Add XML namespace in XMP metadata of EPS

To add an XML namespace in the XMP metadata of an 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 AsposeXMPAddNamespace and pass the file content, its name, result file name, prefix, url, and an array of key-value pairs for the new namespace to it.
3. The result JSON contains the file name in fileNameResult.
4. You can download files by using the DownloadFile function: ‘DownloadFile(JSON.fileNameResult, “image/pdf”);’ and display the result ‘document.getElementById(‘output’).textContent = JSON.XMP;’

following code snippet shows how to add an XML namespace in XMP metadata in an EPS file in C++:

  var fXMPAddNamespace = function (e) {
    const file_reader = new FileReader();
    file_reader.onload = (event) => {
      const prefix = "tmp";
      const url = "http://www.some.org/schema/tmp#";
      const input = [
        ["tmp:newKey", "NewValue"]
      ];
      const JSON = AsposeXMPAddNamespace(event.target.result, e.target.files[0].name, e.target.files[0].name + "_out.eps", prefix, url, input);
      if (JSON.errorCode == 0) {
          DownloadFile(JSON.fileNameResult, "image/eps");
      }
      else 
        document.getElementById('output').textContent = JSON.errorText;
    }
    file_reader.readAsArrayBuffer(e.target.files[0]);
  }
