The LIVE_RECT procedure is an interface for insertion of rectangles.
LIVE_RECT [, COLOR='color name' ] [, /DIALOG] [, DIMENSIONS=[width, height]] [, ERROR=variable] [, /HIDE] [, LINESTYLE={0 | 1 | 2 | 3 | 4 | 5}] [, LOCATION=[x, y]] [, NAME=string] [, /NO_DRAW] [, /NO_SELECTION] [, REFERENCE_OUT=variable] [, THICK=pixels{1 to 10}] [, VISUALIZATION_IN=string] [, WINDOW_IN=string]
None
Set this keyword to a string (case-sensitive) of the color to be used for the rectangle. The default is `Black'. The following colors are available:
Set this keyword to have the rectangle dialog appear. This dialog will fill in known attributes from set keywords.
Set this keyword to a two-element, floating-point vector of the form [width, height] to specify the dimensions of the rectangle in normalized coordinates. The default is [0.2, 0.2].
Set this keyword to a named variable to contain the returned error message (string). An empty string is returned if no errors occurred during the operation. By default, errors are reported via a GUI.
| Note If a named variable is passed in this keyword and an error occurs, the error GUI will not be displayed. |
Set this keyword to a boolean value indicating whether this item should be hidden.
Set this keyword to a pre-defined line style integer:
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 [0.5, 0.5].
| Note LOCATION may be adjusted to take into account window decorations. |
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 to a variable to return a structure defining the names of the modified items. The fields of the structure are shown in the following table.

Set this keyword to an integer value between 1 and 10, specifying the line thickness to be used to draw the line, in pixels. The default is one pixel.
Set this keyword equal to the name (string, case-insensitive) of a LIVE tool visualization. The VIS field from the REFERENCE_OUT keyword from the creation of the LIVE tool will provide the visualization name. 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 window or a LIVE tool buffer. The WIN 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 window (or buffer) is present in the IDL session, this keyword will default to it.
