PHP | ImagickDraw pathMoveToAbsolute() Function

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();
?>

Output:
