Constructor and Destructor


o CAT2DLineRep
public CAT2DLineRep()
Default constructor.
o CAT2DLineRep
public CAT2DLineRep( const iPoints)
Constructs the representation of a 2D segment.
Parameters:
iPoints
The coordinates of the extremities of the 2D segment (XYXY).
o CAT2DLineRep
public CAT2DLineRep( const iPoints,
const iNbPoints,
const iAlloc=ALLOCATE,
const iLinetype= LINES,
const iTessFlag= LINE)
Constructs a 2D line representation from point coordinates.
Parameters:
iPoints
Array of point coordinates: XYXYXY... Its size is equal to two times the number of points.
iNbPoints
The number of points.
iAlloc
Flag used to specify whether points must be duplicated or not.
Legal values:
  • ALLOCATE : All data are duplicate into the graphic primitive
  • DONT_ALLOCATE The graphic primitive has a pointer to the data given as parameter
The default value is ALLOCATE.
iLineType
Flag to specify the line type to use.
Legal values:
  • LINES : The number of points must be even. A line will be drawn between points 1 and 2, another line will be drawn between points 3 and 4, ... 
                           point 1 X--------------------X point 2
                                                   point 3 X-----------------------X point 4
  • LINE_STRIP : The number of points can be either even or odd. A line will be drawn between points 1 and 2, then, another line will be drawn between points 2 and 3, ... 
                           point 1 X--------------------X point 2
                                                   /
                                                 /

                                      point 3 X----------------------X point 4
  • LINE_LOOP : Same as LINE_LOOP, excepted that one more line will be drawn between the last and the first points. 
                                        point 1 X--------X point 2
                                             \      /
                                              \    /

                                      point 3 X----X point 4
The default value is LINES.
