Imagick::liquidRescaleImage — Animates an image or images

说明

Imagick::liquidRescaleImage ( int $width , int $height , float $delta_x , float $rigidity ) : bool

This method scales the images using liquid rescaling method. This method is an implementation of a technique called seam carving. In order for this method to work as expected ImageMagick must be compiled with liblqr support. 此方法在Imagick基于ImageMagick 6.3.9以上版本编译时可用。

参数

width: The width of the target size
height: The height of the target size
delta_x: How much the seam can traverse on x-axis. Passing 0 causes the seams to be straight.
rigidity: Introduces a bias for non-straight seams. This parameter is typically 0.

返回值

成功时返回 TRUE。
