+/**
+ * @file cli_wrapper.cpp
+ * @brief C++/CLI wrapper exposing the Subvision CV library to .NET
+ * applications.
+ *
+ * Provides managed (.NET) classes that wrap the native C++ API, enabling
+ * C# and other .NET languages to use Subvision CV for impact detection
+ * and sheet coordinate extraction.
+ *
+ * ## Architecture
+ *
+ * The wrapper performs the following marshalling:
+ * - **Input**: Managed `byte[]` arrays (RGBA pixel data) → native `cv::Mat`
+ * (BGR)
+ * - **Output**: Native `subvision::ImpactResults` → managed `ImpactResults^`
+ * with copied image data and managed `Impact^` objects
+ * - **Coordinates**: Managed `List<Point2f^>` ↔ native
+ * `std::vector<cv::Point2f>`
+ *
+ * ## Memory Management
+ *
+ * - Input arrays are pinned (via `pin_ptr`) during processing to prevent GC
+ * relocation
+ * - Output image data is copied from native to managed heap via `Marshal::Copy`
+ * - Native cv::Mat objects are automatically freed when they go out of scope
+ *
+ * ## .NET Usage Example
+ *
+ * ```csharp
+ * using SubvisionNET;
+ *
+ * // Load an image as RGBA byte array
+ * byte[] imageData = LoadImageAsRGBA("target_sheet.jpg", out int width, out int
+ * height);
+ *
+ * // Detect impacts
+ * var results = SubvisionCore.ProcessTargetImage(imageData, width, height,
+ * null); foreach (var impact in results.Impacts)
+ * {
+ *     Console.WriteLine($"Score: {impact.Score}, Distance:
+ * {impact.Distance}mm");
+ * }
+ *
+ * // Get sheet coordinates
+ * var coords = SubvisionCore.GetSheetCoordinates(imageData, width, height);
+ * foreach (var pt in coords)
+ * {
+ *     Console.WriteLine($"Corner: ({pt.X}, {pt.Y})");
+ * }
+ * ```

+# Subvision CV Documentation
+
+Welcome to the **Subvision CV** documentation — the complete reference for the cross-platform computer vision library powering the [Subvision](https://github.com/subvision-soft) underwater target shooting scoring system.
+
+## What is Subvision CV?
+
+Subvision CV is a C++ library that detects, locates, and scores impacts on underwater target shooting sheets. It is used by the Subvision mobile and web application, which aims to be validated by the **FFESSM** (French Underwater Federation) for official competition use.
+
+## Platform Support
+
+Subvision CV runs on three platforms from a single C++ codebase:
+
+| Platform | Technology | Output |
+|----------|-----------|--------|
+| **Native C++** | OpenCV + CMake | Static library (`subvision_lib`) |
+| **WebAssembly** | Emscripten + embind | ES6 module (`subvision_core_es6.js`) |
+| **.NET** | C++/CLI wrapper | Managed DLL (`subvision-x64.dll`) |
+
+## Documentation Sections
+
+- **[Getting Started](manual/getting-started.md)** — Prerequisites, build instructions, and quick start guide
+- **[JavaScript / WebAssembly Guide](manual/javascript.md)** — Complete guide to using Subvision CV in the browser
+- **[Architecture](manual/architecture.md)** — System design, module overview, and data flow
+- **[C++ API Reference](cpp/html/index.html)** — Full Doxygen-generated C++ API documentation
+- **[.NET API Reference](api/)** — DocFX-generated .NET API documentation
+
+## Quick Examples
+
+### C++
+
+```cpp
+#include "subvision_cv.h"
+
+cv::Mat image = cv::imread("target_sheet.jpg");
+subvision::ImpactResults results;
+
+if (subvision::retrieveImpacts(image, results)) {
+    for (const auto& impact : results.impacts) {
+        std::cout << "Score: " << impact.score
+                  << ", Distance: " << impact.distance << "mm"
+                  << std::endl;
+    }
+}
+```
+
+### JavaScript (WebAssembly)
+
+```javascript
+import SubvisionCV from './subvision_core_es6.js';
+
+const module = await SubvisionCV();
+
+const canvas = document.getElementById('targetCanvas');
+const ctx = canvas.getContext('2d');
+const imageData = ctx.getImageData(0, 0, canvas.width, canvas.height);
+
+const results = module.processTargetImage(
+    canvas.width, canvas.height, imageData.data
+);
+
+for (let i = 0; i < results.impacts.size(); i++) {
+    const impact = results.impacts.get(i);
+    console.log(`Score: ${impact.score}, Distance: ${impact.distance}mm`);
+}
+```
+
+### C# (.NET)
+
+```csharp
+using SubvisionNET;
+
+byte[] imageData = LoadImageAsRGBA("target_sheet.jpg", out int w, out int h);
+var results = SubvisionCore.ProcessTargetImage(imageData, w, h, null);
+
+foreach (var impact in results.Impacts)
+{
+    Console.WriteLine($"Score: {impact.Score}, Distance: {impact.Distance}mm");
+}
+```

+# Architecture
+
+This document describes the architecture of Subvision CV, including the module structure, processing pipeline, and cross-platform design.
+
+## System Overview
+
+Subvision CV is a C++ computer vision library built on OpenCV. It processes photographs of underwater target shooting sheets to detect impacts and compute scores.

+
+### Scoring System
+
+The scoring follows FFESSM underwater target shooting rules:
+
+| Distance from Center | Score Formula | Example |
+|---------------------|---------------|---------|
+| > 48 mm | 0 | — |
+| ≤ 0 mm (bullseye) | 570 | 570 |
+| 1–5 mm | 570 − (distance × 6) | 3mm → 552 |
+| > 5 mm | 540 − ((distance − 5) × 3) | 20mm → 495 |
+
+The real-world distance is calculated by mapping the pixel distance between the target center and the impact to the known 45mm target radius.
+
+## Cross-Platform Design
+
+### Colour Space Handling
+
+Each platform provides images in different colour formats:
+
+| Platform | Input Format | Internal Format |
+|----------|-------------|----------------|
+| Native C++ | BGR (OpenCV default) | BGR |
+| WebAssembly | RGBA (browser Canvas) | BGR (converted) |
+| .NET | RGBA (managed bitmap) | BGR (converted) |
+
+All platform bindings convert to BGR before calling the core pipeline. Output images are converted back to RGBA for browser and .NET consumers.
+
+### Memory Management
+
+| Platform | Strategy |
+|----------|----------|
+| Native C++ | Automatic (stack/RAII) — cv::Mat uses reference counting |
+| WebAssembly | Emscripten manages memory; `embind` handles marshalling |
+| .NET | `pin_ptr` for input; `Marshal::Copy` for output; GC handles managed objects |
+
+### Logging
+
+The logging module (`logging.h` / `logging.cpp`) uses compile-time preprocessor directives to select the output mechanism:
+
+| Build Target | Preprocessor | Output |
+|-------------|-------------|--------|
+| Emscripten | `__EMSCRIPTEN__` | `emscripten_log()` → browser console |
+| C++/CLI | `_MANAGED` | `System::Console::WriteLine()` |
+| Native C++ | (default) | `std::cout` |
+
+## Build System
+
+The project uses CMake with platform-specific configurations:
+
+- **Native**: Standard CMake build with `subvision_lib` static library
+- **Emscripten**: Docker-based build with Makefile wrapper
+- **C++/CLI**: MSVC-only build with `/clr` and `/EHa` flags
+
+The `CMakeLists.txt` uses conditional logic (`if(EMSCRIPTEN)`, `if(BUILD_CLI_WRAPPER)`) to configure each target independently.

+# Getting Started
+
+This guide covers prerequisites, building Subvision CV for each platform, and writing your first application.
+
+## Prerequisites
+
+### Common Requirements
+
+- **CMake** 3.27+ ([cmake.org](https://cmake.org/download/))
+- **OpenCV** 4.x with core, imgproc, imgcodecs, features2d, calib3d, dnn modules
+
+### For Native C++ Build
+
+- A C++23-compatible compiler (GCC 13+, Clang 16+, or MSVC 2022)
+- OpenCV 4.x installed and discoverable by CMake
+
+### For WebAssembly Build
+
+- **Docker** ([docker.com](https://www.docker.com/))
+- The build uses the `ghcr.io/subvision-soft/subvision-emscripten:2025.6.1` image which includes Emscripten SDK + OpenCV
+
+### For .NET Build
+
+- **Windows** with Visual Studio 2022
+- **OpenCV 4.x** (`choco install opencv`)
+- **.NET Framework 4.7.2+** or .NET 6+
+
+---
+
+## Building
+
+### Native C++ Library
+
+```bash
+mkdir build && cd build
+cmake ..
+cmake --build . --config Release
+
+# Run tests
+cd test
+./subvision_tests
+```
+
+This produces the static library `subvision_lib` which can be linked into any C++ application.
+
+### WebAssembly (via Docker)
+
+```bash
+# Build both standard and ES6 module versions
+make all
+
+# Or build individually
+make subvision       # Standard version
+make subvision_es6   # ES6 module version
+```
+
+Output files are placed in `build_wasm/`:
+- `subvision_core.js` — Standard WebAssembly wrapper
+- `subvision_core_es6.js` — ES6 module wrapper
+- `subvision_core.wasm` — WebAssembly binary
+
+### .NET Wrapper (Windows)
+
+```bash
+# x64 build
+mkdir build-dotnet-x64 && cd build-dotnet-x64
+cmake -G "Visual Studio 17 2022" -A x64 -DBUILD_CLI_WRAPPER=ON ..
+cmake --build . --config Release
+
+# x86 build
+cd ..
+mkdir build-dotnet-x86 && cd build-dotnet-x86
+cmake -G "Visual Studio 17 2022" -A Win32 -DBUILD_CLI_WRAPPER=ON ..
+cmake --build . --config Release
+```
+
+Output:
+- `build-dotnet-x64/bin/x64/subvision-x64.dll`
+- `build-dotnet-x86/bin/x86/subvision-x86.dll`
+
+---
+
+## Quick Start
+
+### C++ — Detect Impacts
+
+```cpp
+#include "subvision_cv.h"
+#include <iostream>
+
+int main() {
+    // Load an image of a shooting sheet
+    cv::Mat image = cv::imread("target_sheet.jpg");
+    if (image.empty()) {
+        std::cerr << "Failed to load image" << std::endl;
+        return 1;
+    }
+
+    // Enable logging for debugging
+    subvision::setLoggingEnabled(true);
+
+    // Run the full detection pipeline
+    subvision::ImpactResults results;
+    bool success = subvision::retrieveImpacts(image, results);
+
+    if (success) {
+        std::cout << "Detected " << results.impacts.size() << " impacts:" << std::endl;
+        for (const auto& impact : results.impacts) {
+            std::cout << "  Zone: " << impact.zone
+                      << ", Score: " << impact.score
+                      << ", Distance: " << impact.distance << "mm"
+                      << ", Angle: " << impact.angle << "°"
+                      << std::endl;
+        }
+
+        // Save the annotated image
+        cv::imwrite("annotated_result.jpg", results.annotatedImage);
+    } else {
+        std::cerr << "Detection failed" << std::endl;
+    }
+
+    return 0;
+}
+```
+
+### C++ — Two-Step Detection (Manual Sheet Coordinates)
+
+```cpp
+#include "subvision_cv.h"
+
+// Step 1: Detect sheet coordinates (can be stored for reuse)
+cv::Mat image = cv::imread("target_sheet.jpg");
+auto coords = subvision::getSheetCoordinates(image);
+// coords are normalised percentages — resolution-independent
+
+// Step 2: Process with known coordinates (faster, no auto-detection)
+subvision::ImpactResults results;
+subvision::retrieveImpacts(image, results, coords);
+```
+
+### C# — .NET Usage
+
+```csharp
+using SubvisionNET;
+
+// Load image as RGBA byte array (from your imaging library)
+byte[] imageData = LoadImageAsRGBA("target_sheet.jpg", out int width, out int height);
+
+// Optional: enable logging
+SubvisionCore.SetLoggingEnabled(true);
+
+// Detect impacts
+var results = SubvisionCore.ProcessTargetImage(imageData, width, height, null);
+
+if (results != null)
+{
+    Console.WriteLine($"Detected {results.Impacts.Count} impacts:");
+    foreach (var impact in results.Impacts)
+    {
+        Console.WriteLine($"  Zone: {impact.Zone}, Score: {impact.Score}, " +
+                          $"Distance: {impact.Distance}mm");
+    }
+
+    // The annotated image is available as RGBA byte array
+    // results.AnnotatedImageData (Width × Height × 4 bytes)
+}
+```
+

+# Subvision CV Documentation
+
+Welcome to the Subvision CV manual. This documentation covers the complete API and usage guides for the cross-platform computer vision library.
+
+## Overview
+
+**Subvision CV** is a C++ computer vision library for detecting, locating, and scoring impacts on underwater target shooting sheets. It powers the [Subvision](https://github.com/subvision-soft) application used for FFESSM competition scoring.
+
+### Core Capabilities
+
+| Feature | Description |
+|---------|-------------|
+| **Sheet Detection** | Automatically locate the shooting sheet in a photograph |
+| **Target Detection** | Identify the five concentric ring targets on the sheet |
+| **Impact Localisation** | Detect red impact marks (shots) on the targets |
+| **Score Computation** | Calculate scores using FFESSM federation rules (0–570 scale) |
+| **Image Annotation** | Generate annotated images with targets, impacts, and scores drawn |
+
+### Platform Support
+
+The library is deployable on three platforms from a single C++ codebase:
+
+- **Native C++** — Static library linked via CMake
+- **WebAssembly** — ES6 module built with Emscripten for browser usage
+- **.NET** — C++/CLI managed wrapper for Windows desktop apps
+
+### Processing Pipeline
+
+The library follows a sequential pipeline:
+
+1. **Input** — Receive a photograph of a shooting sheet (RGBA or BGR)
+2. **Sheet Detection** — Detect the white sheet boundary and extract corner coordinates
+3. **Perspective Correction** — Warp to a flat 2000×2000 pixel image
+4. **Target Detection** — Locate the elliptical target rings in each of the 5 zones
+5. **Impact Detection** — Find red impact marks via colour analysis
+6. **Scoring** — Compute distance and score for each impact
+7. **Annotation** — Draw targets, impacts, lines, and scores on the image
+8. **Output** — Return the annotated image and list of scored impacts
+

+# JavaScript / WebAssembly Usage Guide
+
+This guide covers how to use Subvision CV in web applications via the Emscripten WebAssembly module.
+
+## Overview
+
+Subvision CV is compiled to WebAssembly using Emscripten and exposed to JavaScript through `embind`. The module provides two main functions:
+
+| Function | Purpose |
+|----------|---------|
+| `processTargetImage(width, height, data)` | Detect and score all impacts on a shooting sheet |
+| `getSheetCoordinates(width, height, data)` | Detect the sheet corner coordinates |
+| `setLoggingEnabled(bool)` | Enable/disable console logging |
+
+## Loading the Module
+
+### ES6 Module (Recommended)
+
+```javascript
+import SubvisionCV from './subvision_core_es6.js';
+
+// Initialize the module (loads the WASM binary)
+const module = await SubvisionCV();
+console.log('Subvision CV loaded successfully');
+```
+
+### Standard Script
+
+```html
+<script src="subvision_core.js"></script>
+<script>
+    Subvision().then(module => {
+        console.log('Subvision CV loaded successfully');
+    });
+</script>
+```
+
+## Core API
+
+### Processing a Target Image
+
+The `processTargetImage` function takes raw pixel data from a canvas and returns impact detection results.
+
+```javascript
+async function processImage(imageElement) {
+    const module = await SubvisionCV();
+
+    // Draw image to a canvas to get pixel data
+    const canvas = document.createElement('canvas');
+    canvas.width = imageElement.naturalWidth;
+    canvas.height = imageElement.naturalHeight;
+    const ctx = canvas.getContext('2d');
+    ctx.drawImage(imageElement, 0, 0);
+
+    // Get RGBA pixel data
+    const imageData = ctx.getImageData(0, 0, canvas.width, canvas.height);
+
+    // Process the image
+    const results = module.processTargetImage(
+        canvas.width, canvas.height, imageData.data
+    );
+
+    // Read results
+    console.log('Annotated image dimensions:',
+        results.annotatedImage.rows, 'x', results.annotatedImage.columns);
+
+    const impactCount = results.impacts.size();
+    console.log(`Detected ${impactCount} impacts:`);
+
+    for (let i = 0; i < impactCount; i++) {
+        const impact = results.impacts.get(i);
+        console.log(`  Impact ${i + 1}:`,
+            `score=${impact.score}`,
+            `distance=${impact.distance}mm`,
+            `zone=${impact.zone}`,
+            `angle=${impact.angle}°`
+        );
+    }
+
+    return results;
+}
+```
+
+### Displaying the Annotated Image
+
+```javascript
+function displayAnnotatedImage(results, targetCanvas) {
+    const mat = results.annotatedImage;
+    const width = mat.columns;
+    const height = mat.rows;
+
+    targetCanvas.width = width;
+    targetCanvas.height = height;
+    const ctx = targetCanvas.getContext('2d');
+
+    // Get pixel data from the Mat (RGBA format)
+    const data = new Uint8ClampedArray(mat.data);
+    const imageData = new ImageData(data, width, height);
+
+    ctx.putImageData(imageData, 0, 0);
+}
+```
+
+### Detecting Sheet Coordinates
+
+Use `getSheetCoordinates` to find the sheet corners. These can be cached and reused.
+
+```javascript
+async function detectSheet(imageElement) {
+    const module = await SubvisionCV();
+
+    const canvas = document.createElement('canvas');
+    canvas.width = imageElement.naturalWidth;
+    canvas.height = imageElement.naturalHeight;
+    const ctx = canvas.getContext('2d');
+    ctx.drawImage(imageElement, 0, 0);
+
+    const imageData = ctx.getImageData(0, 0, canvas.width, canvas.height);
+
+    // Returns an array of {x, y} points (normalised 0-1 coordinates)
+    const coords = module.getSheetCoordinates(
+        canvas.width, canvas.height, imageData.data
+    );
+
+    console.log('Sheet corners:');
+    for (let i = 0; i < coords.length; i++) {
+        console.log(`  Corner ${i}: (${coords[i].x}, ${coords[i].y})`);
+    }
+
+    return coords;
+}
+```
+
+## Data Types
+
+### Impact Object
+
+| Property | Type | Description |
+|----------|------|-------------|
+| `distance` | `number` | Distance from target center (mm) |
+| `score` | `number` | Score on 0–570 FFESSM scale |
+| `zone` | `number` | Target zone ID (0–4, or -1) |
+| `angle` | `number` | Angular position in degrees |
+| `count` | `number` | Impact count (usually 1) |
+
+### ImpactResults Object
+
+| Property | Type | Description |
+|----------|------|-------------|
+| `annotatedImage` | `Mat` | Annotated image with drawn targets and scores |
+| `impacts` | `ImpactVector` | Vector of Impact objects |
+
+### Mat Object
+
+| Property | Type | Description |
+|----------|------|-------------|
+| `rows` | `number` | Image height in pixels |
+| `columns` | `number` | Image width in pixels |
+| `data` | `Uint8Array` | Raw RGBA pixel data |
+
+### ImpactVector Methods
+
+| Method | Returns | Description |
+|--------|---------|-------------|
+| `.size()` | `number` | Number of impacts |
+| `.get(index)` | `Impact` | Impact at the given index |
+
+## Performance Considerations
+
+- **Image size**: Larger images take longer. The library internally resizes to 2000×2000 pixels, so there is no benefit to providing images larger than this.
+- **First call**: The first call may be slower due to WASM compilation. Subsequent calls are faster.
+- **Memory**: Use `Module._malloc` and `Module._free` carefully if working with raw memory. The embind API handles memory automatically for the exported functions.
+- **Web Workers**: For non-blocking UI, run the processing in a Web Worker.
+
+## Error Handling
+
+```javascript
+try {
+    const results = module.processTargetImage(width, height, data);
+    if (results.impacts.size() === 0) {
+        console.warn('No impacts detected — the sheet may not be visible');
+    }
+} catch (error) {
+    console.error('Processing failed:', error.message);
+    // Common causes:
+    // - Image does not contain a visible shooting sheet
+    // - Image is too dark or overexposed
+    // - Sheet is partially occluded
+}
+```
+
+## Debugging
+
+Enable logging to see the internal processing steps in the browser console:
+
+```javascript
+module.setLoggingEnabled(true);
+
+// Process image — detailed logs will appear in the console
+const results = module.processTargetImage(width, height, data);
+
+// Disable logging when done
+module.setLoggingEnabled(false);
+```

+/**
+ * @file emscripten_binding.cpp
+ * @brief WebAssembly bindings for the Subvision CV library via Emscripten.
+ *
+ * Exposes the core Subvision functionality to JavaScript through Emscripten's
+ * embind system. This file handles:
+ * - RGBA → BGR colour space conversion (browser images are RGBA)
+ * - Typed array marshalling between JavaScript and C++
+ * - Result packaging as JavaScript-friendly objects
+ *
+ * ## Exported JavaScript API
+ *
+ * | C++ Function            | JavaScript Function                    |
+ * Description                           |
+ * |-------------------------|----------------------------------------|---------------------------------------|
+ * | `processTargetImage<T>` | `Module.processTargetImage(w, h, arr)` | Detect
+ * and score all impacts          | | `getSheetCoordinates<T>`|
+ * `Module.getSheetCoordinates(w, h, arr)`| Detect sheet corner coordinates | |
+ * `setLoggingEnabled`     | `Module.setLoggingEnabled(bool)`       |
+ * Enable/disable console logging        |
+ *
+ * ## JavaScript Usage Example
+ *
+ * @code{.js}
+ * import SubvisionCV from './subvision_core_es6.js';
+ *
+ * const module = await SubvisionCV();
+ *
+ * // Get image data from a canvas
+ * const canvas = document.getElementById('myCanvas');
+ * const ctx = canvas.getContext('2d');
+ * const imageData = ctx.getImageData(0, 0, canvas.width, canvas.height);
+ *
+ * // Process the target image
+ * const results = module.processTargetImage(canvas.width, canvas.height,
+ * imageData.data); console.log('Number of impacts:', results.impacts.size());
+ *
+ * for (let i = 0; i < results.impacts.size(); i++) {
+ *     const impact = results.impacts.get(i);
+ *     console.log(`Impact: score=${impact.score},
+ * distance=${impact.distance}`);
+ * }
+ *
+ * // Get sheet coordinates
+ * const coords = module.getSheetCoordinates(canvas.width, canvas.height,
+ * imageData.data); for (let i = 0; i < coords.size(); i++) { const pt =
+ * coords.get(i); console.log(`Corner: (${pt.x}, ${pt.y})`);
