Setting Gamma Correction (-g, -gfile)

Gamma correction may be set by specifying a gamma correction value or by specifying a file that contains a gamma table.

The -g option will set the gamma table entries based on the gamma value specified. A gamma value of 2.22 represents linear gamma correction and matches the fixed value on the Expert3D system. This value is a per-screen value and therefore all gamma corrected or linear visuals will use this value.

To Set the Gamma Correction Using a Value

1. Enter the following:

   SUNWifb_config -g 2.22

The -gfile option will set the gamma table entries explicitly from a file containing three columns of 256 integers ranging from 0 to 255. The format is three integers separated by a newline character. Each line contains the RGB value to be put in the table for that entry. This value is a per-screen value and therefore all gamma-corrected or linear visuals will use this value.

To Set the Gamma Correction Using a File

1. Enter the following:

   SUNWifb_config -gfile filename
