Cairo.CurveTo (gb.cairo)
Static Sub CurveTo ( X1 As Float, Y1 As Float, X2 As Float, Y2 As Float, X3 As Float, Y3 As Float )
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).
-
X1 : the X coordinate of the first control point.
-
Y1 : the Y coordinate of the first control point.
-
X2 : the X coordinate of the second control point.
-
Y2 : the Y coordinate of the second control point.
-
X3 : the X coordinate of the end of the curve.
-
Y3 : the Y coordinate of the end of the curve.
If there is no current point before the call to Cairo.CurveTo this function will behave as if preceded by a call to Cairo.MoveTo(X1, Y1).
