The image transmitted with radio frequencies is different (how exactly?) to that transmitted optically, the image transmitted optically being the decoded text, with the coded image being derived from the message. Now there's a thought (I've just used the word 'message' instead of character). Markus is talking about varying the image for each usage of a character: On Mon, 03 Mar 2003 14:32:28 +0000 Markus Kuhn <[EMAIL PROTECTED]> wrote: > The X11 font system is in addition at present not capable to vary each > useage of a glyph, as it would be essential to make sure the filtering > does not actually leak more information on digital video links. Why not vary character usage by varying the transmitted image of a word (phrase, paragraph, entire message) as a whole. Might be easier to do and more effective than attempting to vary the usage of individual characters. Not sure if you could do this with Freetype2. Then again adding more to the coded message (radio frequency image) other than recoding an individual character might not be necessary.
