Module transforms 

Image transformation and processing pipeline.

This module provides the core building blocks for transforming raw sensor data (like Bayer CFA) into viewable RGB images. These transforms are generic and designed to support various RAW formats (ARW, DNG, CR2, NEF, etc.).

General RAW Processing Flow

Most RAW formats follow a similar processing pipeline:

1. Sensor Normalization:

   • Black Level: Subtracting the sensor noise floor (pedestal).
   • White Level: Normalizing signal to a standard range (0.0 - 1.0).
   • See black_level.

2. Demosaicing:

   • Converting incomplete Color Filter Array (CFA) data (e.g., Bayer) into fully populated RGB pixels.
   • See cfa.

3. Color Processing:

   • White Balance: Adjusting gains for Red/Blue channels to neutralize color casts.
   • Color Transformation: Converting from Camera Native RGB space to a standard connection space (like CIE XYZ) and then to an output space (like sRGB or ProPhoto).
   • See color.

4. Post-Processing & Correction:

   • Tone Mapping/Gamma: Applying gamma curves for display or HDR compression.
   • Corrections: Lens distortion, vignetting, and other optical fixes (often handled via opcodes in formats like DNG).
   • See tonemap and opcodes.
