The LIVE_RECT procedure is an interface for insertion of rectangles.
Set this keyword to a string (case-sensitive) of the color to be used for the rectangle. The color must be specified as an Insight color. The default is `Black'. Available colors are listed in the table below.
Set this keyword to a two-element, floating-point vector of the form [X, Y] specifying the location of the visualization (relative to the lower left hand corner within the visualization window) in normalized coordinates. The default is [0.0, 0.0].
Set this keyword equal to a string containing the name to be associated with this item. The name must be unique within the given window or buffer (WINDOW_IN). If not specified, a unique name will be assigned automatically.
Set this keyword to inhibit the visualization window from drawing. This is useful if multiple visualizations and/or annotations are being created via calls to other LIVE_Tools in order to reduce unwanted draws and help speed the display.
Set this keyword equal to the name (string, case-insensitive) of a LIVE tool or Insight visualization. The VISUALIZATION field from the REFERENCE_OUT keyword from the creation of the LIVE tool will provide the visualization name. Visualization names are also visible in Insight's Visualization Manager and visualization property dialogs. If only one visualization is present in the window or buffer (WINDOW_IN), this keyword will default to it.
Set this keyword equal to a name (string, case-sensitive) of a LIVE tool or Insight window, or a LIVE tool buffer. The WINDOW tag of the REFERENCE_OUT structure from the creation of the LIVE tool will provide the window or buffer name. Window names are also visible in visualization window titlebars. If only one LIVE tool or Insight window (or buffer) is present in the IDL session, this keyword will default to it.
