The ImagickDraw::pathCurveToQuadraticBezierSmoothAbsolute() function is an inbuilt function in PHP which is used to draw a quadratic Bezier curve which is a parametric curve. This function can continue a curve from a quadratic curve smoothly.
Syntax:
bool ImagickDraw::pathCurveToQuadraticBezierSmoothAbsolute( 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 the ending y-coordinate
Return Value: This function returns TRUE on success.
Exceptions: This function throws ImagickException on error.
Below given programs illustrate the ImagickDraw::pathCurveToQuadraticBezierSmoothAbsolute() function in PHP:
Program 1:
<?php
$imagick = new Imagick();
$imagick ->newImage(800, 250, 'black' );
$draw = new ImagickDraw();
$draw ->setFillColor( 'black' );
$draw ->setStrokeColor( 'red' );
$draw ->pathStart();
$draw ->pathCurveToQuadraticBezierSmoothAbsolute(3950, 250);
$draw ->pathCurveToQuadraticBezierSmoothAbsolute(2950, 250);
$draw ->pathCurveToQuadraticBezierSmoothAbsolute(390, 250);
$draw ->pathFinish();
$imagick ->drawImage( $draw );
$imagick ->setImageFormat( 'png' );
header( "Content-Type: image/png" );
echo $imagick ->getImageBlob();
?>
|
Output:
Program 2:
<?php
$imagick = new Imagick();
$imagick ->newImage(800, 250, 'black' );
$draw = new ImagickDraw();
$draw ->setFillColor( 'black' );
$draw ->setStrokeColor( 'yellow' );
$draw ->pathStart();
$draw ->pathCurveToQuadraticBezierSmoothAbsolute(3950, 250);
$draw ->pathCurveToQuadraticBezierSmoothAbsolute(950, 250);
$draw ->pathCurveToQuadraticBezierSmoothAbsolute(2390, 250);
$draw ->pathClose();
$draw ->pathFinish();
$imagick ->drawImage( $draw );
$imagick ->setImageFormat( 'png' );
header( "Content-Type: image/png" );
echo $imagick ->getImageBlob();
?>
