LQR_CARVER_INIT(3) LqR library API reference LQR_CARVER_INIT(3) 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. SEE ALSO

LQR_CARVER_SET_PRESERVE_INP(3) LqR library API reference LQR_CARVER_SET_PRESERVE_INP(3) NAME
lqr_carver_set_preserve_input_image - set a flag to preserve the buffer passed to a LqrCarver object upon creation SYNOPSIS
#include <lqr.h> void lqr_carver_set_preserve_input_image(LqrCarver* carver); DESCRIPTION
The function lqr_carver_set_preserve_input_image flags the LqrCarver object pointed to by carver so that it does not alter in any way the buffer which is passed to it by the constructor. It must be used before any resizing-related operation takes place, either after the carver construction or after the calls to lqr_carver_init(3) or lqr_vmap_load(3). SEE ALSO
