PCP(9.1)                                                              PCP(9.1)



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.
