Hi,
I currently want to implement that CreationDate and ModDate are set during
the file embedding, because the ModDate is required by the PDF/A-3
specifications.
My idea is to implement it by following.
#############
# PdfInputStream.cpp //Method declarations and include needs to be done in
PdfInputStream.h
#############
#include "base\PdfDate.h"
PdfDate PdfFileInputStream::GetModifiedDate()
{
struct stat file_stat;
int fp = fileno(m_hFile);
fstat(fp, &file_stat);
return PdfDate(file_stat.st_mtime);
}
PdfDate PdfFileInputStream::GetCreationDate()
{
struct stat file_stat;
int fp = fileno(m_hFile);
fstat(fp, &file_stat);
return PdfDate(file_stat.st_ctime);
}
#############
# PdfFileSpec.cpp
#############
void PdfFileSpec::EmbeddFile( PdfObject* pStream, const wchar_t*
pszFilename ) const
{
PdfFileInputStream stream( pszFilename );
pStream->GetStream()->Set( &stream );
// Add additional information about the embedded file to the stream
PdfDictionary params;
params.AddKey( "Size", static_cast<pdf_int64>(stream.GetFileLength())
);
PdfString mod_date;
stream.GetModifiedDate().ToString(mod_date);
params.AddKey("ModDate", mod_date);
PdfString creation_date;
stream.GetCreationDate().ToString(creation_date);
params.AddKey("CreationDate", creation_date);
pStream->GetDictionary().AddKey("Params", params );
}
void PdfFileSpec::EmbeddFile( PdfObject* pStream, const char* pszFilename
) const
{
PdfFileInputStream stream( pszFilename );
pStream->GetStream()->Set( &stream );
// Add additional information about the embedded file to the stream
PdfDictionary params;
params.AddKey( "Size", static_cast<pdf_int64>(stream.GetFileLength())
);
PdfString mod_date;
stream.GetModifiedDate().ToString(mod_date);
params.AddKey( "ModDate", mod_date);
PdfString creation_date;
stream.GetCreationDate().ToString(creation_date);
params.AddKey( "CreationDate", creation_date );
pStream->GetDictionary().AddKey("Params", params );
}
Are there some things if forgot or could be done better?
If not will someone implement it or should I create a patch file for that?
