The IDLgrContour::Init function method initializes the contour object.
Obj = OBJ_NEW('IDLgrContour' [, Values] [, PROPERTY=value])
Result = Obj->[IDLgrContour::]Init([Values] [, PROPERTY=value]) (Only in a subclass' Init method.)
When this method is called indirectly, as part of the call to the OBJ_NEW function, the return value is an object reference to the newly-created object.
When called directly within a subclass Init method, the return value is 1 if initialization was successful, or zero otherwise.
A vector or two-dimensional array of values to be contoured. If no values are provided, the values will be derived from the GEOMZ keyword value (if set and the PLANAR keyword is not set). In this case, the values to be contoured will match the Z coordinates of the provided geometry. IDL converts and maintains this data as double-precision floating-point if the argument is of type DOUBLE or if the DOUBLE_DATA keyword is set. Otherwise, the data is stored in single-precision. IDL returns the data as double-precision if it was stored in double-precision.
Any property listed under IDLgrContour Properties that contains the word "Yes" in the "Init" column of the properties table can be initialized during object creation using this method. To initialize the value of a property, specify the property name as a keyword set equal to the appropriate property value.
All other keywords are passed to the superclass of this object.
