IDxtKey Interface

The IDxtKey interface sets properties on the Key transition.

This interface is used internally by DirectShow Editing Services (DES) when it renders the Key transition. DES applications do not need to use this interface. To set the properties on a transition in DES, use the IPropertySetter interface.

In addition to the methods inherited from IDXEffect, the IDxtKey interface exposes the following methods.

Method Description
get_Hue Retrieves the hue value on which to key.
get_Invert Retrieves a Boolean value indicating whether the key operation is inverted.
get_KeyType Retrieves the type of key.
get_Luminance Retrieves the luminance value on which to key.
get_RGB Retrieves the RGB color on which to key.
get_Similarity Retrieves the range of color data that becomes transparent.
put_Hue Specifies the hue value on which to key.
put_Invert Specifies whether the key operation is inverted.
put_KeyType Specifies the type of key.
put_Luminance Specifies the luminance value on which to key.
put_RGB Specifies the RGB color on which to key.
put_Similarity Specifies the range of color data that becomes transparent.
