IMcStreamReadFrames Method

This method allows the client to read an array of frames from a sequence, and place them in particular frames of an existing image. For example, the client may wish to read frames 6,10, and 12 of a sequence file, and place them in Frame locations 3,9,and 11 of the image, respectively. The two SAFEARRAY's are matched descriptor to descriptor, for example, the first array member of the stream_range array will be placed into the first array member of the image_range.
