NAME

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

   METHODS
       $res = PDF::Builder::Resource::XObject::Image::PNM->new($pdf, $file, %opts)
           Options:

           'name' => 'string'
               This is the name you can give for the PNM image object. The default is Nxnnnn.

           'compress' => 1
               This is the compression you can give for the PNM image object. Any value will
               cause the use of Flate compression, otherwise ("compress" not given),
               ASCIIHexDecode is used.

       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.
