示例1: copyMetadata
void ExifTransfer::copyMetadata() {
try {
dst = Exiv2::ImageFactory::open(BasicIo::AutoPtr(new MemIo(data, dataSize)));
dst->readMetadata();
} catch (Exiv2::Error & e) {
std::cerr << "Exiv2 error: " << e.what() << std::endl;
return;
}
try {
src = Exiv2::ImageFactory::open(srcFile.toLocal8Bit().constData());
src->readMetadata();
copyXMP();
copyIPTC();
copyEXIF();
} catch (Exiv2::Error & e) {
std::cerr << "Exiv2 error: " << e.what() << std::endl;
// At least we have to set the SubImage1 file type to Primary Image
dst->exifData()["Exif.SubImage1.NewSubfileType"] = 0;
}
try {
dst->writeMetadata();
FileIo fileIo(dstFile.toLocal8Bit().constData());

fileIo.write(dst->io());
fileIo.close();
} catch (Exiv2::Error & e) {
std::cerr << "Exiv2 error: " << e.what() << std::endl;
}
