poIImagePlane GetSyncBlockID

Gets the unique animation sync block for the image plane.

Syntax

Imageplane_handle GetSyncBlockID

Application

HyperView Tcl Query

Description

Unique animation sync block IDs are used by HyperView to identify each source of animated frames. Though not directly visible to the end user, sync block IDs are used by the “Time Scales” panel to synchronize multiple windows or videos. This command returns the unique sync block ID associated with the image plane.

Example

To create two image planes, and then query it for basic properties and settings:
