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 <C_CkXmp.h>
#include <C_CkXml.h>

void ChilkatSample(void)
    {
    BOOL success;
    HCkXmp xmp;
    HCkXml xml;

    success = FALSE;

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

    xmp = CkXmp_Create();

    // 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 = CkXmp_NewXmp(xmp);

    // Add some properties...
    success = CkXmp_AddSimpleStr(xmp,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 = CkXml_SaveXml(xml,"newXmp.xml");
    if (success != TRUE) {
        printf("%s\n",CkXml_lastErrorText(xml));
        CkXmp_Dispose(xmp);
        return;
    }

    // To add the XMP to the JPG (or TIFF), simply load the JPG,
    // append the XMP, and save:
    success = CkXmp_LoadAppFile(xmp,"scream.jpg");
    if (success != TRUE) {
        printf("%s\n",CkXmp_lastErrorText(xmp));
