Detailed Description

Object that describes a key frame for use in an IMovie.

Member Function Documentation

virtual signed int IMovieMakerKeyFrame::AskInterface ( const BGUID *  piid, IRoot **  ppr  )

pure virtual

Queries this object to see if the interface piid is supported and returns the result in ppr.

Parameters

piid	The BGUID of the requested interface.
ppr	The address of an IRoot pointer which will receive the new interface.

Returns

S_OK if the interface is supported. E_FAIL if it is not.

Implements IRoot.

virtual signed int IMovieMakerKeyFrame::Create ( RENDER_PARAMS *  parms, double  segmentLength, ENUM_MMKF_INTERPOLATION_TYPES  interpType  )

pure virtual

Helper function for initializing this object with the specified parameters.

Parameters

parms	The RENDER_PARAMS to store in this object.
segmentLength	The number of seconds between this key frame and the next one in the movie.
interpType	The interpolation type to use when craeting frames between this key frame and the next one in the movie.

virtual signed int IMovieMakerKeyFrame::CreateEx ( RENDER_PARAMS *  parms1, RENDER_PARAMS *  parms2, ENUM_WINDOW_TYPES  windowType, double  segmentLength, ENUM_MMKF_INTERPOLATION_TYPES  interpType  )

pure virtual

Reserved for future use.

virtual signed int IMovieMakerKeyFrame::DecRef ( )

pure virtual

Decreases the reference count on this object by 1. If the reference count reaches 0, the object is deallocated.

Implements IRoot.

virtual signed int IMovieMakerKeyFrame::GetParams ( BLEND_PARAMS **  parms )

pure virtual

Returns the address of the parameters that describe this key frame into the pointer at address parms. This is a shallow pointer and should not be deallocated by the caller.

Parameters

parms

The address of the BLEND_PARAMS pointer that will get the address of the internal params for this object.

virtual signed int IMovieMakerKeyFrame::IncRef ( )

pure virtual

Increases the reference count on this object by 1. You do not need to call this after an object is first created. It is 1 by default.

Implements IRoot.

virtual signed int IMovieMakerKeyFrame::SetParams ( BLEND_PARAMS &  parms )

pure virtual

Sets the BLEND_PARAMS for this object to parms.

Parameters

parms

The params to set for this object.
