PHP获取图片颜色值,检测图片主要颜色的代码:
view sourceprint?01
02$i=imagecreatefromjpeg("photo3.jpg");//测试图片,自己定义一个,注意路径
03for ($x=0;$x
04 for ($y=0;$y
05 $rgb = imagecolorat($i,$x,$y);
06 $r=($rgb >>16) & 0xFF;
07 $g=($rgb >> & 0xFF;
08 $b=$rgb & 0xFF;
09 $rTotal += $r;
10 $gTotal += $g;
11 $bTotal += $b;
12 $total++;
13 }
14}
15$rAverage = round($rTotal/$total);
16$gAverage = round($gTotal/$total);
17$bAverage = round($bTotal/$total);
18//示例:
19echo $rAverage;
