Drawing Modes
In the Drawing Mode section you can choose from the following
Drawing Modes. If any of the options in this section are grayed
out, then they are not available for the model controller with
which you are working.
Enable DirectDraw
This option allows the user to enable or disable DirectDraw.
DirectDraw is a software interface that provides direct access to
display devices while maintaining compatibility with the
Windows graphics device interface (GDI). DirectDraw is enabled
by default.
More information about DirectDraw is available through the on-
line help.
Enable Dithering
This option allows the user to enable or disable dithering.
Dithering is a technique for increasing the perceived range of
colors in an image at the cost of spatial resolution.
Note: This option is only available when the User Modifiable
Palette mode is selected. If either the Static Gray Palette
including Standard System Colors mode or the Static Gray Palette
with NO System colors mode is selected, the “Enable Dithering”
check box will be grayed-out, and dithering will be automatically
disabled.
