NAME

       PDF::Builder::Resource::XObject::Image::PNM - support routines for PNM (Portable aNy Map) image library.
       Inherits from PDF::Builder::Resource::XObject::Image

   METHODS
           =new($pdf, $file, $name)

           Returns an image in the PDF. PNM types 1 (ASCII/plain bi-level/PBM), 2 (ASCII/plain grayscale/PGM), 3
           (ASCII/plain RGB/PPM), 4 (binary/raw bi-level/PBM), 5 (binary/raw grayscale/PGM), and 6 (binary/raw
           RGB/PPM) are supported.

           For bi-level, only values 0/1 (white/black) are supported. For grayscale, the maximum sample (full
           white) may be anything from 1 to 65535, with 0 being full black. If the maximum sample value is 255
           or smaller, one byte of raw binary data per pixel, otherwise two bytes. For RGB, each sample (full-on
           of that color) may be anything from 1 to 65535 (the same maximum for all three colors), with 0 being
           full black. If the maximum sample value is 255 or smaller, three bytes of raw binary data per pixel,
           otherwise six bytes.
