NAME

       pnmpaste - paste a rectangle into a portable anymap

SYNOPSIS

       pnmpaste [-replace|-or|-and |-xor] frompnmfile x y [intopnmfile]

DESCRIPTION

       Reads two portable anymaps as input.  Inserts the first anymap into the second at the specified location,
       and produces a portable anymap the same size as the second as  output.   If  the  second  anymap  is  not
       specified,  it  is  read  from  stdin.   The  x and y can be negative, in which case they are interpreted
       relative to the right and bottom of the anymap, respectively.

       This tool is most useful in combination with pnmcut.  For instance, if you want to edit a  small  segment
       of  a large image, and your image editor cannot edit the large image, you can cut out the segment you are
       interested in, edit it, and then paste it back in.

       Another useful companion tool is pbmmask.

       pnmcomp is, a more general tool, except that it lacks the "or,"  "and,"  and  "xor"  functions.   pnmcomp
       allows  you  to  specify an alpha mask in order to have only part of the inserted image get inserted.  So
       the inserted pixels need not be a rectangle.  You can also have the inserted image be translucent, so the
       resulting image is a mixture of the inserted image and the base image.

       The  optional  flag  specifies  the operation to use when doing the paste.  The default is -replace.  The
       other, logical operations are only allowed if both input images are bitmaps.  These operations act as  if
       white is TRUE and black is FALSE.

       All flags can be abbreviated to their shortest unique prefix.
