DESCRIPTION

       fvwm-root  reads  the image file specified in the command line and displays it in the root
       window.  The supported image formats are XBM, XPM, PNG and SVG if  appropriated  libraries
       are compiled in.

       SVG  rendering  options    (as described in the  ICONS AND IMAGES section of the main fvwm
       documentation) can be utilized.

OPTIONS

       These command line options are recognized by fvwm-root:

       --retain-pixmap | -r
              Causes fvwm-root to retain and publish the Pixmap with  which  the  background  has
              been  set  (the  ESETROOT_PMAP_ID  and _XROOTPMAP_ID properties are used).  This is
              useful for applications which want to use the root  Pixmap  on  the  background  to
              simulate  transparency  (for example, Eterm and Aterm use this method). This option
              should also be used for the RootTransparent colorset option, refer to the COLORSETS
              section  of  fvwm(1).   If this option is not used, fvwm-root sets the _XSETROOT_ID
              property to None, and some programs, like fvwm modules,  may  use  this  to  update
              their background if the background is transparent (Transparent colorset).

              Note,  a  well  behaved  program, like fvwm, should listen to both _XSETROOT_ID and
              _XROOTPMAP_ID property changes and update  itself  correspondingly.   However  some
              programs  listen  only  to one of them, so you should either use this option or not
              depending on what part is implemented by these programs.  You should also use  this
              option to get fast root-transparent menus in fvwm.

       --no-retain-pixmap
              This is a default. May be useful to explicitly force the default even if "--retain-
              pixmap" is specified earlier.

       --dummy | -d
              Causes fvwm-root NOT to set the background, but to only free  a  memory  associated
              with the ESETROOT_PMAP_ID property (if any).  In any case the _XSETROOT_ID property
              is set to None.

       --no-dummy
              This is a default. May be useful to explicitly force the default even if  "--dummy"
              is specified earlier.

       --dither
              Causes  fvwm-root  to dither images for "smoother" rendition on displays with color
              depth of 16 or lower. This the default with color depth  less or equal to 8.

       --no-dither
              Causes fvwm-root NOT to dither images. This is the default with color depth greater
              than 8.

       --color-limit ncolors
              Causes  fvwm-root  to limit its color use to ncolors (if specified). This option is
              taken in account only with color depth  less or equal to  8  (and  a  TrueColor  or
              GrayScale visual). The default is to use the same color limit as fvwm. So in normal
              situation this option is not useful. However, if fvwm use a private colors map,  as
              fvwm-root always use the default colors map you should use this option for limiting
              colors correctly. If ncolors is not specified a default is used.

       --no-color-limit
              Causes fvwm-root NOT to limit its color use.

       --help Shows a short usage.

       --version
              Shows a version number.

COMPATIBILITY

       In the past this utility was called xpmroot.  This name is still supported as a symlink.

BUGS

       Repeated use of fvwm-root with different xpm pixmaps will use up slots in your color table
       pretty darn fast.
