## Name

lqr_carver_get_ref_height — get the reference height of a `LqrCarver` object

## Synopsis

    #include <lqr.h>

`gint lqr_carver_get_ref_height(` | LqrCarver* carver`)`;

## Description

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.
