Syntax
FUNCTION GdipAddPathBezierI (BYVAL path AS GpPath PTR, BYVAL x1 AS INT_, BYVAL y1 AS INT_, BYVAL x2 AS INT_, BYVAL y2 AS INT_, BYVAL x4 AS INT_, BYVAL y3 AS INT_, BYVAL x4 AS INT_, BYVAL y4 AS INT_) AS GpStatus
GdipAddPathBezier — one description covers them all.Parameters
| Name | Description | |
|---|---|---|
path | [in] Pointer to the GraphicsPath object. | |
x1 | [in] The x-coordinate of the starting point of the Bézier spline. | |
y1 | [in] The y-coordinate of the starting point of the Bézier spline. | |
x2 | [in] The x-coordinate of the first control point of the Bézier spline. | |
y2 | [in] The y-coordinate of the first control point of the Bézier spline. | |
x3 | [in] The x-coordinate of the second control point of the Bézier spline. | |
y3 | [in] The y-coordinate of the second control point of the Bézier spline. | |
x4 | [in] The x-coordinate of the ending point of the Bézier spline. | |
y4 | [in] The y-coordinate of the ending point of the Bézier spline. |
Description
Adds a Bézier spline to the current figure of this path.
