Palette Mode
In the Palette Mode section you can choose one of the four following
Palette Modes. If you are using a color display in conjunction with your
Barco grayscale display(s), prior to selecting a palette mode please
make certain that you have configured your Windows desktop correctly.
(See the section
“Configuring the Windows desktop”
.)
Color to Gray Compatibility: Use this palette option for applications,
such as Java, which require True Color support. Such applications
may not work correctly when using one of Barco's three “Standard
8-bit (256-color)” palette modes. All applications that are
designed to work correctly with 8-bit (256-color) modes should
continue to work normally.
Note:
Dithering is
not
used while in this mode. Also, direct
access to the hardware through DirectDraw is
not
allowed in this
mode.
User Modifiable Color Palette: This option allows applications to
modify the palette contents dynamically. This mode reserves the
first 10 and last 10 entries in the palette for the Windows
operating system, but applications can manipulate the middle 236
entries. This is the standard palette mode as configured by
Windows.
Static Gray Palette including standard system colors: This option sets
the palette to be a static linear set of 236 gray values. The 20
standard system colors are converted from RGB to gray values and
are added to the 236 static gray values. Applications are denied
the ability to dynamically change or allocate palette entries.
Static Gray Palette with NO system colors: This option sets the palette
to be a static linear ramp of 256 shades of gray. Applications are
denied the ability to dynamically change or allocate palette
entries.
Please refer to the on-line help for more information on using
advanced features such as the different palette modes available.
