Well, you make a very convincing argument, and you do have this hardware<br>
|
||
sat in front of you, which I don't. I asked this before, but I can't<br>
|
||
remember what exactly you said in response:<br>
|
||
<p>
|
||
Does it make sense to you (considering the TWAIN way of doing it among<br>
|
||
other things) for us to provide the results of a stuff like barcode<br>
|
||
scans in a SANE Option (just like you can specify the R/G/B exposures<br>
|
||
used by an auto-calibrating slide scanner) OR more like the existing<br>
|
||
image transfer frames, only with text in?<br>
|
||
<p>
|
||
Initially I thought that using SANE Options was a nicer way, because you<br>
|
||
can have something like this (I might be bending SANE's rules here a<br>
|
||
little bit, but I think it works today, in theory)<br>
|
||
<p>
|
||
SANE Option "Barcodes", hardware feature, not user alterable, string<br>
|
||
constraint { "9 780201 835953", "3 057640 136993", "MULTIM-44-2731" }<br>
|
||
<p>
|
||
But if this stuff is just another output from a scan which might also<br>
|
||
give us 5 JPEGs and a couple of G32D images, then I guess the text<br>
|
||
frame makes a lot of sense. Formatting it would be your problem :)<br>
