bitrot-decay 0.0.9

A lightweight library for simulating digital image decay.

BitRot: Digital Entropy Library

BitRot is a lightweight, zero-dependency Python library designed to simulate digital decay. It intentionally degrades images using bit-crushing, grain injection, and glitch artifacts to simulate file corruption, data rot, and transmission errors.

Unlike standard filters that just add noise, BitRot treats the image as a dying signal, applying structural damage that mimics "bad sectors" and "bit loss" over time.

Use Cases

• Generative Art: Create glitch art or "haunted" digital artifacts.
• Game Development: Simulate damaged data logs, corrupted HUDs, or dying transmissions.
• Data Science: Test machine learning model robustness against noisy or corrupted inputs (adversarial testing).
• Archival Simulation: Visualize the theoretical degradation of digital media over time.

Installation

Install easily via pip:

pip install bitrot-decay

Quick Start

1. File-to-File (CLI Style)

The simplest method. Takes an input file, applies decay based on an integrity score, and saves the result.

import bitrot

# integrity: float between 1.0 (Perfect) and 0.0 (Destroyed)
bitrot.decay_file(
    input_path="assets/photo.jpg",
    output_path="assets/photo_rotted.jpg",
    integrity=0.4
)

2. Memory-to-Memory (API Style)

Ideal for web servers (FastAPI/Flask) or real-time processing where you don't want to save files to disk. Accepts raw bytes and returns raw bytes.

import bitrot

# 1. Load image as bytes
with open("source.jpg", "rb") as f:
    raw_data = f.read()

# 2. Rot the bytes directly
# Returns the raw bytes of the decayed JPEG
corrupted_data = bitrot.decay_bytes(raw_data, integrity=0.15)

# 3. Use the bytes (e.g., send to frontend, save to DB, etc.)
with open("output.jpg", "wb") as f:
    f.write(corrupted_data)

Features & Mechanics

Feature	Description	Trigger Condition
Grain Injection	Simulates sensor noise and film grain.	Active at all decay levels (< 1.0).
Bit Glitching	Randomly shifts pixel blocks to mimic data loss.	Triggers when integrity drops below 0.5.
Chroma Decay	Desaturates colors to simulate fading memory.	Triggers when integrity drops below 0.8.
Safe Clamping	Ensures pixel values stay within valid ranges.	Always Active.
