The bytesperline looks ok if you are doing a color scan of 637 pixels/line
|
||
<BR>
|
||
637*3 = 1911 bytes. There is one byte each for red/green/blue pixel data.
|
||
<BR>
|
||
I'm not sure what your other problem could be. Can you scan at any
|
||
<BR>
|
||
resolution successfully? How about greyscale scans?

Subject: The problem of xscanimage by CanoscanFB620S
|

<BR>
|
||
<P><P><EM>> Hi,
|
||
</EM><BR>
|
||
<EM>> I'm trying to work xscanimage by CanoscanFB620S properly.
|
||
</EM><BR>
|
||
<EM>> The problem of xscanimage by CanoscanFB620S is that
|
||
</EM><BR>
|
||
<EM>> the scanimage made by FB620S is not a normal image.
|
||
</EM><BR>
|
||
<EM>> The image is the diagonal stripes against black.
|
||
</EM><BR>
|
||
<EM>> I tried to look up the debug-file and I thought that the cause of
|
||
</EM><BR>
|
||
<EM>> the diagonal stripes scanimage was a difference between
|
||
</EM><BR>
|
||
<EM>> number of 'bytes_per_line' and number of bytes of
|
||
</EM><BR>
|
||
<EM>> 'sanei_scsi_req_wait'. I think the number of 'bytes_per_line' must be
|
||
</EM><BR>
|
||
equal
|
||
<BR>
|
||
<EM>> to the number of bytes of 'sanei_scsi_req_wait'.
|
||
</EM><BR>
|
||
<EM>> Is my thought wrong?
|
||
</EM><BR>
|
||
<EM>> Would anybody teach me the part of sane program which I change
|
||
</EM><BR>
|
||
<EM>> to fix the difference of 'bytes_per_line' and 'sanei_scsi_req_wait'
|
||
</EM><BR>
|
||
<EM>> if my thought is not wrong.
|
||
</EM><BR>
|
||
<EM>> Would anybody teach me the way of fix the difference.
|
||
</EM><BR>
|
||
<EM>>
|
