Hi Wolfgang,<br>
|
||
<p>
|
||
Sane does not use pipes for writing image-data, because three pass scanners send<br>
|
||
the image data in single colors. So scanimage/xsane needs to store at least two<br>
|
||
of the<br>
|
||
three colors and then merge it together. That makes a lot of problems with pipes<br>
|
||
beacuse<br>
|
||
you can not do a rewind on a pipe.<br>
|
||
<p>
|
||
If you use the photocopy mode of xsane, xsane writes the postscript file to<br>
|
||
stdout.<br>
|
||
You can enter any command that can handle pipes in printersetup, eg: "xv -"<br>
|
||
instead of "lpr -"<br>
|
||
<p>
|
||
I don`t see any advantage of writing a pnm file to stdout in a graphical user<br>
|
||
interface. You can use<br>
|
||
scanimage for it.<br>
|
||
<p>
|
||
Bye<br>
