in reply to Create image from pixel values with Imager

Unfortunately raw_datachannels doesn't follow raw_storechannels, so if you supply one, you probably need to supply the other, this also lets you switch to pack "C*" to pack the data as bytes. I don't have your data, so I can't check this does exactly what you want.

my $img = Imager->new( type => 'raw', xsize => 256, ysize => 256, data => pack('C*', @data), raw_interleave => 0, raw_storechannels => 1, raw_datachannels => 1, model => 'gray' ); $img->write(file=>'data.png');
