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. |
