CurveTo Class

classCurveTo : Segment

Namespace:datalogics_interface

Inherits from:: Segment

Detailed Description

The curved segment is appended to a path.

The curveto operator calculates the curve between two endpoints, the current (beginning) point and the final (end) point, and in relation to two matching control points.

The control points define the nature of the curve between the two endpoints. These values are represented by a series of x and y coordinates.

Point

Constructor & Destructor Documentation

CurveTo(const Point &p1, const Point &p2, const Point &p3)

Parameters

p1: const Point &: the first control point.
p2: const Point &: the second control point.
p3: const Point &: the new current point.

Append a cubic Bézier curve to the current path. The curve extends from the current point to point3, using point1 and point2 as the Bézier control points. The new current point is point3.

CurveTo(doublex1, doubley1, doublex2, doubley2, doublex3, doubley3)

Parameters

x1: double: the first control point.
y1: double: the second control point.
x2: double: the new current point.
y2: double
x3: double
y3: double

Append a cubic Bézier curve to the current path. The curve extends from the current point to point3, using point1 and point2 as the Bézier control points. The new current point is point3.
