slideshow

a simple cli application to start a background image slideshow using 'feh'.

requirements

configuration is entirely done via environment variables.

variable	default	description
SLIDESHOW_INTERVAL	60	the interval of the slideshow in seconds
SLIDESHOW_DIRECTORY	"$HOME"	path to a directory containing images
SLIDESHOW_SCANINTERVAL	60	the interval for directory scans in seconds
SLIDESHOW_TMPFILE		path to a temporary file
SLIDESHOW_RESOLUTION		the resolution to which images are scaled (i.e. 1920x1080)
SLIDESHOW_PALETTE		path to a file where the color palette will be stored
SLIDESHOW_PALETTE_ALGORITHM	"wsm"	the algorithm used to generate the color palette
SLIDESHOW_PALETTE_COLORS	16	the amount of colors generated
SLIDESHOW_LOGLEVEL	"info"	the log level

note:

if SLIDESHOW_RESOLUTION is unset the images will be displayed as they are (without any scaling).
if SLIDESHOW_TMPFILE is set a temporary file will be used instead of keeping the image internally buffered. this could be useful on systems with limited ram.
