Gmagick::shearimage — Creating a parallelogram

说明

public Gmagick::shearimage ( mixed $color , float $xShear , float $yShear ) : Gmagick

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.

参数

color

The background pixel wand.

xShear

The number of degrees to shear the image.

yShear

The number of degrees to shear the image.
