Note from current maintainer:
-----------------------------

This is a rather old info sheet from Frank Lyonnet that probably doesn't
interest anyone now that Acorn has provided the JFIF decoding routines in
RO3.6. Anyway, I keep it here for historical reasons.

I think that FYEO's main interest is the pleasure people have to use it (it
can hold several document at once), not particularly its decoding speed. It
also has a better dithering than the routines in RO3.6 (try them on a 256
color mode).

This file contains the results of speed tests of two test images
on FYEO and its challengers :-) .

Note : I recall that ChangeFSI and SlideShow RiscPC app. use the same JPEG
code (provided in the ChangeFSI application).
