Function imageproc::contrast::stretch_contrast_mut

pub fn stretch_contrast_mut(
    image: &mut GrayImage,
    input_min: u8,
    input_max: u8,
    output_min: u8,
    output_max: u8
)

Stretches the contrast in an image, linearly mapping intensities in (input_lower, input_upper) to (output_lower, output_upper) and saturating values outside this input range.

See the stretch_contrast documentation for more.

Panics

If input_lower >= input_upper or output_lower > output_upper.
