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

问题描述

我在上传 gif 和保留动画时遇到了一些麻烦.我的代码如下所示:

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());

当使用 getImageBlob() 时，gif 似乎没有保留.我已经尝试过事件:

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());

有没有办法在使用 getImageBlob() 时保留 gif?

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

推荐答案

尝试 <代码>Imagick::getImagesBlob 而不是 Imagick::getImageBlob.getImagesBlob 将返回加载图像的序列，而不是单个图像；在这种情况下，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.

快速检查 PHP 5.5.7 和 PECL imagick 3.1.2 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)
