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:
- Create file reader ‘const file_reader = new FileReader();’ and read file ‘file_reader.readAsArrayBuffer(e.target.files[0]);’.
- On load event handler call AsposeXMPAddArrayItem and pass the file content, his name, and the result file name to it.
- 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).
- The result JSON contains the file name in fileNameResult and gets metadata in the XMP element.
- 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:
1 var fXMPAddArrayItem = function (e) {
2 const file_reader = new FileReader();
3 file_reader.onload = (event) => {
4 const input = [
5 ["dc:title", "NewTitle"],
6 ["dc:creator", "NewCreator"]
7 ];
8 const JSON = XMPAddArrayItem(event.target.result, e.target.files[0].name, e.target.files[0].name + "_out.eps", input);
9 if (JSON.errorCode == 0) {
10 DownloadFile(JSON.fileNameResult, "image/eps");
11 }
12 else
13 document.getElementById('output').textContent = JSON.errorText;
14 }
15 file_reader.readAsArrayBuffer(e.target.files[0]);
16 }
