php - Imagick SVG 到 JPG 错误无解码委托(delegate)

Question

我尝试了许多不同的解决方案，但无法使用 Imagick::readImageBlob，我们将不胜感激。

错误信息:

Caught exception: no decode delegate for this image format `' @ error/blob.c/BlobToImage/364

代码:

$svg = file_get_contents($this->svg);
$image = new Imagick();
$image->readImageBlob($svg);
//...

SVG:

<?xml version="1.0" encoding="UTF-8" standalone="no"?> 
    <svg xmlns:xlink="http://www.w3.org/1999/xlink" xmlns="http://www.w3.org/2000/svg" version="1.1" width="928" height="933" id="parent">

对我来说，这些部门不见了(ubuntu 16.04):

sudo apt-get install libgraphicsmagick1-dev libmagickcore-dev libmagickcore-6.q16-2 libmagickcore-6.q16-2-extra
