我是这个GIF:
https://dl.dropboxusercontent.com/u/76885657/stackoverflow/2.gif
(透明背景)
使用此代码:
$im = new Imagick();
$im->readimage("example.gif");
$im->setImageAlphaChannel(11);
$im->setImageBackgroundColor('white');
$im->setImageFormat("jpg");
$im->stripImage();
$im->writeImage("example.jpg");
$im->clear();
$im->destroy();
结果:
https*://dl.dropboxusercontent.com/u/76885657/stackoverflow/3.jpg(without *)
(黄金背景)
但是想要这个:
https://dl.dropboxusercontent.com/u/76885657/stackoverflow/2.jpg
(白色背景)

我找到了它。是订单!:
$im = new Imagick();
$im->readimage("example.gif");
//错误
$im->setImageBackgroundColor('white');
$im->setImageAlphaChannel(11);
//写!!!
$im->setImageAlphaChannel(11);
$im->setImageBackgroundColor('white');
//其余代码......
$im->setImageFormat("jpg");
$im->stripImage();
$im->writeImage("example.jpg");
$im->clear();
$im->destroy();
