mcogamma(1G)mcogamma(1G)NAMEmcogamma - set gamma on MultiChannel Option channels
SYNOPSISmcogamma -p# -c# -f<filename>
DESCRIPTION
The mcogamma command allows the setting of the gamma lookup table
directly for each output of the MultiChannel Option. This command affects
the MultiChannel Option only, and has no effect on the standard graphics
output.
OPTIONS-p pipe#
Specify which graphics pipe number to use. In a machine with a
single graphics pipe, this must be set to zero.
-c channel#
Specify which channel of the MCO to change; this must be a value
from zero to five.
-f filename
Specify the file which describes the gamma table. This must be a
text file of 1024 lines; each line has three integers from 0 to
1023, in ASCII format, separated by white space. The three integers
represent the red, green, and blue output intensities respectively,
for this entry.
For instance, a file corresponding to a gamma of 1.0 would look like
this:
0 0 0
1 1 1
2 2 2
3 3 3
[... and so on ...]
1023 1023 1023
If the above file was saved to disk as gammaone, then the command
mcogamma-p0 -c2 gammaone
would set the gamma of the main graphics pipe, MCO output number 2,
to 1.0.
HARDWAREmcogamma works only on IRIS RealityEngine, RealityEngine2, and VTX
graphics equipped with the optional MultiChannel Option (MCO) hardware.

The normal gamma command, and the value in the file
/etc/config/system.glGammaVal, have no effect on the MCO output.
MCO gamma reverts to the default whenever graphics is initialized.
