(PECL imagick 2.0.0)
Imagick::shearImage — Creating a parallelogram
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
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.
