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 coordi-
nates.
-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 speci-
fied, 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 pic-
ture.
-m colormap
attaches the given color map to the output.
-M elides the color map from the output.
