不保留PHP Imagick GIF动画 [英] PHP Imagick GIF Animation Is Not Preserved

问题描述

我上载gif并保持其动画有点麻烦.我的代码如下:

I am having a bit up trouble upload gifs and keeping their animation. My code looks like this:

$image = new Imagick($data['file']);
$object -> uploadFile('test.gif', $image -> getImageBlob());

使用getImageBlob()时，似乎没有保留gif. Ive事件尝试过:

And the gif goes not seem to be preserved when the getImageBlob() is used. Ive event tried:

$image = new Imagick($data['file']);
$image = $image->coalesceImages(); 
$image = $image->deconstructImages(); 
$object -> uploadFile('test.gif', $image -> getImageBlob());

使用getImageBlob()时是否可以预装gif?

Is there way I can preseve the gif when using getImageBlob()?

推荐答案

尝试 Imagick::getImagesBlob ，而不是 Imagick::getImageBlob . getImagesBlob将返回加载图像的顺序，而不是单个图像；在这种情况下，就是GIF中的每一帧.

Try Imagick::getImagesBlob instead of Imagick::getImageBlob. getImagesBlob will return the sequence of loaded images, as opposed to just a single image; in this case, the each frame in the GIF.

使用PHP 5.5.7和PECL imagick 3.1.2进行的快速检查揭示了两种不同的行为:

A quick check with PHP 5.5.7 and PECL imagick 3.1.2 reveals two different behaviors:

$image = new Imagick('test.gif');
var_dump(strlen($image->getImagesBlob())); // int(4316519)
var_dump(strlen($image->getImageBlob()));  // int(61413)
