| Method Summary | |
| abstract public void | cubicTo(int x1, int y1, int x2, int y2, int x3, int y3)
Draws a cubic Bezier curve starting at the current drawing
position and ending at the point (x3, y3)
according to the formulas:
x(t) = (1 - t)^3*x0 + 3*(1 - t)^2*t*x1 + 3*(1 - t)*t^2*x2 + t^3*x3
y(t) = (1 - t)^3*y0 + 3*(1 - t)^2*t*y1 + 3*(1 - t)*t^2*y2 + t^3*x3
0 <= t <= 1
where (x0, y0) is the current drawing position. | | abstract public void | quadTo(int x1, int y1, int x2, int y2)
Draws a quadratic Bezier curve starting at the current drawing
position and ending at the point (x2, y2)
according to the formulas:
x(t) = (1 - t)^2*x0 + 2*(1 - t)*t*x1 + t^2*x2
y(t) = (1 - t)^2*y0 + 2*(1 - t)*t*y1 + t^2*x2
0 <= t <= 1
where (x0, y0) is the current drawing position. |
| cubicTo | | abstract public void cubicTo(int x1, int y1, int x2, int y2, int x3, int y3)(Code) | | Draws a cubic Bezier curve starting at the current drawing
position and ending at the point (x3, y3)
according to the formulas:
x(t) = (1 - t)^3*x0 + 3*(1 - t)^2*t*x1 + 3*(1 - t)*t^2*x2 + t^3*x3
y(t) = (1 - t)^3*y0 + 3*(1 - t)^2*t*y1 + 3*(1 - t)*t^2*y2 + t^3*x3
0 <= t <= 1
where (x0, y0) is the current drawing position.
Finally, the current drawing position is set to (x3,
y3).
