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.

NAME

       pcp - copy pictures

SYNOPSIS

       fb/pcp [ -wx0 y0 x1 y1 ] [ -ox y ] [ -ttype ] [ -cchannels ] [ -Cchannels ] [ -mcolormap ] [ -M ] [ input [ output ] ]

DESCRIPTION

       Pcp  copies  the  input	picture (default standard input) to the output file (default standard output).	Options control the attributes and
       content of the output picture.

       -w x0 y0 x1 y1
	      causes only the given window of the input picture to be copied.  By default the whole picture is copied.

       -o x y causes the output picture's WINDOW= attribute to be translated by adding (x,y) to the input window coordinates.

       -t type
	      sets the TYPE= attribute of the output file.  The default is to use the input file's type.

       -c channels
	      causes only the given channels of the input picture to be copied.  The default is to copy all channels.  If channels not present	in
	      the  input  picture  are specified, they are computed in the ``most plausible'' way.  For example, a missing alpha channel is set to
	      255, and an m channel will be synthesized from rgb channels by computing NTSC luminance.	A 0 in channels causes a zero  channel	to
	      be written.

       -C channels
	      sets the output CHAN= attribute.	Channels must be the same length as the selected channels of the input picture.

       -m colormap
	      attaches the given color map to the output.

       -M     elides the color map from the output.
