Imagick not using custom fonts when converting SVG to JPG with PHP

Question

I'm having an issue with custom fonts not rendering when attempting to convert an SVG to a JPG image. I am using font-family="Lobster" defined for an SVG text element.

My server setup is as follows:

• CentOS 6.5 (32 bit)
• ImageMagick 6.5.4-7
• PHP 5.2.17

The PHP code I am testing with, but does not work. I am attempting to use the custom font Lobster.

//Setup SVG to be read by Imagick.
$SVG = '<?xml version="1.0" encoding="utf-8"?>';
$SVG .= '<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">';
$SVG .= '<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="158px" height="92px" viewBox="0 0 158 92" enable-background="new 0 0 158 92" xml:space="preserve">';
$SVG .= '<text transform="matrix(1 0 0 1 32 58)" font-family="Lobster" font-style="normal" font-size="20px" font-weight="400">Lobster</text>';
$SVG .= '</svg>';

$image = new Imagick();

//Convert SVG to JPG
$image->readImageBlob($SVG);
$image->setImageFormat("jpeg");

//Save the thumbnail.
$save_path = '/home/username/lobster.jpg';
$image->writeImage($save_path);


echo '<img src="lobster.jpg" alt="" /><br />';

Which produces the following image:

What I have tried:

I've created a type.xml file located at /home/username/.magick/type.xml with the Lobster font definition as shown here:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE typemap [
<!ELEMENT typemap (type)+>
<!ELEMENT type (#PCDATA)>
<!ELEMENT include (#PCDATA)>
<!ATTLIST type name CDATA #REQUIRED>
<!ATTLIST type fullname CDATA #IMPLIED>
<!ATTLIST type family CDATA #IMPLIED>
<!ATTLIST type foundry CDATA #IMPLIED>
<!ATTLIST type weight CDATA #IMPLIED>
<!ATTLIST type style CDATA #IMPLIED>
<!ATTLIST type stretch CDATA #IMPLIED>
<!ATTLIST type format CDATA #IMPLIED>
<!ATTLIST type metrics CDATA #IMPLIED>
<!ATTLIST type glyphs CDATA #REQUIRED>
<!ATTLIST type version CDATA #IMPLIED>
<!ATTLIST include file CDATA #REQUIRED>
]>
<typemap>

  <type
     format="ttf"
     name="Lobster"
     fullname="Lobster"
     family="Lobster"
     glyphs="/home/username/fonts/Lobster/Lobster.ttf"
     style="normal"
     stretch="normal"
     weight="400"
     />

</typemap>

I've included a direct include in the /usr/lib/ImageMagick-6.5.4/config/type.xml file like this:

<typemap>
   <include file="type-ghostscript.xml" />
   <include file="/home/username/.magick/type.xml" />
</typemap>

When outputting the fonts using the $image->queryfonts(); method, I can see the Lobster font defined in the list. For example, this:

$image = new Imagick();
$fonts = $image->queryfonts();
foreach($fonts as $font) {
    echo $font . '<br />';
}

Returns this:

[...]
Hershey-Plain-Triplex-Regular
Hershey-Script-Complex-Regular
Hershey-Script-Simplex-Regular
Lobster
MeriendaOne
NewCenturySchlbk-Bold
NewCenturySchlbk-BoldItalic
NewCenturySchlbk-Italic
NewCenturySchlbk-Roman
[...etc]

Additionally, I believe ImageMagick is using it's own internal SVG renderer. The shell command:

convert -list format | grep SVG

Returns:

MSVG  SVG       rw+   ImageMagick's own SVG internal renderer
SVG  SVG       rw+   Scalable Vector Graphics (RSVG 2.26.0)
SVGZ  SVG       rw+   Compressed Scalable Vector Graphics (RSVG 2.26.0)

Any ideas as to why this isn't working?

Answer 1

I was having the same problem converting SVG to PNG using Imagemagick but was unable to make it work using that approach. I was somehow able to get the result I need using docraptor:

 DocRaptor.createAndDownloadDoc("YOUR_API_KEY", {
    test: true, // test documents are free, but watermarked
    type: "pdf",
    document_content: document.getElementById('container_of_svg').innerHTML
  }) 

Just make sure to add the font declarations inside the container_of_svg element like below and make sure to add an absolute URL to your fonts:

@font-face {
    font-family: 'DaimlerCS-Demi';
    src: url("https://staging.xxx.com/xx/fonts/xx/FontCS-Demi.eot")
}
page {
      size: 21.16cm 15.87cm;
      padding: 1cm;
      margin:0;
      background: #E6E6E6;
}

Just check their document here: https://docraptor.com/documentation/jquery

Note: docraptor is not free but if your client can pay for it, I think its a solid option.
