问题


I have a string containing markup for an svg element.

<svg id="someId" width="300" height="300">
    <polygon id="another_id" fill="green" stroke="black" stroke-width="5" points="200,100 131,5 19,41 19,159 131,195 "></polygon>
</svg>

How can I read this string in Imagick and display it.

$svg = '<svg id="someId" width="300" height="300"><polygon id="another_id" fill="green" stroke="black" stroke-width="5" points="200,100 131,5 19,41 19,159 131,195 "></polygon>
</svg>';

$image = new Imagick();
// This is not working. 
$image->readImageBlob($svg);
$image->setImageFormat("png");
header("Content-Type: image/png");
echo $image;

How can I read this svg string so that I can proceed with doing other stuffs. Thanks

You have to add <?xml version="1.0"?> in the begining of $svg variable.

This code works for me:

$svg = '<?xml version="1.0"?><svg id="someId" width="300" height="300"><polygon id="another_id" fill="green" stroke="black" stroke-width="5" points="200,100 131,5 19,41 19,159 131,195 "></polygon></svg>';
$image = new Imagick();
$image->readImageBlob($svg);
$image->setImageFormat("png");
header("Content-Type: image/png");
echo $image;
