Imagick::shearImage

(PECL imagick 2.0.0)

Imagick::shearImageCreating a parallelogram

Description

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

This function is currently not documented; only its argument list is available.

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.
