NAME

       wmsetbg - sets the background on the X11 display

SYNOPSIS

       wmsetbg [-display display] [--update-domain domain|--update-wmaker] [options] [image]

DESCRIPTION

       wmsetbg  reads  the  specified  image (in any format supported by the WRaster library) and
       puts it on the root window. It can either scale the image or tile it to make  it  fit  the
       root  window.  Window  Maker  uses this command internally to set the root window image on
       start up.

OPTIONS

       --back-color|-b color
              the specified color is used as the background color for the texture.  Window  Maker
              temporary  sets  the  background  to  this  color  while loading and processing the
              texture.  You can specify colors using their X11 names or as an RGB triplet (either
              as  "rgb:RR/GG/BB" or "#RRGGBB") (reference to appropriate manpage should be here).
              In the later case color is a quoted string.

       --center|-e
              centers the image in the screen

       --colors|-c count
              limit the number of colors per channel to use for the image

       -display display
              connect to the X display

       --dither|-d
              enable color dithering on image

       --fillscale|-f
              scales the specified image to fill screen while preserving aspect ratio

       --help|-h
              print a help message with the list of options

       --match|-m
              use the best-matching-color  algorithm  when  converting  image  to  indexed  color
              palette

       --maxscale|-a
              scales the specified image to fit inside the screen preserving its aspect ratio

       --parse|-p texture
              parses the specified texture as a proplist style texture

       --scale|-s
              scales the specified image to fill the screen (default)

       --smooth|-S
              use a smooth scaling algorithm when resizing image

       --tile|-t
              tiles the specified image

       --update-domain|-D domain
              updates the specified domain database

       --update-wmaker|-u
              updates the Window Maker defaults database

       --version|-v
              print the version of Window Maker from which the program comes

       --workspace|-w workspace
              update background only for the specified workspace

       --xinerama|-X
              stretch image across Xinerama heads

INDEXED COLOR SCREENS

       If  your screen is not in a True Color configuration (generally sold as 16,777,216 colors)
       but in a indexed color mode (256 colors, 16 colors, ... which are  based  on  a  ColorMap)
       then  Window  Maker  may  need  to  process the image to convert it to a limited number of
       colors before using it for a background image.

       There are two options to choose what algorithm you want to use:

       --match or -m
              Search for the closest matching color  from  the  current  colormap;  this  is  the
              fastest algorithm but may lead to less good-looking result.

       --dither or -d
              Use  a  more  complex  algorithm  which  modify surrounding pixels to get a closer-
              looking color on average; this is slower but provides better looking images.

       If none is specified, then it is Window Maker's configuration choice that will be used.

       You can also use the option --colors to reduce the total number of colors from  the  image
       before  the  algorithm is applied.  The value specified with the option defines the number
       of possible values for each primary color (red, green  and  blue),  for  example  8  would
       reduce the image to use only 8*8*8=512 colors before applying the conversion algorithm.
