Extracting IPTC data using QMeta is pretty much the same as extracting EXIF data as in my previous post – Using QMeta to extract Exif data in your Qt applications. So, here I only give you a simple example to extract object name and keywords from a picture.

#include <QtGui>
#include "qmeta/image.h"

int main (int argc, char *argv[])
{
  // Opens an image file. Currently supports only JPEG and TIFF files.
  qmeta::Image image("path/to/image");
  // Checks if the specified image is valid.
  if (image.IsValid()) {
    // Checks if IPTC data exists in this image.
    if (image.iptc()) {
      // Reads the object name from IPTC.
      qDebug() << image.iptc()->Value(qmeta::Iptc::kObjectName);
      // Reads keywords, note that I use the "Values()" function 
      // here because the "keywords" field is repeatable in IPTC.
      qDebug() << image.iptc()->Values(qmeta::Iptc::kKeywords);
    }
  }
  return 0;
}

As usual, you can find the full list of supported IPTC tags in its header file, just check the `enum Tag` type, and that’s all.
