PHP Imagick breaks SVG on conversion to PNG

I'm updating a super legacy app and I'm trying to move from PHP 5.3 to PHP 5.6. Everything is going smoothly except for Imagick.

On old server we were using Imagick 3.0.0 and now on newer server with PHP 5.6 we tried using Imagick 3.6 and 3.7 but same problem occures. While trying to convert SVG graph to PNG it gets distorted.

Code used for testing is very simple:

$image = new Imagick();
$svg = 'GENERATED SVG';
$image->readImageBlob('<?xml version="1.0" encoding="UTF-8" standalone="no"?>'.$svg);
$image->setImageFormat('png24');
$image->writeImage('test.png');

I'm quite positive that SVG itself is fine, because I couldn't replicate this outcome on docker machine running similar config (PHP 5.6 and Imagick 3.7). Docker machine managed to covert SVG to PNG no problem. Chrome and other online SVG preview tools display the SVG correctly.

My SVG file:

I can't think of any reason why our server fails to convert this SVG to PNG.

Solution

It is the transform/rotate that annoys ImageMagic. If you wrap the <text> into a <g> and then transform/translate the <g> with the x,y position of the <text> and remove the x,y parameters form rotate it behaves.

I didn't test this, but you should probably replace the style attribute with the corresponding SVG attributes on <text>.

<svg version="1.1" xmlns="http://www.w3.org/2000/svg" width="2704" height="1330" viewBox="0 0 2704 1330">
  <rect fill="#FFF" x="0" y="0" width="2704" height="1330"></rect>
  <g transform="translate(35.357142857143 1086.742)">
    <text transform="rotate(270)" text-anchor="end" font-family="Verdana" font-size="29" font-weight="bold" fill="#000000">1</text>
  </g>
  <g transform="translate(80.357142857143 1086.742)">
    <text transform="rotate(270)" text-anchor="end" font-family="Verdana" font-size="29" font-weight="bold" fill="#000000">10</text>
  </g>
</svg>
