       ppmtoppm - copy PPM image




       This program is part of Netpbm(1).

       ppmtoppm simply copies a PPM image from Standard Input to Standard Out-
       put.  This may seem an unnecessary duplication  of  cat,  but  remember
       that  a  PPM program can read a PBM or PGM image 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.
