Get XMP metadata from EPS file using Java

In order to extract XMP metadata from 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.

Following code snippet shows how to extract XMP metadata from 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 + "xmp1.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 a width of a thumbnail image if exists
    if (xmp.containsKey("xmp:Thumbnails") && xmp.get("xmp:Thumbnails").isArray()) {
        XmpValue val = xmp.get("xmp:Thumbnails").toArray()[0];
        if (val.isNamedValues() && val.toNamedValues().containsKey("xmpGImg:width"))
            System.out.println("Thumbnail Width: " + val.toNamedValues().get("xmpGImg:width").toInteger());
    }

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

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

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