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).

NAME

       lqr_carver_set_dump_vmaps, lqr_carver_set_no_dump_vmaps - set the visibility maps autodump for an LqrCarver object

SYNOPSIS

       #include <lqr.h>

       void lqr_carver_set_dump_vmaps(LqrCarver* carver);

       void lqr_carver_set_no_dump_vmaps(LqrCarver* carver);

DESCRIPTION

       Invoking function lqr_carver_set_dump_vmaps over the LqrCarver object pointed to by carver has the effect of activating the automatic
       dumping of visibility maps at each rescale operation (which by default is turned off).

       Rescale operations involving both directions will dump two maps.

       The dumped maps will be attached to the LqrCarver object and can be accessed at any later time using the functions lqr_vmap_list_foreach(3)
       or a combination of lqr_vmap_list_start(3), lqr_vmap_list_current(3) and lqr_vmap_list_next(3).

       Using this setting is pointless if the LqrCarver object is not initialised.

       The function lqr_carver_set_no_dump_vmaps reverts the effect of the previous one (but the maps dumped so far will be kept).

       Note that it is also possible to dump the visibility maps manually; however, using the automatic dump is the only way to get intermidiate
       maps when the function lqr_carver_resize(3) performs the rescaling in both directions, or in more than one step.
