- The _m_c_o_g_a_m_m_a 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.
-
- OOOOPPPPTTTTIIIIOOOONNNNSSSS
- ----pppp ppppiiiippppeeee####
- Specify which graphics pipe number to use. In a machine with a
- single graphics pipe, this must be set to zero.
-
- ----cccc cccchhhhaaaannnnnnnneeeellll####
- Specify which channel of the MCO to change; this must be a value
- from zero to five.
-
- ----ffff ffffiiiilllleeeennnnaaaammmmeeee
- 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.
-
- HHHHAAAARRRRDDDDWWWWAAAARRRREEEE
- _m_c_o_g_a_m_m_a works only on IRIS RealityEngine, RealityEngine2, and VTX
- graphics equipped with the optional MultiChannel Option (MCO) hardware.

-
- NOTES
- 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.
