This is the interface for the LEAD Video Rotation Transform.
| Type | Name | Description |
|---|---|---|
| VARIANT_BOOL | Reverse | Sets or gets reverse option, set to TRUE to enable the reverse option. |
| VARIANT_BOOL | Flip | Sets or gets Flip option, set to TRUE to enable the flip option. |
| long | RotationAngle | Sets or gets the rotation angle, it should be a multiple of right angle (90). Unit of angle is degree. |
| VARIANT_BOOL | DefaultReverse | Default Reverse status.Original value is FALSE. |
| VARIANT_BOOL | DefaultFlip | Default Flip status.Original value is FALSE. |
| long | DefaultRotationAngle | Default Rotation Angle.Original value is zero. |
| long | InWidth | Read only; the input stream width. |
| long | InHeight | Read only; the input stream height. |
| long | OutWidth | Read only; the output stream width. |
| long | OutHeight | Read only; the output stream height. |
| long | InBits | Read only; the input stream bits per pixel. |
| long | OutBits | Read only; the output stream bits per pixel. |
None.
Reset the rotation option values to the default values.
None.
Loads transform settings from the registry. The Media Foundation transforms import the settings from the registry only at creation time. This method will force the transform to re-load its settings from the registry. If the transform has no settings to load from the registry, E_NOTIMPL is returned.
Return
S_OK if successful, S_FALSE otherwise.
None.
Writes transform settings to the registry. This method will force the transform to save its settings to the registry before its released.
If the transform has no settings to write to the registry, E_NOTIMPL is returned.
Return
S_OK if successful, S_FALSE otherwise.
Note:
Changes that affect the video frame dimensions cannot be performed while the media session is active, as a result these changes will be reverted. You must close the currently open media, change the properties, and then re-open the media.
