Imagick SVG to JPG error no decode delegate

Question

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">

Is SVG a listed format in `\Imagick::queryformats();` ? You probably don't have an appropriate library to read SVG images installed such as RSVG. — Danack, Oct 05 '15 at 14:23
I see that SVG is not on the list, where can I find the right install files for RSVG — thegingerdk, Oct 06 '15 at 10:45
You haven't said what your system is. On centos it would be `yum install rsvg` probably. — Danack, Oct 06 '15 at 18:56
sorry about that, it's an ubuntu server, but I find that if I added the missing items to imagick it worked, — thegingerdk, Oct 07 '15 at 07:20
What was missing? I'm having this exact issue. Trying to base64 decdoe an svg to I can convert it to png — Native Coder, Oct 24 '16 at 21:30

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)

The shell renders the correct output from `identify -list format | grep SVG`, however I still received the `no decode delegate for this image format`... thoughts? – Shmack Oct 27 '20 at 21:58

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.

Worked for me. Thanks! (Ubuntu 18, PHP 7.4) – r34 Feb 20 '20 at 13:03
My svg contains that xml line :( – Shmack Oct 27 '20 at 22:00
Maybe check there is no extra white space around it? – Antony Oct 28 '20 at 10:28

I was able to fix this issue by installing inkscape.

apt-get install inkscape

Didn't work for me, unfortunately (Ubuntu 20.04). Thus, doesn't seem to be a universal solution. – twigmac Jan 18 '21 at 20:24
Installing inkscape worked for me in two environments. – r34 Aug 16 '21 at 13:46

Using Ubuntu 20.04, I ran the below command that installed the libmagickcore-6 package.

This package adds support for SVG, WMF, OpenEXR, DjVu and Graphviz to MagickCore. There are a few different versions, for instance, one of the versions is compiled for a channel depth of 16 bits with high dynamic range (Q16HDRI).

 sudo apt install libmagickcore-6*

With the above command, it seems like I installed all the different versions. Not sure if that's the best slash most efficient way, but it did take care of the issue.

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