PHP Gets the Color Value of an Image_PHP Tutorial

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?>
