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 SetEmbossAttributes( EMBOSS_ATTRIBUTES emboss_attributes)

Parameters

emboss_attributes

an EMBOSS_ATTRIBUTES structure that contains emboss attributes to set.

Description

Sets the properties for the emboss effect.

Returns

S_OK if successful, S_FALSE otherwise.

HRESULT GetEmbossAttributes(EMBOSS_ATTRIBUTES *emboss_attributes)

Parameters

emboss_attributes

a valid pointer to an EMBOSS_ATTRIBUTES structure to be updated with the current emboss attributes.

Description

Retrieves the current emboss 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.

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
