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 )

Which one is it ? Any ideas ?? Because I’m pretty lost.

Flash curveTo is a quadratic Bézier curve, equivalent to php ImagickDraw::pathCurveToQuadraticBezierAbsolute

Abode: Drawing lines and curves

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 implementation (flash.display.Graphics):

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

PHP implementation:

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