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 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 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.
