PHP は任意の画像の主要な色を抽出します

function dominant_color($image)
{
$i = imagecreatefromjpeg($image);
for ($x=0;$x for ($y=0) ;$y $rgb = imagecolorat($i,$x,$y);
 $r = ($rgb >> 16) & 0xFF;
 $g = ($rgb >> & 0xFF;
 $b = $rgb & 0xFF;
 $rTotal += $r;
 $gTotal += $g;
 $bTotal += $b;
 $total++;
 }
 }
$rAverage =round($rTotal/$total);
$gAverage =round($gTotal/$total);
$bAverage =round($bTotal/$total);
}
