CGContextAddQuadCurveToPoint

CGContextAddQuadCurveToPoint is a function in the Core Graphics framework of Apple's operating systems, used for drawing quadratic Bézier curves. It is part of the Quartz 2D drawing API. This function adds a quadratic Bézier curve to the current path of a graphics context. A quadratic Bézier curve is defined by three points: a starting point, a single control point, and an ending point. The starting point of the curve is the current point of the path. The function takes the graphics context, the x and y coordinates of the control point, and the x and y coordinates of the ending point as arguments. The control point influences the curvature of the line, pulling it towards itself. The curve is drawn from the current point to the specified end point, with the specified control point dictating the shape of the curve. After the curve is added, the end point of the curve becomes the new current point of the path. This function is fundamental for creating smooth, curved shapes in Core Graphics-based applications, such as user interfaces, graphics editors, and vector drawing tools.
