in thread Image anti-aliasing using GD and Image::Magick

Thank you for your advice.
I think i can get good results creating a larger image and then scaling it down with something like this:

#this is the default example for GD::Graph3D
use GD::Graph::bars3d;
use Image::Magick;

my @data = ( 
       ["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"],
       [ 1203,  3500,  3973,  2859,  3012,  3423,  1230]
    );

my $graph = new GD::Graph::bars3d( 800, 600 ); #BIG image

    $graph->set( 
        x_label           => 'Day of the week',
        y_label           => 'Number of hits',
        title             => 'Daily Summary of Web Site',
    );
my $gd = $graph->plot( \@data );

#here the interesting part
my $image=Image::Magick->new(magick=>'png');
$image->BlobToImage($gd->png);
$image->Resize(width=>400, height=>300); #small and anti-aliased one
$image->Write('graph3d.png');
