Hi Andreas,<br>
|
|
<p>
|
|
that is the reason why I renamed it!<br>
|
|
The frontend does not need to know how the alpha channel<br>
|
|
is generated, so it is better to name it alpha than infrared.<br>
|
|
<p>
|
|
I sent some changes of sane.tex to David as suggestion<br>
|
|
at that point!<br>
|
|

|
|
Bye<br>
