This reminds me. Some of the scanners I'm working on not only generate<br>
|
|
compressed images, but can have multiple images per page. I'm thinking<br>
|
|
for example of one document scanner that can, for each page, produce<br>
|
|
all at once:<br>
|
|
<p>
|
|
up to 8 color images<br>
|
|
up to 8 gray images<br>
|
|
up to 8 binary images<br>
|
|
<p>
|
|
Not to mention backside images as well. Each image can have different<br>
|
|
characteristics (i.e. JFIF color/gray, TIFF G4 binary) and dimensions.<br>
|
|
In particular, the scanner supports windows with these different properties<br>
|
|
and their own scan area. An aware application needs to be able to find<br>
|
|
out that these images are from the same page. Ideas?<br>
|
|
<p>
|
|
This is not so pressing to me as the application being able to select<br>
|
|
compressed frame formats (and blocking formats it can't handle) but<br>
|
|
someone should be thinking of these things.<br>
|
|
<p>
|
|
I know, I'm a pest on this list:-)<br>
