LQR_CARVER_SET_ENL_STEP(3)				     LqR library API reference					LQR_CARVER_SET_ENL_STEP(3)

NAME

       lqr_carver_set_enl_step - set the enlargement step of a LqrCarver object

SYNOPSIS

       #include <lqr.h>

       LqrRetVal lqr_carver_set_enl_step(LqrCarver* carver, gfloat enl_step);

DESCRIPTION

       The function lqr_carver_set_enl_step sets the enlargement step of the LqrCarver object pointed to by carver to the value specified in
       enl_step, which must be strictly greater than 1 and less than 2.

       The enlargement step is the maximum enlargement ratio (with respect to either the original width or original height of carver) which the
       function lqr_carver_resize applies in a single step; if that function is asked a greater enlargement, it divides the process in multiple
       steps (and updates the original sizes accordingly at each new step - these can be readout at any time with lqr_carver_get_ref_width(3) and
       lqr_carver_get_ref_height(3)).

       The default value for new LqrCarver objects is 2.0.

RETURN VALUE

       The return value follows the Liquid Rescale library signalling system.  LQR_ERROR is returned if the enl_step parameter is out of bounds.
