Extract and Edit Text From EMF Spool file?
Hi, I have an .emf spool file and I want to extract the data (text, images etc).
But how?
I know I have to use EMR_EXTTEXTOUTW or EMR_EXTTEXTOUTA, but I don't know how to use it..
Any help?

I am trying to extract unicode text from the EMF files extracted from the printed SPL (spool file).
I can't find any description or source code that describes exactly how to read the following EMF records.
EmfExtTextOutA
EmfExtTextOutW
EmfSmallTextOut

I created a program that reads an emf file and gets the text with this code:
int CALLBACK EnhMetaFileProc (HDC hdc, HANDLETABLE * pHandleTable,
CONST ENHMETARECORD * pEmfRecord, int iHandles, LPARAM pData)
{
ENHMETARECORD * pEmfr;
pEmfr = (ENHMETARECORD *) malloc (pEmfRecord->nSize);
CopyMemory (pEmfr, pEmfRecord, pEmfRecord->nSize);
if(pEmfr->iType==EMR_EXTTEXTOUTW)
{
PEMREXTTEXTOUTW pExtTextOutW = (PEMREXTTEXTOUTW)pEmfr;
MessageBox(NULL,(LPWSTR)((BYTE *)pEmfr +
pExtTextOutW->emrtext.offString),TEXT("text"),0);
}
PlayEnhMetaFileRecord (hdc, pHandleTable, pEmfr, iHandles) ;
free (pEmfr) ;
return TRUE ;
}
The text is : (LPWSTR)((BYTE *)pEmfr + pExtTextOutW->emrtext.offString)
The problem is that if(pExtTextOutW->emrtext.fOptions==ETO_GLYPH_INDEX)
I get some stranges characters , not the text.
Can someone help me to get the right characters?
Thank You.
