The ImagickDraw::pathEllipticArcAbsolute() function is an inbuilt function in PHP which is used to draw an elliptical arc from the current point to (x, y) using absolute coordinates.
Syntax:
bool ImagickDraw::pathEllipticArcAbsolute( float $rx, float $ry, float $x_axis_rotation, bool $large_arc_flag, bool $sweep_flag, float $x, float $y )
Parameters: This function accepts seven parameters as mentioned above and described below:
- $rx: It specifies the x-radius.
- $ry: It specifies the y-radius
- $x_axis_rotation: It specifies x-axis rotation
- $large_arc_flag: It specifies whether to draw the larger of the available arcs.
- $sweep_flag: It specifies whether to draw the arc matching a clock-wise rotation.
- $x: It specifies the x-coordinate.
- $y: It specifies the y-coordinate.
Return Value: This function returns TRUE on success.
Exceptions: This function throws ImagickException on error.
Below given programs illustrate the ImagickDraw::pathEllipticArcAbsolute() function in PHP:
Program 1:
<?php   // Create a new imagick object $imagick = new Imagick();   // Create a image on imagick object $imagick->newImage(800, 250, 'green');   // Create a new ImagickDraw object $draw = new ImagickDraw();   $draw->setFillColor('blue');   // Set the stroke color $draw->setStrokeColor('red');   // Set the stroke width $draw->setStrokeWidth(15);   // Draw elliptic arc $draw->pathStart(); $draw->pathEllipticArcAbsolute(420, 250, 10, true, true, 40, 40); $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   // Create a new imagick object $imagick = new Imagick();   // Create a image on imagick object $imagick->newImage(800, 250, '#E57733');   // Create a new ImagickDraw object $draw = new ImagickDraw();   // Set the width of stroke $draw->setStrokeWidth(1);   // Set the color of stroke $draw->setStrokeColor('#E57733');   // Set the fill color $draw->setFillColor('black');   // Set the fill rule $draw->setFillRule(Imagick::FILLRULE_NONZERO);   // Draw a sunset cartoon $draw->pathStart(); $draw->pathMoveToAbsolute(0, 100); $draw->pathEllipticArcAbsolute(420, 400, 410, true, true, 0, 900); $draw->pathMoveToAbsolute(300, 250); $draw->pathEllipticArcAbsolute(420, 600, 410, true, true, 0, 900); $draw->pathClose(); $draw->pathFinish(); $draw->setFillColor('yellow'); $draw->translate(30, 0); $draw->circle(300, 100, 300, 150);   // Render the draw commands $imagick->drawImage($draw);   // Show the output $imagick->setImageFormat('png'); header("Content-Type: image/png"); echo $imagick->getImageBlob(); ?> |
