$y): bool
Оваа функција моментално не е документирана; достапна е само листата со аргументи.
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.
Параметри
x1-
x coordinate of the control point
y1-
y coordinate of the control point
x_end-
x coordinate of the end point
y-
y coordinate of the end point
