PHP obtains the color value of the image and detects the main color code of the image:
view sourceprint?01
02$i=imagecreatefromjpeg("photo3.jpg");//Test picture, define one yourself, pay attention to the path
03for ($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//Example:
19echo $rAverage;
20?>
