am using.

^ Oh this is gold! @brontosaurusrex

Grabbed both of them! For those that use feh, you can replace:

nitrogen --save --set-zoom-fill

with:

feh --bg-scale

Just, really really neat:)

^As usual, 3 minutes to script the thing and 2 hours to find imagemagick's cli (thats gives close to desired results).

Nice work bronto. Very nice indeed.

I have yet to try it, other things on the go.
Can you post the last one - clean - for download, That really caught my eye.
Thanks

@Sector: There are 3 scripts and one noise.png, latest versions always 5 posts up ^.

Since this friendly user has so far failed to return here and present the further development of @bronto's script/idea to the users in bunsenlabs as well, I want to do so glasses

wallcolor.conf -file

####################################
# configuration for 'wallcolor' #
####################################


### set wallcolor working directory:
walldir="$HOME/wallcolor"
#walldir="$HOME/Pictures/wallcolor"


### set desired resolution:
res="$(xdpyinfo | awk '/dimensions/{print $2}')"
#res="1920x1200"
#res="1600x900"
#res="1280x800"


### set file type [png] or [jpg]:
ext="png"
#ext="jpg"


### add noise to generated wall
### (make sure that ".noise.png" is in 'walldir' directory)
noise="true"
#noise="false"


### select your wallpaper application; --> [feh] or [nitrogen]:
#appl="nitrogen"
appl="feh"

The script is here in [beryllium] under /bin and the .conf - file I have under ~/.config
Works fine.

sleekmason · 2022-02-27 16:37:42

^ This is awesome! I made a couple of scripts that would work on my box, but nothing this neat:)

brontosaurusrex · 2022-02-28 15:29:13

b2. One more, ver b. extended to be a 4 clicker, twice for colors, twice for points to define gradient angle
https://raw.githubusercontent.com/bront … dientAngle
Needs: xdotool, gpick, imagemagick convert, nitrogen, bc

Nicely done:)

Really enjoying these.

johnraff · 2022-03-02 04:54:58

@bronto this wallpaper script has evolved way beyond a quick hint, so maybe could be split off into its own thread?

brontosaurusrex · 2022-03-02 08:48:22

^Sure.

johnraff · 2022-03-03 11:08:56

Done - please edit the topic title to taste smile

DeepDayze · 2022-03-03 15:06:15

This script is cool...going to play with it to make some nice dark backgrounds that use gradients. This should be perhaps packaged in say with bl utilities.
