PHP | ImagickDraw translate() Function

The ImagickDraw::translate() function is an inbuilt function in PHP which is used to apply a translation to the current coordinate system. It applies a translation to the current coordinate system which moves the coordinate system origin to the specified coordinate.

Syntax:

bool ImagickDraw::translate( $x, $y )

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

• $x: This parameter is used to hold the value of x translation coordinate.
• $y: This parameter is used to hold the value of y translation coordinate.

Return Value: This function does not return any value.

Below programs illustrates the ImagickDraw::translate() function in PHP:

Program 1:

<?php

// require_once('path/vendor/autoload.php');

// Create a ImagickDraw object to draw into.
$draw = new ImagickDraw();

// Set the stroke color
$draw->setStrokeColor('black');

// Set the Image Filled Color
$draw->setFillColor('red');

// Draw the circle
$draw->circle(250, 250, 100, 150);

// Set the Image Filled Color
$draw->setFillColor('green');

// Set the translation points
$draw->translate(90, 30);

// Draw the circle
$draw->circle(350, 350, 250, 350);

// Create new imagick object
$image = new Imagick();

// Set the dimensions of the image
$image->newImage(500, 500, 'white');

// Set the image format
$image->setImageFormat("png");

// Draw the image
$image->drawImage($draw);
header("Content-Type: image/png");

// Display the image
echo $image->getImageBlob();
?>

Output:

Program 2:

<?php

// require_once('path/vendor/autoload.php');

// Create a ImagickDraw object to draw into.
$draw = new ImagickDraw();

// Set the Stroke color
$draw->setStrokeColor('black');

// Set the image filled color
$draw->setFillColor('red');
$points = [['x' => 40 * 5, 'y' => 10 * 5],
           ['x' => 70 * 5, 'y' => 50 * 5],
           ['x' => 60 * 5, 'y' => 15 * 5], ];

// Draw the polygon
$draw->polygon($points);

// Set the image filled color
$draw->setFillColor('green');

// Set the translation points
$draw->translate(10, 30);
$points = [['x' => 40 * 5, 'y' => 10 * 5],
           ['x' => 70 * 5, 'y' => 50 * 5],
           ['x' => 60 * 5, 'y' => 15 * 5], ];

// Draw the polygon
$draw->polygon($points);

// Set the image filled color
$draw->setFillColor('blue');

// Set the translation points
$draw->translate(10, 30);
$points = [['x' => 40 * 5, 'y' => 10 * 5],
           ['x' => 70 * 5, 'y' => 50 * 5],
           ['x' => 60 * 5, 'y' => 15 * 5], ];

// Draw the polygon
$draw->polygon($points);

// Set the image filled color
$draw->setFillColor('yellow');

// Set the translation points
$draw->translate(10, 30);
$points = [['x' => 40 * 5, 'y' => 10 * 5],
           ['x' => 70 * 5, 'y' => 50 * 5],
           ['x' => 60 * 5, 'y' => 15 * 5], ];

// Draw the polygon
$draw->polygon($points);

// Create new imagick object
$image = new Imagick();

// Set the image dimensions
$image->newImage(400, 400, 'white');

// Set the image format
$image->setImageFormat("png");

// Draw the image
$image->drawImage($draw);
header("Content-Type: image/png");

// Display the image
echo $image->getImageBlob();
?>
