Add array items in XMP metadata of EPS| JavaScript

To add array items in XMP metadata of EPS file, it is necessary to do several steps:

1. Create file reader ‘const file_reader = new FileReader();’ and read file ‘file_reader.readAsArrayBuffer(e.target.files[0]);’.
2. On load event handler call AsposeXMPAddArrayItem and pass the file content, his name, and the result file name to it.
3. If the EPS file doesn’t contain XMP metadata, we get a new one filled with values from PS metadata comments (%%Creator, %%CreateDate, %%Title, etc).
4. The result JSON contains the file name in fileNameResult and gets metadata in the XMP element.
5. You can download files by using the DownloadFile function: ‘DownloadFile(JSON.fileNameResult, “image/pdf”);’ and display the result ‘document.getElementById(‘output’).textContent = JSON.XMP;’

The following code snippet shows how to add array items in XMP metadata in an EPS file in JavaScript:

  var fXMPAddArrayItem = function (e) {
    const file_reader = new FileReader();
    file_reader.onload = (event) => {
      const input = [
        ["dc:title", "NewTitle"],
        ["dc:creator", "NewCreator"]
      ];
      const JSON = XMPAddArrayItem(event.target.result, e.target.files[0].name, e.target.files[0].name + "_out.eps", input);
      if (JSON.errorCode == 0) {
          DownloadFile(JSON.fileNameResult, "image/eps");
      }
      else 
        document.getElementById('output').textContent = JSON.errorText;
    }
    file_reader.readAsArrayBuffer(e.target.files[0]);
  }
