Add XMP MetaData to JPG or TIFF

See more XMP Examples

Demonstrates how to add XMP metadata to a JPG or TIFF image that doesn't already have XMP metadata. Swift

func chilkatTest() {
    var success: Bool = false

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    let xmp = CkoXmp()!

    var xml: CkoXml?

    // The first step is to create a new XMP document, which is nothing
    // more than XML.  The NewXmp method returns an XML document with
    // the standard XMP boilerplate.  
    xml = xmp.newXmp()

    // Add some properties...
    success = xmp.addSimpleStr(xml: xml, propName: "Iptc4xmpCore:Chilkat", propVal: "Blah blah")
    // If you wish to view the XML, save it to a file and review it
    // with a text editor:
    success = xml!.save(path: "newXmp.xml")
    if success != true {
        print("\(xml!.lastErrorText!)")
        return
    }

    // To add the XMP to the JPG (or TIFF), simply load the JPG,
    // append the XMP, and save:
    success = xmp.loadAppFile(path: "scream.jpg")
    if success != true {
        print("\(xmp.lastErrorText!)")
        return
    }

    success = xmp.append(xml: xml)
    if success != true {
        print("\(xmp.lastErrorText!)")
        return
    }

    success = xmp.saveAppFile(path: "screamOut.jpg")
    if success != true {
        print("\(xmp.lastErrorText!)")
        return
    }
