Gmagick::shearimage — Creating a parallelogram

Beschreibung

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.

Parameter-Liste

color: The background pixel wand.
xShear: The number of degrees to shear the image.
yShear: The number of degrees to shear the image.
