NAME

       pamstack - stack planes of multiple PAM images into one PAM image

SYNOPSIS

       pamstack [-tupletype tupletype] [inputfilespec]

       All options may be abbreviated to the shortest unique prefix.

DESCRIPTION

       Reads  multiple  PAM or PNM images as input. Produces a PAM image as output, consisting of all the planes (channels) of the inputs, stacked
       in the order specified.

       The output is the same dimensions as the inputs, except that the depth is the sum of the depths of the inputs.  It  has  the  same  maxval.
       pamstack fails if the inputs are not all the same width, height, and maxval. The tuple type is a null string unless you specify the -tuple-
       type option.

       pamchannel does the opposite of pamstack: It extracts individual planes from a single PAM.

       Use pamtopnm to convert a suitable PAM image to a more traditional PNM (PBM, PGM, or PPM) image.

       One example of using pamstack is that some Netpbm programs accept as input a PAM that represents graphic image with  transparency  informa-
       tion  --  tuple  type  "RGBA".  In Netpbm, such images were traditionally represented as two images - a PPM for the color and a PGM for the
       transparency. To convert a PPM/PGM pair into PAM(RGBA) input that newer programs require, do something like this:

       pamstack -tupletype=RGBA myimage.ppm myalpha.pgm | pamtouil >myimage.uil

OPTIONS

       -tupletype tupletype
              This specified the tuple type name to be recorded in the output. You may use any string up to 255 characters. Some  programs  recog-
              nize some names. If you omit this option, the default tuple type name is null.
