NAME

       fvwm-root - Sets the root window of the current X display to image

SYNOPSIS

       fvwm-root [--retain-pixmap|-r] [--no-retain-pixmap] [--dummy|-d] [--no-
       dummy] [--dither] [--no-dither] [--color-limit [ncolors] ] [--no-color-
       limit] [--help|-h|-?]  [--version|-V] image_file

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 defaut 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.
