ripole output stream offset

hello,
i've compiled ripmime under a windows cygwin environment.
ripmime works well (i've used it to export my mail from
an earthlink totalaccess2004 client by first composing a
message to which all eml files in a folder are attatched,
then saving the message to a file, then extracting).

i've also tried the included ripole support. i was only
able to output streams on a word2000 document using the
[--save-unknown-streams] switch, which output six streams,
the first of which closely resembles the jpg image inserted
using insert->picture->fromfile. the original picture has
71189 bytes, while the output stream has 71564 bytes. the
hexdumps below show the added bytes at the top of the ole
stream.

Hello there Moses,

Appologies about the slow response - I've been too busy building model airplanes (radio controlled :-)

Unfortunately at this point, ripMIME (or rather ripOLE) doesn't know how to handle embedded images, rather it can
currently only handle attached images/files. Attached files appear as a seperate file in the OLE struture complete with
filename headers and size representation, this is all documented in the OLE formats/standards.... however, embedded
images (and other embedded files) fall under the Microsoft Word (Office I guess) /structure/ format - that is something
beyond the immediate scope of ripOLE... not sure if I'm making any sense.

If anyone knows how to accurately determine how to name/format these streams, I'd love to know.

Regards.

I always thought (trying to use MS speak/usage) a packaged object (most
easily created by dragging and dropping a file into an ms office document)
is an entirely different mechanism to just inserting a graphic image. I
wouldn't think the latter has anything to do with OLE at all.

Generally, yes that is correct - at least that's also what I believe.

What I have noticed though is that sometimes it might depend on the setup of Office... too many variables.

In short, as you said, drag-and-drop'd items are not generally available to ripOLE (although they do appear as 'unknown
streams').
