Remarks

This event notification is sent whenever a video renderer detects a change in native video size.

An application might use this notification to negotiate space in a compound document.

The actual video dimensions are available through the IBasicVideo control interface.

The DirectShow renderers detect whether the video has changed size prior to sending these events.
