用Imagick PHP调整动画GIF图像大小

Question

I wants to resize animated GIF images without loosing animation. Resize process is working fine but after resize animation goes away. Please check my script in-line if i am doing anything wrong

Version: ImageMagick 6.9.1-1 PECL Imagick Extension - 3.1.2

$images = $this->imageObj->coalesceImages();
foreach ($images as $frame) {
 $frame->thumbnailImage($this->thumbWidth, $this->thumbHeight);
 $frame->setImagePage($this->thumbWidth, $this->thumbHeight, 0, 0);
}

$this->imageObj = $images->deconstructImages();
$this->imageObj->writeImage($this->thumbImagePath);

See this answer . From the link:

If you have imagemagick access, you can do this:

 system("convert big.gif -coalesce coalesce.gif"); system("convert -size 200x100 coalesce.gif -resize 200x10 small.gif");
