Gmagick::shearimage()
(PECL gmagick >= Unknown)
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.
