The Gmagick::shearimage() function is an inbuilt function in PHP which is used to slide one edge of an image along the X or Y axis to create a parallelogram. The X-direction shear slides an edge along the X-axis, while a Y direction shear slides an edge along the Y-axis. The shear angle is used to set shear of the image.
Syntax:

Gmagick Gmagick::shearimage( $color, $xShear, $yShear )

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

$color: This parameter is used to set the background color.
$xShear: This parameter is used to set degrees to x-shear of the image.
$yShear: This parameter is used to set degrees to y-shear of the image.

Return Value: This function returns the Gmagick object on success.
Errors/Exceptions: This function throws GmagickException on error.
Below programs illustrates the Gmagick::shearimage() function in PHP:
Program 1:
Input Image:

Program 2:

php

<?php 
    
// Create a GmagickDraw object 
$draw = new GmagickDraw(); 
   
// Create GmagickPixel object

$gmagick = new Gmagick(); 
$gmagick->newImage(500, 500, 'White'); 
$gmagick->setImageFormat("png"); 
$gmagick->drawImage($draw); 
 
// Shear the image
$gmagick->shearimage('yellow', 20, 40);
  
// Display the output image 
header("Content-Type: image/png"); 
echo $gmagick->getImageBlob(); 
?>
