Imagick::shearImage

(PECL imagick 2.0.0)
Creating a parallelogram
bool Imagick::shearImage ( mixed $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.

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

Returns:

Returns TRUE on success.

Changelog:
2.1.0

Now allows a string representing the color as the first parameter. Previous versions allow only an ImagickPixel object.

Examples:
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();
}

?>
