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. Unicode C++

#include <CkXmpW.h>
#include <CkXmlW.h>

void ChilkatSample(void)
    {
    bool success = false;

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

    CkXmpW xmp;

    CkXmlW *xml = 0;

    // 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,L"Iptc4xmpCore:Chilkat",L"Blah blah");
    // If you wish to view the XML, save it to a file and review it
    // with a text editor:
    success = xml->SaveXml(L"newXmp.xml");
    if (success != true) {
        wprintf(L"%s\n",xml->lastErrorText());
        return;
    }

    // To add the XMP to the JPG (or TIFF), simply load the JPG,
    // append the XMP, and save:
    success = xmp.LoadAppFile(L"scream.jpg");
    if (success != true) {
        wprintf(L"%s\n",xmp.lastErrorText());
        return;
