Imagick SVG to JPG error no decode delegate

问题


I have tried many different solutions, but cannot use Imagick::readImageBlob, any help would be appreciated.

Error message:

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

Code:

$svg = file_get_contents($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">

        <image width="928" height="933" xlink:href="image.jpg" ></image>

After having tried by @Native Coder and @karser answers my SVG was still generating the same no decode delegate error. It worked after I added <?xml version="1.0" encoding="UTF-8" standalone="no"?> as the opening line of my SVG content. Worth checking your XML is valid as well.

For me these deps were missing (ubuntu 16.04):

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

The expected output:

identify -list format | grep SVG
     MSVG  SVG       rw+   ImageMagick's own SVG internal renderer
      SVG  SVG       rw+   Scalable Vector Graphics (RSVG 2.40.13)
     SVGZ  SVG       rw+   Compressed Scalable Vector Graphics (RSVG 2.40.13)

To anyone reading this in the future, I had this exact same issue. The problem was that I was missing libxml2 and librsvg2-bin.




回答4:


I was able to fix this issue by installing inkscape.

apt-get install inkscape
