title: ImageMagick convert command Unable to Read Font
body: <p>I'm integrating an ImageMagick command into a Firebase Function written in Node.js. I already have Ghostscript installed and have a full list of fonts available:</p>
  
  <pre><code>convert -list font
  
  Path: /usr/local/Cellar/imagemagick/7.0.8-10/etc/ImageMagick-7/type-apple.xml
    Font: AndaleMono
      family: Andale Mono
      style: Undefined
      stretch: Undefined
      weight: 0
      glyphs: /Library/Fonts//Andale Mono.ttf
    Font: AppleChancery
      family: Apple Chancery
      style: Undefined
      stretch: Undefined
      weight: 0
      glyphs: /Library/Fonts//Apple Chancery.ttf
    Font: AppleMyungjo
      family: AppleMyungjo
      style: Undefined
      stretch: Undefined
      weight: 0
      glyphs: /Library/Fonts//AppleMyungjo.ttf
  </code></pre>
  
  <p>Here's my code:</p>
  
  <pre><code>exec(`convert ${tempFilePath} -font /Users/emma/Library/Fonts/Nunito-Regular.ttf -fill white -pointsize 60 -gravity center -draw "text 0,300 'this is a label'" ${tempFilePath}`, {stdio: 'ignore'}, (err, stdout) =&gt; {
           if (err) {
               console.error('Failed to label image.', err);
               reject(err);
           } else {
               resolve(stdout);
           }
  });
  </code></pre>
  
  <p>I also tried:</p>
  
  <pre><code>exec(`convert ${tempFilePath} -font Arial -fill white -pointsize 60 -gravity center -draw "text 0,300 'this is a label'" ${tempFilePath}`, {stdio: 'ignore'}, (err, stdout) =&gt; {
         if (err) {
            console.error('Failed to label image.', err);
            reject(err);
         } else {
            resolve(stdout);
         }
  });
  </code></pre>
  
  <p>The error I'm getting is:</p>
  
  <pre><code>convert: unable to read font `/Library/Fonts//Andale' @ warning/annotate.c/RenderType/872
  </code></pre>
