NAME
       fbclear - clear a frame buffer image

SYNOPSIS
       fbclear [-c] [-F	framebuffer] [red green	blue]

       fbclear [-c] [-F	framebuffer] [gray_value]

DESCRIPTION
       Fbclear is used to erase	a frame	buffer using whatever method is
       efficient for the device	being accessed.	By default, the	selected color
       will be flooded into the	color planes. If the -c	option is used,	a
       standard	linear colormap	will be	loaded and the pan and zoom values
       will be reset.

       If the optional color values are	given, fbclear writes the specified
       color over the entire image. The	color values must be in	the range 0 to
       255. In the second form shown above, the	single gray_value is written
       into all	three color channels.

       The frame buffer	to be cleared is determined from the -F	option if
       given. Otherwise	the environment	variable

       FB_FILE is used to select the display device (see brlcad(1)). If	this
       variable	is not set, the	default	device for your	system will be used.

       In addition to those flags shown	above, the -W~A width -N~A height	and
       -S~A square_size flags can be used to set	the size of the	output frame
       buffer.
