AsposeFontConvertToSVG

How to convert the font into SVG format?

1. Create a ‘FileReader’.
2. Call AsposeFontConvertToSVG function.
3. The resulting file name is set, in json.fileNameResult.
4. Next, if the json.errorCode is 0, then you can get links to the result files. If the json.errorCode parameter is not equal to 0 and, accordingly, there will be an error in your file, then information about such an error will be contained in the json.errorText.
5. Now, the DownloadFile function generates a link and allows you to download the resulting file to the user’s operating system.

Below is the code example for the EOT to SVG conversion.

  var fEOT2SVG = function (e) {
    const file_reader = new FileReader();
    file_reader.onload = (event) => {
      const json = AsposeFontConvertToSVG(event.target.result, e.target.files[0].name, Module.FontType.OTF);
      if (json.errorCode == 0) document.getElementById('output').textContent = json.fileNameResult;
      else document.getElementById('output').textContent = json.errorText;
      DownloadFile(json.fileNameResult, "font/ttf");
    }
    file_reader.readAsArrayBuffer(e.target.files[0]);
  }

Web Worker example:

  /*Create Web Worker*/
  const AsposeFontWebWorker = new Worker("AsposeFontforJS.js");
  AsposeFontWebWorker.onerror = evt => console.log(`Error from Web Worker: ${evt.message}`);
  AsposeFontWebWorker.onmessage = evt => document.getElementById('output').textContent = 
    (evt.data == 'ready') ? 'library loaded!' :
      (evt.data.json.errorCode == 0) ? `Result:\n${DownloadFile(evt.data.json.fileNameResult, "font/ttf", evt.data.params[0])}` : `Error: ${evt.data.json.errorText}`;

  /*Event handler*/
  const fEOTtoSVG = e => {
    const file_reader = new FileReader();
    file_reader.onload = event => {
      /*Convert a OTF fonts to TTF and save - Ask Web Worker*/
      AsposeFontWebWorker.postMessage({ "operation": 'AsposeFontConvertToSVG', "params": [event.target.result, e.target.files[0].name, 'Module.FontType.OTF'] }, [event.target.result]);
    };
    file_reader.readAsArrayBuffer(e.target.files[0]);
  };

  /*Make a link to download the result file*/
  const DownloadFile = function (filename, mime, content) {
      mime = mime || "application/octet-stream";
      var link = document.createElement("a"); 
      link.href = URL.createObjectURL(new Blob([content], {type: mime}));
      link.download = filename;
      link.textContent = filename;
      link.title = "Click here to download the file";
      document.getElementById('fileDownload').appendChild(link);
      document.getElementById('fileDownload').appendChild(document.createElement("br"));
  }
