0 0 1 minute read

The ImagickDraw::pathEllipticArcRelative() function is an inbuilt function in PHP which is used to draw an elliptical arc from the current point to (x, y) using relative coordinates.

Syntax:

bool ImagickDraw::pathEllipticArcRelative( float $rx, float $ry,
         float $x_axis_rotation, bool $large_arc_flag, bool $sweep_flag, float $x )

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 programs illustrate the ImagickDraw::pathEllipticArcRelative() function in PHP:

Program 1:

<?php 
  
// Create a new imagick object 
$imagick = new Imagick(); 
  
// Create a image on imagick object 
$imagick->newImage(800, 250, '#7441e0'); 
  
// Create a new ImagickDraw object 
$draw = new ImagickDraw(); 
  
$draw->setFillColor('#2fceeb'); 
  
// Set the stroke color 
$draw->setStrokeColor('#c27230'); 
  
// Set the stroke width 
$draw->setStrokeWidth(15); 
  
// Draw elliptic arc 
$draw->pathStart(); 
$draw->pathEllipticArcRelative(120, 9250, 
               210, false, true, 300, 400); 
$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, '#7441e0'); 
  
// Create a new ImagickDraw object 
$draw = new ImagickDraw(); 
  
$draw->setFillColor('#2fceeb'); 
  
// Set the stroke color 
$draw->setStrokeColor('#c27230'); 
  
// Set the stroke width 
$draw->setStrokeWidth(15); 
  
// Draw elliptic arc 
$draw->pathStart(); 
$draw->pathEllipticArcRelative(120, 
         50, 10, true, true, 300, 400); 
$draw->pathFinish(); 
  
// Render the draw commands 
$imagick->drawImage($draw); 
  
// Show the output 
$imagick->setImageFormat('png'); 
header("Content-Type: image/png"); 
echo $imagick->getImageBlob(); 
?> 

Output:
