-
-    // This is the quickest way to add (simple) Exif data. If a metadatum for

*************************************************************************
-    // Modify Exif data
-
-    // Since we know that the metadatum exists (or we don't mind creating a new

-              << "\", new value \"" << tag.value() << "\"\n";
-
-    // Alternatively, we can use findKey()
-    key = Exiv2::ExifKey("Exif.Image.PrimaryChromaticities");
-    Exiv2::ExifData::iterator pos = exifData.findKey(key);
-    if (pos == exifData.end()) throw Exiv2::Error(1, "Key not found");
-    // Get a pointer to a copy of the value
-    v = pos->getValue();
-    // Downcast the Value pointer to its actual type
-    Exiv2::URationalValue* prv = 
dynamic_cast<Exiv2::URationalValue*>(v.release());
-    if (prv == 0) throw Exiv2::Error(1, "Downcast failed");
-    rv = Exiv2::URationalValue::AutoPtr(prv);
-    // Modify the value directly through the interface of URationalValue
-    rv->value_[2] = std::make_pair(88,77);
-    // Copy the modified value back to the metadatum
-    pos->setValue(rv.get());
-    std::cout << "Modified key \"" << key 
-              << "\", new value \"" << pos->value() << "\"\n";
-
-    // 
*************************************************************************
-    // Delete metadata from the Exif data container
-
-    // Delete the metadatum at iterator position pos
-    key = Exiv2::ExifKey("Exif.Image.PrimaryChromaticities");
-    pos = exifData.findKey(key);
-    if (pos == exifData.end()) throw Exiv2::Error(1, "Key not found");
-    exifData.erase(pos);
-    std::cout << "Deleted key \"" << key << "\"\n";

-    // 
*************************************************************************
-    // Finally, write the remaining Exif data to the image file
