The ImagickDraw::skewX() function is an inbuilt function in PHP which is used to skews the current coordinate system in the horizontal direction.

Syntax:

Parameters: This function accepts a single parameter $degrees which is used to hold the degrees to skew.

Return Value: This function does not return any value.

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

Program 1:

<?php

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

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

// Set the image filled color
$draw->setFillColor('blue');
$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('red');
$draw->skewX(-60);
$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');
$draw->skewX(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();
$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 an ImagickDraw object
$draw = new ImagickDraw();

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

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

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

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

// Set the skew of X
$draw->skewX(30);

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

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

// Set the skew of X
$draw->skewX(30);

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

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

// Create new image of given size
$image->newImage(900, 600, 'white');

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

// Draw the image
$image->drawImage($draw);

header("Content-Type: image/png");

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

Output:
