lqr_carver_get_ref_height — get the reference height of a LqrCarver
object
#include <lqr.h>
gint lqr_carver_get_ref_height( | LqrCarver* carver) ; |
The function lqr_carver_get_ref_height
returns
the internal reference height of the image contained in the LqrCarver
object
pointed to by carver
, in pixel units.
The reference height is set as the original height at carver initialization,
and reset any time the carver gets subsequently flattened, either
explicitly through lqr_carver_flatten
(3) or implicitly
when the rescale direction changes or an enlargment beyond the
maximum enlargement step is performed.
