Name

lqr_carver_init — activates an LqrCarver object

Synopsis

#include <lqr.h>
LqrRetVal lqr_carver_init(LqrCarver* carver,
 gint delta_x,
 gfloat rigidity);
 

Description

The function lqr_carver_init initialises the LqrCarver pointed to by carver, so that it can compute the visibility maps as needed upon calls of lqr_carver_resize.

The parameter delta_x controls the maximum transversal step a seam can make. A value of 0 means straight seams. Normally, it is set to 1.

The parameter rigidity can be used to add a negative bias to non-straight seams, and it is normally set to 0.

Visibility maps must not be loaded with the function lqr_vmap_load when using this function, neither before nor after invoking it.

Return value

The return value follows the Liquid Rescale library signalling system.
