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.
