Implementations§

impl ImageNormalizer

pub fn normalize( input_path: &Path, output_path: &Path, options: &NormalizeOptions, ) -> Result<NormalizeResult>

pub fn normalize_with_shift( input_path: &Path, output_path: &Path, options: &NormalizeOptions, shift_x: i32, shift_y: i32, custom_scale: Option<f64>, ) -> Result<NormalizeResult>

Normalize with shift (for final output with page offset correction)

pub fn estimate_paper_color(image: &RgbImage) -> PaperColor

Estimate paper color from entire image

pub fn sample_corner_colors( image: &RgbImage, patch_percent: u32, ) -> CornerColors

Sample paper colors from image corners
