ImageClip.GetImage
v2.0
Returns the Image data associated with
the clip.
Note: For performance considerations, try not only call this method
when the plug-in intends to read actual pixel values. For example,
you can determine the resolution more quickly via the Source object, as demonstrated in one of the
examples under the main ImageClip
topic.

oReturn = ImageClip.GetImage( [Variant] ); |

| Variant | Variant | Frame at which to retrieve the image. This is only meaningful
when the ImageClip represents an image sequence or movie file.
