Creator Series 3 Options

The following options apply only to the Creator Series 3 Graphics Accelerator.

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 Creator and Creator 3D products. 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:

   ffbconfig -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:

   ffbconfig -gfile filename

Choosing Extended Overlay (-extovl)

Enabling the extended overlay option will switch the Series 3 Creator 3D from the standard overlay mode supported on series 1 or 2 to the new extended overlay functionality supported on Series 3. The extended overlay mode enables full 256-color overlays and hardware-accelerated Server Overlay Visuals. The maximum number of underlay Window IDs (WIDs) is increased from 32 to 64 and three new overlay WIDs are provided. Extended Overlays can only be enabled on DBZ boards running in a standard resolution.

To Configure for Extended Overlay Mode

1. Enter the following:

   ffbconfig -extovl enable
