Parameters
graphics
[in] Pointer to the
Graphics
object.
pen
[in] Pointer to a pen that is used to
draw the Bezier splines.
points
[in] Pointer
to an array of PointF structures that specify the
coordinates that the cardinal spline passes through.
count
[in] Long integer value that
specifies the number of elements in the points
array.
offset
[in] Long integer value
that specifies the element in the points array that
specifies the point at which the cardinal spline begins.
numberOfSegments
[in] Integer
that specifies the number of segments in the cardinal spline.
tension
[in] Single precision value that specifies how
tightly the curve bends though the coordinates of the cardinal spline.
Remarks
A segment is defined as a curve that connects
two consecutive points in the cardinal spline. The ending point of each
segment is the starting point for the next. The numberOfSegments
parameter must not be greater than the count
parameter minus the offset parameter plus one.
