Class HEmulatedGraphicsConfiguration

public class HEmulatedGraphicsConfiguration
extends HGraphicsConfiguration

An HEmulatedGraphicsConfiguration is a configuration for a "virtual" graphics device that may perform one or more emulations, e.g. in the ATSC context an HEmulatedGraphicsDevice might implement multiple HEmulatedGraphicsConfigurations, corresponding to each of the possible relationships to the high-definition display modes. The HEmulatedGraphicsConfiguration would be used to configure a device appropriately for rendering into, whilst mapping the emulated device onto the "true" physical display, e.g. by down-sampling to standard-definition display.

In essence the HEmulatedGraphicsConfiguration may be considered as a pair of HGraphicsConfiguration objects: one describing the configuration of the emulation and the second describing the corresponding configuration of the implementation.

Hence, an HGraphicsConfiguration may be considered as a special case of the HEmulatedGraphicsConfiguration class, where the emulation and implementation are equivalent.

The parameters to the constructors are as follows, in cases where parameters are not used, then the constructor should use the default values.

Default parameter values exposed in the constructors

Parameter	Description	Default value	Set method	Get method
None.

Default parameter values not exposed in the constructors
