$yRadius : float
$xAxisAngle : float
$largeArc : bool
$sweep : bool
$x : float
$y : float
Return values

toCurves()

Converts the elliptic arc to multiple curves.

public toCurves(float $fromX, float $fromY) : array<string|int, \BaconQrCode\Renderer\Path\Curve|\BaconQrCode\Renderer\Path\Line>

Since not all image back ends support elliptic arcs, this method allows to convert the arc into multiple curves resembling the same result.

Parameters
$fromX : float
$fromY : float
