lqr_carver_set_enl_step — set the enlargement step of a LqrCarver
object
#include <lqr.h>
LqrRetVal lqr_carver_set_enl_step( | LqrCarver* carver, |
gfloat enl_step) ; |
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.
