Function

CGPathAddLineToPoint

Appends a line segment to a mutable graphics path.

Declaration

void CGPathAddLineToPoint(CGMutablePathRef path, const CGAffineTransform *m, 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 NULL if no transformation is needed. If specified, Core Graphics applies the transformation to the line before it is added to the path.

x

The x-coordinate of the end point of the line.

y

The y-coordinate of the end point of the line.

Discussion

Before returning, this function updates the current point to the specified location (x,y).
