Exiv2

Please attach a sample image so I can investigate your file. I'll use the commands $ exiv2 -pS yourImageFile and $ exiv2 -pR yourImageFile to look into your file.

Exiv2 supports Exif, IPTC, XMP and ICC metadata embedded in many image formats including JPG, PNG, Tiff and numerous others. Without knowing more about your format, I can't say anything about the effort involved to support your format. That exiftool supports your format is encouraging. Exiv2 is open-source and you are welcome to write the necessary code and submit it for review and integration with Exiv2. If you are asking us to write the code, the marketing people would ask the question "What is the business case for supporting your format?". We have a back-log of formats waiting for Engineering resources.

I am hosting a meeting of Team Exiv2 at my home in England on May 5 & 6. Additional image formats are on the agenda for discussion. http://dev.exiv2.org/news/3

Great exiv2 -pR works.

Sorry I can't share the data as it belongs to my company.

Another question, when I am trying to code the same thing, I also don't see the "new" metadata. Let's say I have a tag called "ISOSpeedRatings" for example, how could I display it in my code ? I tried the example supplied on the website but it doesn't display it :

Exiv2::Image::AutoPtr image1 = Exiv2::ImageFactory::open(filename1);
      assert(image1.get() != 0);

image1->readMetadata();
    Exiv2::ExifData &exifData = image1->exifData();

if (exifData.empty()) {
        std::string error(filename1);
        error += ": No Exif data found in the file";
        throw Exiv2::Error(1, error);
    }

Exiv2::ExifData::const_iterator end = exifData.end();
    for (Exiv2::ExifData::const_iterator i = exifData.begin(); i != end; ++i) {
        const char* tn = i->typeName();
        std::cout
                  << std::dec << i->value()
                  << "\n";
    }
