Imagick Functions

Imagick::shearImage

Description:

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

String or ImagickPixel object representing 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.

Example

<?php
$image = new Imagick("opossum.jpg"); 
# change to GIF for transparency
$image->setimageformat("gif");
$image->shearImage("transparent", 20,40);
header("content-type:image/gif");
echo $image;
?>
