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   // 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 // Create a new imagick object $imagick = new Imagick(); Â Â // Create a image on imagick object $imagick->newImage(800, 250, 'black'); Â Â // Create a new ImagickDraw object $draw = new ImagickDraw(); Â Â $draw->setFillColor('black'); Â Â // Set the stroke color $draw->setStrokeColor('pink'); Â Â // 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(); Â Â // Render the draw commands $imagick->drawImage($draw); Â Â // Show the output $imagick->setImageFormat('png'); header("Content-Type: image/png"); echo $imagick->getImageBlob(); ?> |
