Please note that dithering is not permitted while in this mode. The

Enable Dithering check box will be grayed-out, and dithering will be

automatically disabled regardless of whether this check box is checked.

This complies with the Windows standard interface method. If you are

unsure whether or not your application requires this “Static Gray Palette

including Standard System Colors” mode, contact your application

provider.

Static Gray Palette with NO system colors

This option sets the palette to be a static linear ramp of 256 shades of

gray. Therefore, applications are denied the ability to dynamically

change or allocate palette entries. This prevents palette conflicts

between applications, which can cause image color values to appear

distorted in the background application.

As shown in figure 31, each of the 256 entries in the palette has an RGB

value of (i, i, i) where i is the index from 0 to 255.

Figure 32

If you wish to use a static gray palette we recommend using the “Static

Gray Palette including Standard System Colors” option instead of this

one. This is due to the fact that some applications assume that the first

and last 10 entries of the palette are the standard system colors. In this

palette mode, these entries are made up from entries in the bottom or

the top of the gray ramp. Please note that dithering is not permitted
