6 | Board Architecture
The 10-bit DAC on the DOME boards can produce up to 1024
distinct analog values. Thus, the board can perform gamma
correction and send 256 distinct pixel values to the display,
to produce a truer, more accurate grayscale image.
The flat-panel method is somewhat different but still allows
more than 256 display value. The interface to the flat-panel
driver is the same as that for the traditional display boards.
Accessing the gamma correction tables
You can access the gamma correction tables (GCTs) in both
Windows
GCTs in Windows
If you are running a Windows operating system, use the
dynamic link library (DLL) provided with the DOME Windows
driver to set the GCT. For more information, see "DSetGCT" on
page 47.
The Windows operating system uses 8-bit color. Once you set
the GCT, the DOME Windows driver translates all palette
changes to the 10-bit value.
GCTs in Solaris
If you are running a Solaris operating system, initialize the
GCT to a linear ramp and load it into the hardware with the
InitGCT
programming interface).
