Imagick::shearImage — Creating a parallelogram

说明

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.

参数

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

返回值

成功时返回 TRUE。

2.1.0	Now allows a string representing the color as the first parameter. Previous versions allow only an ImagickPixel object.
