<P>In your experience, do the fast hardware scanners ever leave anything

"out-of-band" which a user might need in order to reconstruct the image

but which isn't included in the stream, such as image dimensions or

<BR>
|

color type /depth info ?

|

<P>You said JFIF in your example, does that mean that the data coming out
|
|
<BR>
|
|
of the scanners is a true JFIF compliant file, or just that it would

|
<BR>
|

be easy in the frontend or backend to prepend the appropriate APPn

markers and data?
