CARD(9.1)							     CARD(9.1)

NAME
       card, ramp - create simple color	fields

SYNOPSIS
       fb/card [ -crgba	] [ -wx0 y0 x1 y1 ] red	[ green	blue ] [ alpha ]

       fb/ramp [ -v ] [	-wx0 y0	x1 y1 ]	[ [ leftcolor ]	rightcolor ]

DESCRIPTION
       Card  writes  a constant	(all pixels equal) picture on standard output.
       The red,	green blue and alpha arguments are numbers between 0 and  255.
       Green and blue default equal to red.  Alpha defaults to 255.  Option -c
       specifies the CHAN= attribute of	the  picture  file.   The  default  is
       CHAN=m,	CHAN=ma,  CHAN=rgb,  or	 CHAN=rgba  depending on which of red,
       green blue and alpha are	specified.

       Ramp creates a picture file whose pixel values range from leftcolor  to
       rightcolor  across  each	 scan line, writing on standard	output.	 Left-
       color defaults to 0; rightcolor defaults	to 255.	  If  three  arguments
       are  given  for leftcolor and rightcolor	the output will	have CHAN=rgb.
       Otherwise, it will have CHAN=m.

       Option -v causes	ramp to	make a vertical	ramp (leftcolor	 at  the  top,
       rightcolor at the bottom).

       For  both  commands,  option -w specifies the size of the picture.  The
       default gives WINDOW=0 0	1280 1024.
