A miscellaneous collection of commands to perform specific tasks
Sometimes, images I want to use as wallpapers are too bright. To “dim” them, you can do:
convert <file> -modulate <value> <new-file>Here, convert is an imagemagick utility. <value> is made up of three values:
brightness, saturation and hue. Therefore, to achieve the effect of “dimming” an
image, you would set <value> to something like 40,50,100.
