Imagick::liquidRescaleImage — Animates an image or images

Opis

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

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. Ta metoda jest dostępna, jeśli rozszerzenie Imagick zostało skompilowane z ImageMagick w wersji 6.3.9 lub nowszej.

Parametry

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.

Zwracane wartości

Zwraca TRUE w przypadku sukcesu.
