|VARIANT_BOOL||Enabled||Enables or disables the effect. If set to VARIANT_FALSE, the filter will pass the video samples intact.|
|long||LightAngle||Controls the light angle on a horizontal plane (360 degree). Range: 0 to 360.|
|long||Elevation||Controls the light angle on a vertical plane (90 degree). Range: 0 to 90.|
|long||Depth||Controls the depth of the object, which will affect the shadow. 0 creates no shadow; higher values create deeper shadows. Range: 1 to 65.|
|long||XOffset||Horizontal offset of the resulting frames. Negative values shift to the left; positive values shift to the right. Range: -(Width-1) to Width-1, where Width is the video width.|
|long||YOffset||Vertical offset of the resulting frames. Negative values shift down; positive values shift up. Range: -(Height-1) to Height-1, where Height is the video height.|
|long||Ambient||Controls the relative strength of a directional light. This property is used to control the shadow intensity. A higher value results in less shadow. Range: 0 to 255.|
|VARIANT_BOOL||UseBuffer||Flag that indicates which buffer to use. Possible values are:|
|• VARIANT_TRUE - Use the buffer set in the SetMapBuffer method.|
|• VARIANT_FALSE - Use the source video buffer.|
|If this property is VARIANT_TRUE but no buffer has been set using the SetMapBuffer method, the source video buffer is used.|
|VARIANT_BOOL||Invert||Flag that indicates whether to invert shadow and light in the movie. Possible values are:|
|• VARIANT_TRUE - Invert shadow and light.|
|• VARIANT_FALSE - Do not invert shadow and light.|
|VARIANT_BOOL||EffectAreaEnabled||Enables or disables the effect for a cropped video area. Area limits are set using the Left, Top, Right and Bottom properties.|
|long||Left||Left boundary of the effect area.|
|long||Top||Top boundary of the effect area.|
|long||Right||Right boundary of the effect area.|
|long||Bottom||Bottom boundary of the effect area.|
Sets an unaligned buffer to be used in the bump effect.
Pointer to a map buffer.
