bool MWAWOLEParser::isOle10Native ( MWAWInputStreamPtr  ip,
std::string const &  oleName 
) [static, protected]

theOle10Native : basic Windows© picture, with no size

Referenced by parse(), and readOle10Native().

bool MWAWOLEParser::isOlePres ( MWAWInputStreamPtr  ip,
std::string const &  oleName 
) [static, protected]

the OlePres001 seems to contain standart picture file and size

Referenced by parse(), and readOlePres().

tries to parse basic OLE (excepted mainName)

Returns:
false if fileInput is not an Ole file

first check if this is a mac pict as other oles may not be understand by openOffice, ...

bool MWAWOLEParser::readCompObj ( MWAWInputStreamPtr  ip,
std::string const &  oleName,

the CONTENTS : seems to store a header size, the header and then a object in EMF (with the same header)...

Note:
I only find such lib in 2 files, so the parsing may be incomplete and many such Ole rejected
