WMT_VIDEOIMAGE_TRANSITION_FLIP

  • Article

[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The flip transition rotates the old image on a y-axis through the center of the frame. The new image is revealed as the back of the old image.

Parameters

The following table describes the parameters used by this transition and lists the members of the WMT_VIDEOIMAGE_SAMPLE2 structure to which they are assigned.

Parameter Structure member Description
Angle fEffectPara0 Angle of the rotation, from 0.0 to 180.0 degrees.
Composition fEffectPara1 Set to one of the following values:
  • 0 - Specifies normal composition, in which the previous image is the background, and the current image is the foreground.
  • 1 - Specifies reversed composition, in which the current image is the background image, and the previous image is the foreground

Remarks

You can visualize the effect of this transition as if both images were physical photographs glued together back-to-back. The transition has the same effect as holding two such photographs at the center of the bottom edge and rotating them 180 degrees.
