PHP | ImagickDraw pathLineToAbsolute() Function

The ImagickDraw::pathLineToAbsolute() function is an inbuilt function in PHP which is used to draw a line path from the current point to the given coordinate using absolute coordinates. The coordinate then becomes the new current point. The initial point can be set using pathMoveToAbsolute() function.

Syntax:

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

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

• $x: It specifies the starting x-coordinate.
• $y: It specifies the starting y-coordinate.

Return Value: This function returns TRUE on success.

Below programs illustrate the ImagickDraw::pathLineToAbsolute() 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 fill color
$draw->setFillColor('black');

// Create a path
$draw->pathStart();

// Use 50, 50 as start point
$draw->pathMoveToAbsolute(50, 50);

// Use 100, 150 as end point
$draw->pathLineToAbsolute(100, 150);

// End the path
$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();

// Set the fill color
$draw->setFillColor('black');

// Create a path
$draw->pathStart();

// Draw a triangle
// First corner
$draw->pathMoveToAbsolute(350, 50);

// Second corner
$draw->pathLineToAbsolute(250, 150);

// Third corner
$draw->pathLineToAbsolute(350, 150);

// End the path
$draw->pathFinish();

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

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

Output:
