Imagick::shearImage — Creating a parallelogram
$background
, float $x_shear
, float $y_shear
)Slides one edge of an image along the X or Y axis, creating a parallelogram. An X direction shear slides an edge along the X axis, while a Y direction shear slides an edge along the Y axis. The amount of the shear is controlled by a shear angle. For X direction shears, x_shear is measured relative to the Y axis, and similarly, for Y direction shears y_shear is measured relative to the X axis. Empty triangles left over from shearing the image are filled with the background color.
background
The background color
x_shear
The number of degrees to shear on the x axis
y_shear
The number of degrees to shear on the y axis

2.1.0 | Now allows a string representing the color as the first parameter. Previous versions allow only an ImagickPixel object. |
Example #1 Imagick::shearImage()
<?php
function shearImage ( $imagePath , $color , $shearX , $shearY ) {
$imagick = new \ Imagick ( realpath ( $imagePath ));
$imagick -> shearimage ( $color , $shearX , $shearY );
header ( "Content-Type: image/jpg" );
echo $imagick -> getImageBlob ();
}
?>
