<i>&gt; ----------</i><br>
<i>&gt; Valid bit depths are 1, 8, or 16 bits per sample. If a device's</i><br>
<i>&gt; natural bit depth is something else, it is up to the driver to scale</i><br>
<i>&gt; the sample values appropriately (e.g., a 4 bit sample could be scaled</i><br>
<i>&gt; by a factor of four to represent a sample value of depth 8).</i><br>
<i>&gt; ----------</i><br>
<i>&gt; </i><br>
Maybe I'm just nitpicking or simply don't get it -<br>
but shouldn't this actually read:<br>
<p>
...a 4 bit sample could be scaled by a factor of _seventeen_...<br>
<p>
or maybe<br>
<p>
e.g., a 4 bit sample could be shifted left by 4 bit to represent a <br>
sample value of depth 8 or even better multiplied by a factor of<br>
0x11 (17) so that white pixels still map to white pixels (15*17=255)<br>
