)К настоящему времени эта функция еще не была документирована; для ознакомления доступен только список аргументов.
Draws a quadratic Bezier curve from the current point to (x,y) using (x1,y1) as the control point using absolute coordinates. At the end of the command, the new current point becomes the final (x,y) coordinate pair used in the polybezier.
Список параметров
-
x1 -
x coordinate of the control point
-
y1 -
y coordinate of the control point
-
x -
x coordinate of the end point
-
y -
y coordinate of the end point
