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   // 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('red');   // Draw curves to Quadratic Bezier Smooth Absolute (without pathClose()) $draw->pathStart(); $draw->pathCurveToQuadraticBezierSmoothAbsolute(3950, 250); $draw->pathCurveToQuadraticBezierSmoothAbsolute(2950, 250); $draw->pathCurveToQuadraticBezierSmoothAbsolute(390, 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   // 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('yellow');   // Draw curves to Quadratic Bezier Smooth Absolute (with pathClose()) $draw->pathStart(); $draw->pathCurveToQuadraticBezierSmoothAbsolute(3950, 250); $draw->pathCurveToQuadraticBezierSmoothAbsolute(950, 250); $draw->pathCurveToQuadraticBezierSmoothAbsolute(2390, 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(); ?> |
