Hello,

I am generating a RTF file from Python 2.1 with Zope 2.4, using the =
"Rich Text Format (RTF) Version 1.6 Specification" =
(http://msdn.microsoft.com/library/specs/rtfspec.htm).

But I can not include a "jpg" image in the RTF file. For including the =
"jpg" image file, firstly, I have obtainted the hexadecimal =
representation of the image with Image.encode("hex") from PIL library:

Import Image
img =3D Image.open("photo.jpg")
file =3D open("filename","wb")
file.write(img.encode("hex"))
file.close()

However, this hexadecimal representation is no good, because when, for =
example, I save the same image with Microsoft Word in RTF format, these =
representations no match.

Anybody can help me ?

Thank you very much.
