curve To
Adds a cubic Bézier spline to the path from the current point to position (x3, y3) in user-space coordinates, using (x1, y1) and (x2, y2) as the control points. After this call the current point will be (x3, y3). If there is no current point before the call to curveTo then this function will behave as if preceded by a call to moveTo(cr , x1 , y1).
Parameters
The X coordinate of the first control point.
The Y coordinate of the first control point.
The X coordinate of the second control point.
The Y coordinate of the second control point.
the X coordinate of the end of the curve.
the Y coordinate of the end of the curve.
Parameters
The X coordinate of the first control point.
The Y coordinate of the first control point.
The X coordinate of the second control point.
The Y coordinate of the second control point.
the X coordinate of the end of the curve.
the Y coordinate of the end of the curve.
Parameters
The X coordinate of the first control point.
The Y coordinate of the first control point.
The X coordinate of the second control point.
The Y coordinate of the second control point.
the X coordinate of the end of the curve.
the Y coordinate of the end of the curve.
