Change array items in XMP metadata of EPS| Java

In order to change array items in XMP metadata of EPS file it is necessary to do several steps:

1. Initialize an input stream for input EPS file.
2. Create an instance of PsDocument from created earlier input stream.
3. Get an instance of XmpMetadata from the PsDocument. If given EPS file doesn’t contain XMP metadata the new one will be created, filled in with values from PS metadata comments and returned to you.
4. Now you can change items of array metadata fileds.
5. Initialize an output stream for output EPS file.
6. Save EPS file with changed XMP metadata.

Following code snippet shows how to change array items in XMP metadata in EPS file in Java:

// For complete examples and data files, please go to https://github.com/aspose-page/Aspose.Page-for-Java
// Set license
new License().setLicense(BaseExamplesTest.LICENSE_PATH);

// The path to the documents directory.
String dataDir = Utils.getDataDir();

// Initialize input EPS file stream
FileInputStream psStream = new FileInputStream(dataDir + "xmp3.eps");

PsDocument document = new PsDocument(psStream);

try {
    // Get XMP metadata. If EPS file doesn't contain XMP metadata we get new one filled with values from PS metadata comments (%%Creator, %%CreateDate, %%Title etc)
    XmpMetadata xmp = document.getXmpMetadata();

    // Set "dc:title" array item by index 0 
    xmp.setArrayItem("dc:title", 0, new XmpValue("NewTitle"));
    
    // Set "dc:creator" array item by index 0
    xmp.setArrayItem("dc:creator", 0, new XmpValue("NewCreator"));
    
    
    // Initialize output EPS file stream
    FileOutputStream outPsStream = new FileOutputStream(dataDir + "xmp3_changed.eps");
    
    // Save document with changed XMP metadata
		try {			
			document.save(outPsStream);
		} finally {
			outPsStream.close();
		}

} finally {
    // close input EPS stream
		psStream.close();
}
