Drawing Modes
You can choose one or both of the following Drawing Modes:
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 provides a device-
independent way for applications to gain access to the hardware
features of specific display devices. If you enable DirectDraw, your
application will have the choice of using DirectDraw or GDI. If you
disable DirectDraw, your application will use GDI instead of
DirectDraw. Please note that in any case, your application can always
use BarcoMed driver functions (i.e. WinBarco) or other graphics
extensions (such as OpenGL).
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. Adjacent pixels are assigned differing
color values; when viewed from a distance, these colors seem to
blend into a single intermediate color. The technique is similar to the
half-toning used in black-and-white publications to achieve shades of
gray. Please note that this option is only available when the User
Modifiable Palette Mode is selected. This is because dithering is only
supported under Windows when the display is palletized. 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 regardless of whether this check box is
checked. This complies with the Windows standard interface method.
Monitor Configuration
This option allows you to select the number of monitors that the
current display boards should drive, as well as how the monitors
should be positioned. For example, if the current board installation is
capable of driving four heads, but you only have three monitors which
are placed in a single row, then you can select the Three monitors
