PHP | ImagickDraw pathCurveToSmoothAbsolute() Function

The ImagickDraw::pathCurveToSmoothAbsolute() function is an inbuilt function in PHP which is used to draw a cubic Bezier curve from the current point to (x, y) using absolute coordinates.

Syntax:

bool ImagickDraw::pathCurveToSmoothAbsolute
( float $x2, float $y2, float $x, float $y )

Parameters: This function accepts four parameters as mentioned above and described below:

  • $x2: It specifies the x-coordinate of the second control point.
  • $y2: It specifies the y-coordinate of the second control point.
  • $x: It specifies the x-coordinate of the ending point.
  • $y: It specifies the y-coordinate of the ending point.

Return Value: This function returns TRUE on success.

Exceptions: This function throws ImagickException on error.
