use Image::PNM;

$img->getpixel(1, 2);
$arr_ref = $img->bitmap;
# or
use Image::PNM qw/load_pnm/;
my $bitmap = load_pnm($filepath); # exported
# write file
use Image::PNM qw/write_pnm/;
~~~
# clone image
write_pnm('clone.ppm', $img->bitmap, $img->type, $img->bmax, "Some comments here"); # if bmax is not specified, default 255, comments is optional
write_pnm('image.pbm', $binarymap, 'P1', 'COMMENTS: in saving bitmap(P1, P4), bmax is not specified
Image::PNM is a light weight image interface for PNM formatted image file, which is ppm, pgm, pbm;
It can only load image or save image.
But lighter than other Image libraries.
