fvwm-root(1)			 FVWM Modules			  fvwm-root(1)

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 dis‐
       plays it in the root window.  The supported image formats are XBM,  XPM
       and PNG if appropriated libraries are compiled in.

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 trans‐
	      parency  (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 (Trans‐
	      parent 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 depend‐
	      ing  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  explicitely  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 explicitely 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 speci‐
	      fied). 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 pri‐
	      vate 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  sup‐
       ported as a symlink.

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