PIXHIST(1)			    BRL-CAD			    PIXHIST(1)

NAME
       pixhist - display a histogram of	a color	pix file on a framebuffer

SYNOPSIS
       pixhist [-v] [file.pix]

DESCRIPTION
       Pixhist displays	a histogram of the pixel values	of the given pix(5)
       format file, or,	if no file is specified, will read from	standard in.
       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.

       The relative frequency is displayed on the x axis scaled	so that	the
       maximum is full screen. The value 0 is at the bottom of the screen, 255
       is at the top. All three	colors will be drawn on	each scan line,	and
       all are scaled by the same factor.  The output is overlaid on whatever
       is currently on the display.

       The -v flag will	also output the	histogram values on the	terminal.
