PHP | ImagickDraw pathMoveToRelative() Function

Last Updated : 23 Dec, 2019

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

bool ImagickDraw::pathMoveToRelative( 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::pathMoveToRelative() function in PHP: Program 1:

php

<?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, 100)
$draw->pathMoveToRelative(400, 100);

// Setting the end point to (500, 100)
$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

<?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->setFillColor('red');

$draw->pathStart();

// Setting the stating point to (400, 100), draw a rectangle
$draw->pathMoveToRelative(400, 100);
$draw->pathLineToAbsolute(400, 200);
$draw->pathLineToAbsolute(300, 200);
$draw->pathLineToAbsolute(300, 100);

$draw->pathFinish();

// Render the draw commands
$imagick->drawImage($draw);

// Show the output
$imagick->setImageFormat('png');
header("Content-Type: image/png");
echo $imagick->getImageBlob();
?>
