Gmagick::shearimage
Creating a parallelogram
Description
public Gmagick Gmagick::shearimage(mixed $color, float $xShear, float $yShear)
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.
