ILMVBumpMap Interface

Interface Properties:

Type	Name	Description
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.

Interface Methods:

HRESULT SetMapBuffer (BYTE *pBuffer, long lWidth, long lHeight)

Parameters

pBuffer	pointer to a map buffer.
lWidth	width of the map.
lHeight:	height of the map.

Description

Sets an unaligned buffer to be used in the bump effect.

Return

S_OK if connected, S_FALSE otherwise.
