Function Reference


_GDIPlus_PathAddBezier

Adds a bezier spline to the current figure of a path

#include <GDIPlus.au3>
_GDIPlus_PathAddBezier ( $hPath, $nX1, $nY1, $nX2, $nY2, $nX3, $nY3, $nX4, $nY4 )

Parameters

$hPath Pointer to a GraphicsPath object
$nX1 X coordinate of the starting point
$nY1 Y coordinate of the starting point
$nX2 X coordinate of the first control point
$nY2 Y coordinate of the first control point
$nX3 X coordinate of the second control point
$nY3 Y coordinate of the second control point
$nX4 X coordinate of the ending point
$nY4 Y coordinate of the ending point

Return Value

Success: True.
Failure: False and sets the @error flag to non-zero, @extended may contain GPSTATUS error code ($GPID_ERR*).

Remarks

A Bezier spline does not pass through its control points. The control points act as magnets, pulling the curve in certain directions to influence the way the spline bends.
