PHP | ImagickDraw pathMoveToAbsolute() Function

0 0 1 minute read

The ImagickDraw::pathMoveToAbsolute() function is an inbuilt function in PHP which is used to start a new sub-path at the given coordinate using absolute coordinates. The current point then becomes the specified coordinate. This function is used for setting initial coordinates before starting drawing anything.

Syntax:

bool ImagickDraw::pathMoveToAbsolute( float $x, float $y )

Parameters:This function accepts two parameters as mentioned above and described below:

$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::pathMoveToAbsolute() function in PHP:
Program 1:

<?php 
  
// Create a new imagick object 
$imagick = new Imagick(); 
  
// Create a image on imagick object 
$imagick->newImage(800, 250, 'white'); 
  
// Create a new ImagickDraw object 
$draw = new ImagickDraw(); 
  
// Set the stroke width 
$draw->setStrokeWidth(30); 
  
$draw->pathStart(); 
  
// Setting the stating point to (400, 40) 
$draw->pathMoveToAbsolute(400, 40); 
  
// Setting the end point to (500, 40) 
$draw->pathLineToHorizontalAbsolute(500); 
$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, 'white'); 
   
// Create a new ImagickDraw object 
$draw = new ImagickDraw(); 
   
$color = ['blue', 'red', 'green']; 
   
// Set the stroke width 
$draw->setStrokeWidth(5); 
   
// Draw lines 
for ($x = 0; $x < 20; $x++) { 
    $draw->setStrokeColor($color[$x % 3]); 
    $draw->pathStart(); 
    // Moving to next vertical line 
    $draw->pathMoveToAbsolute($x * 40, 0); 
    $draw->pathLineToVerticalRelative(800); 
    $draw->pathFinish(); 
} 
for ($x = 0; $x < 20; $x++) { 
    $draw->setStrokeColor($color[$x % 3]); 
    $draw->pathStart(); 
    // Moving to next horizontal line 
    $draw->pathMoveToAbsolute(0, $x * 40); 
    $draw->pathLineToHorizontalRelative(800); 
    $draw->pathFinish(); 
   
} 
   
// Render the draw commands 
$imagick->drawImage($draw); 
   
// Show the output 
$imagick->setImageFormat('png'); 
header("Content-Type: image/png"); 
echo $imagick->getImageBlob(); 
?>
