ILMVHologram Interface

Data types:

This filter has no specific data types, but includes the following enumeration for use with its programming interface:

enum REFERENCE_FRAME 
{ 
   REF_USEBUFFER, 
   REF_USENEXTFRAME, 
   REF_USECOLOR, 
};

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	Hue	Value used to change the color of the effect. Hue is a color wheel (360 degree). Range: 0 to 360.
VARIANT_BOOL	LineNoise	Show/hide a noise line. If this property is VARIANT_TRUE, the noise line appears as it is moving from the bottom to the top.
long	Noise	Gets or sets the noise density. Range: 1 to 100.
VARIANT_BOOL	FirstFrameIsReference	Enables or disables setting the first frame in every play session as the reference frame. If this is VARIANT_TRUE, the first frame in every play session will be set as the reference frame (Usually the first frame in a movie). If this property is VARIANT_FALSE, then the reference frame should be set manually after a number of frames. Setting this property after the stream starts will have no effect.
long	Threshold	Value used to control an object's detection level. A lower threshold provides stronger object detection. Range : 1 to 100.
VARIANT_BOOL	NoReferenceFrame	Flag that controls the reference frame. If this property is VARIANT_TRUE, the reference frame is assumed to be a black buffer. If it is VARIANT_FALSE, the reference frame will be the frame set by the user through theSetReferenceFrame method or by setting the FirstFrameAsReference property.

pBuffer	buffer contains the reference frame. This buffer should have the same dimensions (width and height), and the same bits per pixel as the movie.
lRGBColor	pixel color (RGB 24-bit). The reference frame will be set as a solid frame with the color specified in this parameter.
opt	flag that controls the reference frame. Possible values are:
	Value	Meaning
	REF_USEBUFFER	only the pBuffer member is used.
	REF_USENEXTFRAME	the next frame in the movie is taken as the reference frame.
	REF_USECOLOR	the lRGBColor parameter is used.

Sets the reference frame of the movie.

Return

S_OK if connected, S_FALSE otherwise.
