1//! Image transformation and processing pipeline.
2//!
3//! This module provides the core building blocks for transforming raw sensor data
4//! (like Bayer CFA) into viewable RGB images. These transforms are generic and
5//! designed to support various RAW formats (ARW, DNG, CR2, NEF, etc.).
6//!
7//! # General RAW Processing Flow
8//! Most RAW formats follow a similar processing pipeline:
9//!
10//! 1. **Sensor Normalization**:
11//!    - **Black Level**: Subtracting the sensor noise floor (pedestal).
12//!    - **White Level**: Normalizing signal to a standard range (0.0 - 1.0).
13//!    - See [`black_level`].
14//!
15//! 2. **Demosaicing**:
16//!    - Converting incomplete Color Filter Array (CFA) data (e.g., Bayer) into
17//!      fully populated RGB pixels.
18//!    - See [`cfa`].
19//!
20//! 3. **Color Processing**:
21//!    - **White Balance**: Adjusting gains for Red/Blue channels to neutralize color casts.
22//!    - **Color Transformation**: Converting from Camera Native RGB space to a standard
23//!      connection space (like CIE XYZ) and then to an output space (like sRGB or ProPhoto).
24//!    - See [`color`].
25//!
26//! 4. **Post-Processing & Correction**:
27//!    - **Tone Mapping/Gamma**: Applying gamma curves for display or HDR compression.
28//!    - **Corrections**: Lens distortion, vignetting, and other optical fixes (often handled
29//!      via opcodes in formats like DNG).
30//!    - See [`tonemap`] and [`opcodes`].
