Claude Code wrote this cpp project from the task below. It does not run on a clean Ubuntu 22.04 machine as written.

Task given to the agent:

TASK: Image Format Converter

Write a program that converts images between common formats (PNG, JPEG, BMP, TIFF, WebP) with configurable quality settings, preserving metadata where possible.

FUNCTIONAL REQUIREMENTS:
- Accept an image file path and target format as command-line arguments
- Support conversions between: PNG, JPEG, BMP, TIFF, and WebP formats
- Support a --quality flag for lossy formats (JPEG, WebP) with a value from 1-100 (default: 85)
- Support a --resize flag to resize during conversion using WxH syntax (e.g., --resize 800x600), preserving aspect ratio by default
- Support --maintain-aspect flag (default true) to control whether resizing preserves the original aspect ratio by fitting within the specified dimensions
- Preserve EXIF metadata during conversion where the target format supports it, with a --strip-metadata flag to optionally remove it
- Support alpha channel handling: when converting from formats with transparency (PNG, WebP) to formats without (JPEG, BMP), use a configurable background color via --background flag (default: white)
- Support batch conversion of all images in a directory via --batch flag, optionally filtering by input format with --filter flag
- Print conversion details to console: input format, output format, original dimensions, new dimensions, file size before and after, compression ratio
- Save the converted image to a path specified by --output flag (default: same name with new extension)
- If no input is given, generate a sample 800x600 PNG image with gradients, text, and transparency, then convert it to all other supported formats and display a comparison table
- Handle errors: unsupported formats, corrupted images, insufficient disk space, invalid resize dimensions

Create a complete C++ project for a clean Ubuntu 22.04 machine with only G++ 12+ and CMake 3.22+ installed. Include:
- Source code
- CMakeLists.txt with all dependencies (direct and transitive) pinned to exact versions
- README.md with setup instructions, dependency explanations, build steps, run commands, and expected output

# Image Format Converter (C++ - FreeImage + nlohmann/json)

An image format converter that supports PNG, JPEG, BMP, TIFF, and WebP formats with quality settings, resize capabilities, and metadata preservation.

## Dependencies

- **FreeImage 3.18.0** - Open source library for image I/O with support for many formats and metadata
- **nlohmann/json 3.11.3** (via FetchContent) - JSON for Modern C++, used for structured output

## Prerequisites

Install FreeImage on your system:

```bash
# Ubuntu/Debian
sudo apt-get install libfreeimage-dev

# macOS
brew install freeimage

# Windows (vcpkg)
vcpkg install freeimage
```

## Build

```bash
mkdir build && cd build
cmake ..
cmake --build .
```

## Usage

### Convert a single image

```bash
./image_converter convert input.png output.jpg
./image_converter convert input.bmp output.webp -q 90
./image_converter convert input.tiff output.png -r 800x600
./image_converter convert input.jpg output.tiff --no-metadata -v
```

### Batch convert images

```bash
./image_converter batch ./input_dir ./output_dir png
./image_converter batch ./photos ./thumbnails jpg -q 75 -r 200x200
```

### Display image information (JSON output)

```bash
./image_converter info photo.jpg
```

## Options

| Option | Description |
|--------|-------------|
| `-q, --quality` | Quality setting (1-100, default: 85) |
| `-r, --resize` | Resize to WIDTHxHEIGHT (e.g., 800x600) |
| `--no-metadata` | Strip metadata from output |
| `-v, --verbose` | Print detailed conversion information |

## Supported Formats

| Format | Read | Write | Notes |
|--------|------|-------|-------|
| PNG | Yes | Yes | Compression level configurable |
| JPEG | Yes | Yes | Quality configurable |
| BMP | Yes | Yes | Uncompressed |
| TIFF | Yes | Yes | LZW compression |
| WebP | Yes | Yes | Quality configurable |
