Drawing Modes; Enable Directdraw; Enable Dithering; Monitor Configuration - Barco CORONIS 1MP System Manual

Drawing Modes

You may 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 –
one row" option from the pull-down list. This would cause the
Windows virtual desktop to be resized to fit on the three monitors,
and you can move your cursor horizontally from one screen to the
other.
