I'm sorry Paulo, but I don't get it, in JAI I'm encoding an image so that I
get a jpeg encoded format, RTF accepts jpgs so it should be happy with it.
The only way to add this to an RTF document is by creating a
com.lowagie.text.Image, which I do by using static Image's getInstance()
method. Why a jpeg encoded image is not recognized as such when going
through and output stream which is not a FileOuputStream? I know I might be
lacking some basic knowledge here, but thanks for your help.
