Data Compression Analyzer

A GUI application for analyzing and comparing compression algorithms, built with Dear ImGui and C++17.

---

Features

• Support for multiple compression algorithms:
  • Gzip (with configurable compression levels)
  • Archive+Gzip (for compressing multiple files into a single archive)
• Modern GUI built with Dear ImGui
• Comprehensive performance metrics:
  • Compression ratio
  • Compression time
  • Decompression time
  • Memory usage
  • Entropy
  • Throughput
• Multi-file selection and processing
• Export results in CSV or JSON format
• Cross-platform support (Windows, macOS, Linux)

Requirements

• C++17 or later
• CMake 3.15 or later
• Required libraries (auto-fetched or installed via your package manager):
  • Dear ImGui (auto-fetched)
  • tinyfiledialogs (auto-fetched)
  • nlohmann-json (auto-fetched)
  • zlib (for Gzip compression)
  • GLFW3
  • OpenGL

macOS (Homebrew) example:

brew install cmake zlib glfw nlohmann-json

Building and Running

Clone the repository and then build and run the application:

# Clone the repository
git clone https://github.com/Karan5352/data-compression-analyzer.git
cd data-compression-analyzer

# Build and run (from the project root)
rm -rf build && mkdir build && cd build && cmake .. && make && ./DataCompressionAnalyzer

Usage

1. Launch the application
2. Click "Open Files" to select one or more files for analysis
3. Choose the compression algorithm:
   • Gzip: Compresses individual files
   • Archive+Gzip: Compresses multiple files into a single archive
4. Adjust compression level (1-9) for both algorithms
5. Click "Start Analysis" to begin compression
6. View results in the interactive interface:
   • Summary statistics
   • Detailed results table
7. Export results in CSV or JSON format

Features in Detail

Gzip Compression

• Configurable compression levels (1-9)
• Individual file compression
• Detailed performance metrics (ratio, time, entropy, throughput)

Archive+Gzip Compression

• Combines multiple files into a single archive
• Uses Gzip compression internally
• Preserves file structure and names
• Configurable compression levels

Results Analysis

• Compression ratio calculation
• Compression and decompression timing
• Memory usage tracking
• Entropy calculation
• Throughput calculation
• Export functionality for further analysis
