Although the nonlinear static gray palette provides correct
colors for applications using the Windows palette, colors
display incorrectly if the application assumes that a static
palette is always ramped.
To run DOME calibration software with the nonlinear static
gray palette, use Calibration TQA 2.0.3 or later.
Applications cannot set the nonlinear static gray palette.
They must read the palette from the operating system and
use it when drawing directly to the framebuffer. Application
colors display incorrectly if the application assumes all 8-bit
framebuffers have palettes that can be set.
Static gray palette
The static gray palette provides 256 shades of gray in a static
palette. This palette does not reserve the first and last 10 palette
entries for icons and other standard Windows graphics, which
frees the entire grayscale ramp for applications.
The static gray palette does not provide gray-mapped Windows
colors for the first and last 10 palette entries. Because the frame-
buffer assumes the Windows palette is in use, applications that
draw directly to the framebuffer display incorrectly. For exam-
ple, icons and button bitmaps may display in black and white.
To run DOME calibration software with the static gray palette,
use Calibration TQA 2.0.3 or later.
Applications cannot set the static gray palette. They must
read the palette from the operating system and use it when
drawing directly to the framebuffer. Application colors display
