In XMP SDK 5.2.
in function PhotoDataUtils::ExportExif
it asks ISOSpeedRatings to be an array item, but it is not. Any special consideration to make it this way? Thanks.
haveXMP = xmp->DoesPropertyExist ( kXMP_NS_EXIF, "ISOSpeedRatings" );
if ( haveXMP ) {
XMP_Index i, count;
std::string isoValue;
bool haveHighISO = false;
for ( i = 1, count = xmp->CountArrayItems ( kXMP_NS_EXIF, "ISOSpeedRatings" ); i <= count; ++i ) {
xmp->GetArrayItem ( kXMP_NS_EXIF, "ISOSpeedRatings", i, &isoValue, 0 );
if ( SXMPUtils::ConvertToInt ( isoValue.c_str() ) > 0xFFFF ) { haveHighISO = true; break; }
}
if ( ! haveHighISO ) {
haveExif = exif->GetTag ( kTIFF_ExifIFD, kTIFF_ISOSpeedRatings, 0 );
if ( ! haveExif ) { // ISOSpeedRatings has an inject-only mapping.
ExportArrayTIFF ( exif, kTIFF_ExifIFD, kISOSpeedMapping, exif->IsNativeEndian(), *xmp, kXMP_NS_EXIF, "ISOSpeedRatings" );
}
xmp->DeleteProperty ( kXMP_NS_EXIF, "ISOSpeedRatings");
}
}
