Opis

ImagickDraw::pathCurveToQuadraticBezierSmoothRelative ( float `\$x` , float `\$y` ) : bool
Ostrzeżenie

Ta funkcja jest obecnie nieudokumentowana, dostępna jest jedynie lista jej argumentów.

Draws a quadratic Bezier curve (using relative coordinates) from the current point to (x, y). The control point is assumed to be the reflection of the control point on the previous command relative to the current point. (If there is no previous command or if the previous command was not a DrawPathCurveToQuadraticBezierAbsolute, DrawPathCurveToQuadraticBezierRelative, DrawPathCurveToQuadraticBezierSmoothAbsolut or DrawPathCurveToQuadraticBezierSmoothRelative, assume the control point is coincident with the current point). At the end of the command, the new current point becomes the final (x, y) coordinate pair used in the polybezier.

This function cannot be used to continue a cubic Bezier curve smoothly. It can only continue from a quadratic curve smoothly.

Parametry

`x`

ending x coordinate

`y`

ending y coordinate
