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. Diese Funktion ist verfügbar, wenn Imagick gegen die ImageMagick-Version 6.3.9 oder höher kompiliert wurde.

heightThe height of the target size
delta_xHow much the seam can traverse on x-axis. Passing 0 causes the seams to be straight.
