Hmm... the sample color QuickCam image on the SANE page looks<br>
|
|
OK, but it doesn't seem as if the B&W version is doing the scaling.<br>
|
|
I'm willing to fix the problem and submit a patch if someone can tell<br>
|
|
me where the scaling code should go. Would it simply be a matter of<br>
|
|
adding a scaling loop just before the following code in<br>
|
|
reader_process()? <br>
|
|
<p>
|
|
/* now write the whole thing to the main process: */<br>
|
|
if (fwrite (src, 1, num_bytes, ofp) != num_bytes)<br>
|
|
...<br>
