<P>This is probably legal, the alternative would be for the backend to

<BR>
|

reset brx/ bry whenever tlx/ tly get too large. We could write an

implementation note for backend designers which recommends one way

|

or the other I suppose.

</EM><BR>
|
|
<P>Well, I would think that's probably best fixed in xsane/ xscanimage
|
|
<BR>
|
|
for now, a quick and easy solution is to set tlx, tly, then brx, bry
|
|
<BR>
|
|
and then tlx, tly again to be sure.
|
|
<BR>
|
|
<P>In fact, I think I've seen this problem, but I couldn't swear which

<BR>

|
backend I've seen the behaviour you describe on.

<P>[snipped]
|
|
<BR>
|
|
<EM>> The result is, that I have to choose the scan area twice (most of the time)
|

</EM><BR>
