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. Below given programs illustrate the ImagickDraw::pathCurveToSmoothAbsolute() function in PHP: Program 1: php
<?php

// Create a new imagick object
$imagick = new Imagick();

// Create a image on imagick object
$imagick->newImage(800, 250, 'black');

// Create a new ImagickDraw object
$draw = new ImagickDraw();

$draw->setFillColor('blue');

// Set the stroke color
$draw->setStrokeColor('white');

// Draw curves to Quadratic Bezier Relative (with pathClose())
$draw->pathStart();
$draw->pathCurveToSmoothAbsolute(50, 250, 1900, 20);
$draw->pathClose();
$draw->pathFinish();

// Render the draw commands
$imagick->drawImage($draw);

// Show the output
$imagick->setImageFormat('png');
header("Content-Type: image/png");
echo $imagick->getImageBlob();
?>
Output: Program 2: php
<?php

// Create a new imagick object
$imagick = new Imagick();

// Create a image on imagick object
$imagick->newImage(800, 250, 'black');

// Create a new ImagickDraw object
$draw = new ImagickDraw();

$draw->setFillColor('blue');

// Set the stroke color
$draw->setStrokeColor('white');

// Draw curves to Quadratic Bezier Relative (without pathClose())
$draw->pathStart();
$draw->pathCurveToSmoothAbsolute(150, 250, 800, 250);
$draw->pathFinish();

// Render the draw commands
$imagick->drawImage($draw);

// Show the output
$imagick->setImageFormat('png');
header("Content-Type: image/png");
echo $imagick->getImageBlob();
?>
