What are you talking about?<br>
The frontend xsane is able to save an image with rgb and alpha channel.<br>
That was named SANE_FRAME_RGBI and this is not correct like you<br>
say too.<br>
All I did was to rename this function in xsane to SANE_FRAME_RGBA<br>
and I suggested to add this frame format to the sane standard.<br>
<p>
If a backend wants to save some image data as RGBA it only needs to<br>
say the image comes in fromat SANE_FRAME_RGBA.<br>
<p>
Here you write you want it back, in the other mail you write you do not<br>
want to have it saved as RGBA.<br>
Do you know what you want?<br>
<p>
<p>

<i>&gt; am now the proud owner of some random bytes. The contents are totally</i><br>

<p>
If you do not know what you scanned there is no one and nothing that can help<br>
you<br>
in that point. If you know what you scanned give the file a name that describes<br>
what<br>
you scanned!<br>
If you want to make it visible, the backend has to say in which color<br>
or you have to write a converting program that makes visible data from it.<br>
<p>
Bye<br>
