Hi!
When reading XMP data from files, the toolkit sometimes fails to open the file and I am not quite sure how to approach the problem. My method:
QStringXmpParser::getXmpContent(QStringfilePath)
{try{
SXMPMeta::Initialize();
SXMPFiles::Initialize();
XMP_VersionInfocoreVersion;
SXMPMeta::GetVersionInfo(&coreVersion);
std::stringxmpContent;
XMP_OptionBitsopts=kXMPFiles_OpenForRead|kXMPFiles_OpenUsePacketScanning;
XMP_StringPtrfilenamePtr=(XMP_StringPtr)filePath.toUtf8();
SXMPFilesmyfile;
if(!myfile.Initialize(opts)){
qDebug()<<"FailedtoinitializeSXMPFile.";
}
if(!myfile.OpenFile(filenamePtr,kXMP_UnknownFile,opts)){
qDebug()<<"FailedtoopenSXMPFilefor"<<filePath;
}
if(!myfile.GetXMP(NULL,&xmpContent)){
qDebug()<<"NoXMPdatainfile"<<filePath;
}
SXMPFiles::Terminate();
SXMPMeta::Terminate();
returnQString::fromUtf8(xmpContent.c_str());
}catch(XMP_Error&e){
qDebug()<<"Exception:"<<e.GetErrMsg();
return"";
}
}
I often get the output:
Failed to open SXMPFile for "(...)52x61.jpg"
Exception: XMPFiles::GetXMP - No open file
Oddly, rescanning the file may solve the problem - so I am not sure where there is a problem in the first place. Are there any alterations for the code I should try?
