This is a response from a technical person at Microtek. Hopefully this info<br>
|
||
is useful for Bernd. The names were changed to protect the innocent. ;-)<br>

|

<i>>One problem XXXX said everyone runs into is in how to read the >color data</i><br>
|
||
that comes back from the scanner. Each line of data that >comes back is<br>
|
||
preceded by a letter R, G, or B. That first letter tells you >what channel<br>
|
||
the line is for. The scanner does NOT send back one >line of R, one line of<br>
|
||
G, one line of B, etc. The scanner sends back like >20 to 40 lines of red,<br>
|
||
20 to 40 lines of G, etc. So you have to check >and buffer each line that<br>
|
||
comes back.<br>

that info. But it seems unlikely that OnSpec would pass out >that info.<br>
|

Apparently, in order to talk to the chip, you either have to >have OnSpec<br>
|

develop the driver/backend for you, or you need the >whole source code for<br>

how they do it on the PC. In explaining how >they do the communications,<br>
|

they would be giving away their "trade >secrets" and helping their<br>

competitors. So you're right; it would be >easier to get OnSpec to write a<br>
