PHP | ImagickDraw pathCurveToQuadraticBezierSmoothRelative() Function

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

bool ImagickDraw::pathCurveToQuadraticBezierSmoothRelative( float $x, float $y )

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

• $x: It specifies the ending x-coordinate.
• $y: It specifies ending y-coordinate.

Return Value: This function returns TRUE on success. Exceptions: This function throws ImagickException on error. Below given programs illustrate the ImagickDraw::pathCurveToQuadraticBezierSmoothRelative() 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('black');

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

// Draw curves to Quadratic Bezier Smooth Relative (without pathClose())
$draw->pathStart();
$draw->pathCurveToQuadraticBezierSmoothRelative(950, 250);
$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('black');

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

// Draw curves to Quadratic Bezier Smooth Relative (with pathClose())
$draw->pathStart();
$draw->pathCurveToQuadraticBezierSmoothRelative(3950, 250);
$draw->pathCurveToQuadraticBezierSmoothRelative(950, 250);
$draw->pathCurveToQuadraticBezierSmoothRelative(-2000, 250);
$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();
?>
