具体代码如下:
<?php $i=imagecreatefromjpeg("photo3.jpg");//测试图片,自己定义一个,注意路径 for ($x=0;$x>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); //示例: echo $rAverage; ?>
