NAME
pcp - copy pictures
SYNOPSIS
fb/pcp [ -wx0 y0 x1 y1 ] [ -ox y ] [ -ttype ] [ -cchannels ] [ -Cchan‐
nels ] [ -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 chan‐
nel 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.
