Well, I should read the documentation more clearly before making statements<br>
|
|||
|
|
like this. There is a case where the depth does "sort of" imply a data<br>
|
|||
|
|
transmission format from a depth value. In the case where the depth == 1<br>
|
|||
|
|
with value data (ie Lineart scans) SANE declares that this should be a<br>
|
|||
|
|
packed data format with 8 pixels per byte. This exception makes a lot of<br>
|
|||
|
|
sense (it seems to be the natural trasmission format for Lineart scans)<br>
|
|||
|
|
but it *is* an exception. So the general rule still stands.<br>
