PHP获取图片主要颜色RGB代码

1. $i = imagecreatefromjpeg("image.jpg");
3. for ($x=0;$x<imagesx($i);$x++) {
4. for ($y=0;$y<imagesy($i);$y++) {
5. $rgb = imagecolorat($i,$x,$y);
6. $r = ($rgb >> 16) & 0xFF;
7. $g = ($rgb >> & 0xFF;
8. $b = $rgb & 0xFF;
10. $rTotal += $r;
11. $gTotal += $g;
12. $bTotal += $b;
13. $total++;
14. }
15. }
17. $rAverage = round($rTotal/$total);
18. $gAverage = round($gTotal/$total);
19. $bAverage = round($bTotal/$total);
