<p>

the sane standard defines of how much frames an image consists.<br>
|
|||
|
|
After the last frame - that means if the image is transferred completly -<br>
|
|||
|
|
the frontend has to call sane_cancel.<br>
|
|||
|
|
<p>
|
|||
|
|
We should not changes this behaviour!!!<br>
|
|||
|
|
<p>
|
|||
|
|
But when we define the sane-standard version 2 we can add new function calls,<br>
|
|||
|
|
so we could add a call like sane_start_next() that tells the backend to transmit<br>
|
|||
|
|
<p>
|
|||
|
|
the next image of the scan that is done.<br>
|
|||
|
|
<p>
|
|||
|
|
Your frontend (scanadf) and your backend do not work like described in<br>
|
|||
|
|
the sane standard in the moment.<br>
|
|||
|
|
<p>
|
|||
|
|
Please do not try to change the recent standard in a way that everthing else<br>
|
|||
|
|
has to be changed. We should make a new standard that is as compatible as<br>
|
|||
|
|
possible to the existing one!<br>
|
|||
