</EM><BR>
|
|
<P> Stephen> Well, I think what scanner vendors in general want to do is
|
|
<BR>
|
|
Stephen> be able to write their own dialog box that the user can use
|
|
<BR>
|
|
Stephen> to configure the scanner in magical and scanner specific
|
|
<BR>
|
|
Stephen> ways. At the TWAIN level, that sort of thing does make
|
|
<BR>
|
|
Stephen> sense, I think. (At the SANE level, it does not as private
|
|
<BR>
|
|
Stephen> tags are the way to handle these. I imagine this scanner
|
|
<BR>
|
|
Stephen> specific dialog can use the standard SANE protocol to
|
|
<BR>
|
|
Stephen> communicate.)
|
|
<BR>
|
|
<P> Stephen> Of course, I'm coming from the perspective of a
|
|
<BR>
|
|
Stephen> high-performance scanner manufacturer where $0.05 worth of
|
|
<BR>
|
|
Stephen> labor won't kill us, but not having the desired convenient
|
|
<BR>
|
|
Stephen> access to Nifty Feature X really hurts.
|
|
<BR>
|
|
<P>In my mind, that's a separate issue. Yes, I do think that there may
|
|
<BR>
|
|
be a need to reserve a range of SANE_TYPE_* numbers for
|
|
<BR>
|
|
vendor-specific options. If we do this, I'd really like to see some
|
|
<BR>
|
|
sort of certification procedure to ensure that this mechanism doesn't
|
|
<BR>
|
|
get abused. Basically, the goal would be to ensure that the vendor
|
|
<BR>
|
|
specific options are used only when absolutely necessary and that the
|
|
<BR>
|
|
scanner always remains usable with the standard options.
|
|
<BR>
|
|
<P>Of course, a scanner vendor would want/need to provide a custom front
|
|
<BR>
|
|
end to be able to make use of these options. However, I think this is
|
|
<BR>
|
|
different from simply trying to write a fancy-looking custom frontend
|
|
<BR>
|
|
for the standard SANE options, so I think we should keep them
|
|
<BR>
|
|
separate. I.e., there are two issues here:
|
|
<BR>
|
|
<P> (i) how to customize the look of the scanner dialog
|
|
<BR>
|
|
<P> (ii) how to provide an "escape" or "pass-through" mechanism that
|
|
<BR>
|
|
permits for more extensibility (and how to do this without
|
|
<BR>
|
|
completely breaking interoperability)
