Hi Mike,<br>
<p>
<i>&gt; There are several PC graphics cards and many UNIX workstations that</i><br>
<i>&gt; provide 32-48 bits per pixel. The current limit for X-based systems</i><br>
<i>&gt; is 32-bits per pixel.</i><br>
<p>
As far as I know the 32bit mod of the PC-graphic-cards is a<br>
mode where the 3 of 4 bytes are used for 24-bit-rgb and the<br>
4.th byte isn't used. It is easyer and faster to use 4 bytes per pixel<br>
instead of 3 bytes per pixel. It is not a mode where 32 bits are<br>
available for color-information.<br>
<p>
Bye<br>
Oliver<br>
