Imagick::liquidRescaleImage — Animates an image or images
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。
widthThe width of the target size
heightThe height of the target size
delta_xHow much the seam can traverse on x-axis. Passing 0 causes the seams to be straight.
