Imagick::shadeImage — Creates a 3D effect
$gray, float $azimuth, float $elevation): bool
Shines a distant light on an image to create a three-dimensional effect. You control the positioning of the light with azimuth and elevation; azimuth is measured in degrees off the x axis and elevation is measured in pixels above the Z axis. 此方法在Imagick基于ImageMagick 6.2.9以上版本编译时可用。
gray
A value other than zero shades the intensity of each pixel.
azimuth
Defines the light source direction.
elevation
Defines the light source direction.
成功时返回 true。
Throws ImagickException on failure.
