The ImagickDraw::skewY() function is an inbuilt function in PHP which is used to skews the current coordinate system in the vertical direction. Syntax:
bool ImagickDraw::skewY( $degrees )
Parameters: This function accepts a single parameter $degrees which is used to hold the degrees to skew. Return Value: This function does not return return any value. Below programs illustrate the ImagickDraw::skewY() function in PHP: Program 1: php
<?php

// require_once('path/vendor/autoload.php');
 
// Create an ImagickDraw object.
$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->skewY(-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->skewY(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(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: skewY Program 2: php
<?php

// require_once('path/vendor/autoload.php');
 
// Create an ImagickDraw object
$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');
$draw->skewY(-30);
 
// Draw the circle
$draw->circle(250, 250, 100, 150); 
 
// Set the image filled color
$draw->setFillColor('yellow');
$draw->skewY(-60);
 
// Draw the circle
$draw->circle(250, 250, 100, 150); 
 
// Create new Imagick object 
$image = new Imagick();
 
// Set the image dimensions
$image->newImage(700, 700, '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: skewY Reference: https://www.php.net/manual/en/imagickdraw.skewy.php
