Add XMP metadata to EPS file using Java

In order to add XMP metadata to 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 view values of metadata fileds.
5. Initialize an output stream for output EPS file.
6. Save EPS file with new XMP metadata.

Following code snippet shows how to add XMP metadata to 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 + "xmp2.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();

    // Get "CreatorTool" value
    if (xmp.containsKey("xmp:CreatorTool"))
        System.out.println("CreatorTool: " + xmp.get("xmp:CreatorTool").toStringValue());
    
    // Get "CreateDate" value
    if (xmp.containsKey("xmp:CreateDate"))
        System.out.println("CreateDate: " + xmp.get("xmp:CreateDate").toStringValue());

    // Get "Title" value
    if (xmp.containsKey("dc:title"))
        System.out.println("Title: " + xmp.get("dc:title").toArray()[0].toStringValue());

    // Get "format" value
    if (xmp.containsKey("dc:format"))
        System.out.println("Format: " + xmp.get("dc:format").toStringValue());

    // Get "creator" value
    if (xmp.containsKey("dc:creator"))
        System.out.println("Creator: " + xmp.get("dc:creator").toArray()[0].toStringValue());
    
    // Get "MetadataDate" value
    if (xmp.containsKey("xmp:MetadataDate"))
        System.out.println("MetadataDate: " + xmp.get("xmp:MetadataDate").toStringValue());
    
    
    // Initialize output EPS file stream
    FileOutputStream outPsStream = new FileOutputStream(dataDir + "xmp2_changed.eps");
    
    // Save document with new XMP metadata
		try {			
			document.save(outPsStream);
		} finally {
			outPsStream.close();
		}

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