CGPathAddQuadCurveToPoint
Appends a quadratic Bézier curve to a mutable graphics path.
Declaration
extern void CGPathAddQuadCurveToPoint(CGMutablePathRef path, const CGAffineTransform *m, CGFloat cpx, CGFloat cpy, CGFloat x, CGFloat y);Parameters
- path:
The mutable path to change. The path must not be empty.
- m:
A pointer to an affine transformation matrix, or
NULLif no transformation is needed. If specified, Core Graphics applies the transformation to the curve before adding it to the path. - cpx:
The x-coordinate of the control point.
- cpy:
The y-coordinate of the control point.
- x:
The x-coordinate of the end point of the curve.
- y:
The y-coordinate of the end point of the curve.
Discussion
Before returning, this function updates the current point to the specified location (x, y).
