Serach text within a metafile.

[MF]

Do someone knows how to search for text in a WMF/EMF canvas ?
(EnumEnhMetaFile & EnhMetaFileProc ?)

I would like to know the text but the position and font too.
Can anyone point me in the right direction ?

Best regards,

[Daniel Rüdisser]

Dear MF,
I'm not sure if I have understood your problem, but:
EMF, and WMF consist of (32-bit (EMF) or
16-bit (WMF) records of the following type:

ReferenceNo,Size,[Data]

Size contains the length of the whole record (counted
in 32-bit (EMF) or 16-bit integers). (So data
has the length size-2 !)
So it is easy to scramble through the file and
read the records.
When you find a record with a reference number
used by a TextOut command (eg. 83,84) then you
can go through the data of this record.
The format of the records (structures) is given
in the MSDN library:
http://msdn.microsoft.com/library/en-us/gdi/metafile_5hkj.asp?frame=true
So it shouldn't be a problem to find your text and
the font type.
Kind Regards,
Don Dan

See EnumEnhMetaFile & EnhMetaFileProc in the online help. Takes a
callback which gets passed each record in the metafile. /johan
