If you do a linear tranformation this is simply a multiplication and so<br>
|
||
the lower 4 bits are not used.<br>
|
||
<p>
|
||
And that this is done as a linear tranfromation should be clear!<br>
|
||
<p>
|
||
So: IT IS THE CASE DESCRIBED ABOVE!<br>

It is not right that the software is "mugging their precious pixel values"<br>
