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. C++

#include <CkXmp.h>
#include <CkXml.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.

    CkXmp xmp;

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

    //  To add the XMP to the JPG (or TIFF), simply load the JPG,
    //  append the XMP, and save:
    success = xmp.LoadAppFile("scream.jpg");
    if (success != true) {
        std::cout << xmp.lastErrorText() << "\r\n";
        return;
    }

    success = xmp.Append(*xml);
    if (success != true) {
        std::cout << xmp.lastErrorText() << "\r\n";
        return;
    }

    success = xmp.SaveAppFile("screamOut.jpg");
    if (success != true) {
        std::cout << xmp.lastErrorText() << "\r\n";
        return;
    }
    }
