wmsetbg(1)                  General Commands Manual                 wmsetbg(1)

       wmsetbg - sets the background on the X11 display

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

       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.

       --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.

              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

              enable color dithering on image

              scales the specified image to fill screen while preserving
              aspect ratio

              print a help message with the list of options

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

              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

              scales the specified image to fill the screen (default)

              use a smooth scaling algorithm when resizing image

              tiles the specified image

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

              updates the Window Maker defaults database

              print the version of Window Maker from which the program comes

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

              stretch image across Xinerama heads

       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

       --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
