.SH "DESCRIPTION"
.PP
Invoking function
\fBlqr_carver_set_dump_vmaps\fR
over the
LqrCarver
object pointed to by
\fIcarver\fR
has the effect of activating the automatic dumping of visibility maps at each rescale operation (which by default is turned off)\&.
.PP
Rescale operations involving both directions will dump two maps\&.
.PP
The dumped maps will be attached to the
LqrCarver
object and can be accessed at any later time using the functions
\fBlqr_vmap_list_foreach\fR(3)
or a combination of
\fBlqr_vmap_list_start\fR(3),
\fBlqr_vmap_list_current\fR(3)
and
\fBlqr_vmap_list_next\fR(3)\&.
.PP
Using this setting is pointless if the
LqrCarver
object is not initialised\&.
.PP
The function
\fBlqr_carver_set_no_dump_vmaps\fR
reverts the effect of the previous one (but the maps dumped so far will be kept)\&.
.PP
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
\fBlqr_carver_resize\fR(3)
performs the rescaling in both directions, or in more than one step\&.
