Crate inkswatch_colorscan 

Scan Colors

A Rust crate for analyzing fountain pen ink colors from digital photographs.

This library provides calibrated color measurement by:

• Detecting and rectifying paper/card surfaces
• Estimating illuminant and applying white balance correction
• Isolating ink swatches from background
• Extracting representative colors with confidence metrics

Example

use inkswatch_colorscan::{analyze_swatch, ColorResult};
use std::path::Path;

let result = analyze_swatch(Path::new("photo.jpg"))?;
println!("Lab: {:?}, Hex: {}", result.lab, result.hex);

Re-exports

pub use error::AnalysisError;

pub use error::Result;

pub use config::PipelineConfig;
