NAME

       ppmtoppm - copy PPM image

SYNOPSIS

       ppmtoppm

DESCRIPTION

       This program is part of Netpbm(1).

       ppmtoppm  simply copies a PPM image from Standard Input to Standard Output.  This may seem
       an unnecessary duplication of cat, but remember that a PPM program can read a PBM  or  PGM
       image,  and  the right kind of PAM, as if it were PPM.  So ppmtoppm can read either a PBM,
       PGM, or PPM image and produce a PPM image as output.

       Even that is of limited usefulness because of the fact that almost any  program  to  which
       you  would  feed the resulting PPM image could also just take the original image directly.
       However, sometimes you really need a true PPM image.

       When you know you have a PGM image and want a PPM image, pgmtoppm is a more general way to
       do that conversion.  When you know you have a PBM image, use that and pbmtopgm.

       options common to all programs based on libnetpbm (See
        Common Options ⟨index.html#commonoptions⟩ .)
