ILMVHologram Interface

Data Types

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

REFERENCE_FRAME

Summary

Specifies the reference frame.

Syntax

enum REFERENCE_FRAME 
{ 
   REF_USEBUFFER, 
   REF_USENEXTFRAME, 
   REF_USECOLOR, 
}; 

Members

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.

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 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. Possible values are:
• VARIANT_TRUE - the first frame in every play session will be set as the reference frame (Usually the first frame in a movie).
• 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. Possible values are:
• VARIANT_TRUE - the reference frame is assumed to be a black buffer.
• VARIANT_FALSE - the reference frame will be the frame set by the user through theSetReferenceFrame method or by setting the FirstFrameAsReference property.

Methods

HRESULT SetReferenceFrame (byte *pBuffer, long lRGBColor, REFERENCE_FRAME opt)

Description

Sets the reference frame of the movie.

Parameters

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.

Returns

Return Description
S_OK Connected.
S_FALSE Otherwise.
