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.
