[−][src]Function imagequant_sys::liq_set_dithering_level
pub unsafe extern "C" fn liq_set_dithering_level(
res: &mut liq_result,
dither_level: f32
) -> liq_error
Enables/disables dithering in liq_write_remapped_image()
.
Dithering level must be between 0
and 1
(inclusive). Dithering level 0
enables fast non-dithered remapping. Otherwise a variation of Floyd-Steinberg error diffusion is used.
Precision of the dithering algorithm depends on the speed setting, see liq_set_speed()
.
Returns LIQ_VALUE_OUT_OF_RANGE
if the dithering level is outside the 0-1 range.
