Imagick::shearImage

(PECL imagick 2, PECL imagick 3)

Imagick::shearImage — Creating a parallelogram

Description

public Imagick::shearImage(mixed $background, float $x_shear, float $y_shear): bool

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.

Parameters

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

Return Values

Returns true on success.

Changelog

Version	Description
PECL imagick 2.1.0	Now allows a string representing the color as the first parameter. Previous versions allow only an ImagickPixel object.

Examples

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();
}

?>
