Imagick::liquidRescaleImage — Animates an image or images
说明
public 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。
