Interface Methods:

HRESULT IsLEADInputPinConnected()

Parameters

None.

Description

Determines whether the filter input pin is currently connected.

Returns

S_OK if connected, S_FALSE otherwise.

HRESULT IsLEADOutputPinConnected()

Parameters

None.

Description

Determines whether the filter output pin is currently connected.

Returns

S_OK if connected, S_FALSE otherwise.

HRESULT SetMosaicAttributes(MOSAIC_ATTRIBUTES mosaic_attributes)

Parameters

mosaic_attributes

a MOSIAC_ATTRIBUTES structure that contains the mosaic attributes to set.

Description

Sets the properties for the mosaic effect.

Returns

S_OK if successful, S_FALSE otherwise.

HRESULT GetMosaicAttributes(MOSAIC_ATTRIBUTES *mosaic_attributes)

Parameters

mosaic_attributes

a valid pointer to a MOSIAC_ATTRIBUTES structure to be updated with the current mosaic attributes.

Description

Retrieves the current mosaic attributes.

Returns

S_OK if successful, S_FALSE otherwise.

HRESULT SetCropAttributes(CROP_ATTRIBUTES crop_attributes)

Parameters

crop_attributes

a CROP_ATTRIBUTES structure that contains the effect area attributes to set.

Description

Sets the effect area attributes. If successful, effect is applied only to the passed rectangle.

Returns

S_OK if successful, S_FALSE otherwise.

HRESULT GetCropAttributes(CROP_ATTRIBUTES *crop_attributes)

Parameters

crop_attributes

a valid pointer to a CROP_ATTRIBUTES structure to be updated with the current effect area attributes.

Description

Retrieves the current effect area attributes.

Returns

S_OK if successful, S_FALSE otherwise.

HRESULT GetIODimensions(long *plInWidth, long *plInHeight, long *plOutWidth, long *plOutHeight)

Parameters

plInWidth

A valid pointer to a long variable to be updated with the input media width. NULL can be passed if this value is not needed.

plInHeight

A valid pointer to a long variable to be updated with the input media height. NULL can be passed if this value is not needed.

plOutWidth

A valid pointer to a long variable to be updated with the output media width. NULL can be passed if this value is not needed.

plOutHeight

A valid pointer to a long variable to be updated with the output media height. NULL can be passed if this value is not needed.

Description

Retrieves the current media dimensions.

Returns

S_OK if successful, S_FALSE otherwise.

HRESULT GetIOBitCount(int *pInBitCount, int *pOutBitCount)

Parameters

pInBitCount

A valid pointer to an integer to be updated with the input media bits per pixel value. NULL can be passed if this value is not needed.

pPBitCount

A valid pointer to an integer to be updated with the output media bits per pixel value. NULL can be passed if this value is not needed.

Description

Gets the bits per pixel of the current connected input and output media formats.

Returns

S_OK if successful, S_FALSE otherwise.
