Question

I m looking for the equivalent function of sprite.graphics.curveTo() in ActionScript for PHP with Imagick. List of function which may do the trick :

bool pathCurveToAbsolute ( float $x1 , float $y1 , float $x2 , float $y2 , float $x , float $y )
bool pathCurveToQuadraticBezierAbsolute ( float $x1 , float $y1 , float $x , float $y )
bool pathCurveToQuadraticBezierRelative ( float $x1 , float $y1 , float $x , float $y )
bool pathCurveToQuadraticBezierSmoothAbsolute ( float $x , float $y )
bool pathCurveToQuadraticBezierSmoothRelative ( float $x , float $y )
bool pathCurveToRelative ( float $x1 , float $y1 , float $x2 , float $y2 , float $x , float $y )
bool pathCurveToSmoothAbsolute ( float $x2 , float $y2 , float $x , float $y )
bool pathCurveToSmoothRelative ( float $x2 , float $y2 , float $x , float $y )

{\fn黑体\fs22\bord1\shad0\3aHBE\4aH00\fscx67\fscy66\2cHFFFFFF\3cH808080}哪个是?

The curveTo() method draws a quadratic Bézier curve. This draws an arc that connects two points (called anchor points) while bending toward a third point (called the control point). The Graphics object uses the current drawing position as the first anchor point. When you call the curveTo() method, you pass four parameters: the x and y coordinates of the control point, followed by the x and y coordinates of the second anchor point. For example, the following code draws a curve starting at point 100, 100 and ending at point 200, 200. Because the control point is at point 175, 125, this creates a curve that moves to the right and then downward:

AS3 实施(flash.display.Graphics) :

curveTo(controlX:Number, controlY:Number, anchorX:Number, anchorY:Number):void

"http://php.net/manual/en/imagickdraw.pathcurvetoquadaritibeerabsolute.php" rel=“无跟踪”>PHPP执行 :

bool ImagickDraw::pathCurveToQuadraticBezierAbsolute ( float $x1 , float $y1 , float $x , float $y )
