???
|
||
|
Receives 4 bytes of data
|

|
VENDOR-9
|
||
|
Get calibration lines - 12 lines
|

|
0x00 color scan
|
||
|
0x01 grayscal scan
|
||
|
0x02 b&w scan
|
||
|
Returns 6 bytes per pixel, probably 2 bytes per color in little endian order. (2550 * 6 = 15300)
|
||
|
|
||
|
VENDOR-0C
|
||
|
??? Unsupported?
|
||
|
|
||
|
|
||
|
VENDOR-0E
|
||
|
Set calibration. Apparently the line is computed from the calibration lines. It is not an average though.
