Show HN: FastResize – A Fast Image Resizer Supporting Batch Processing

I'd like to share FastResize (https://github.com/tranhuucanh/fast_resize https://github.com/tranhuucanh/fast_resize), a high-performance image resizing library written in C++. This is my second open-source project after FastQR, and I'm excited to share it with you all. What it is: - A fast CLI tool and Ruby gem for resizing images - Written in C++ with Ruby bindings - Supports batch processing for handling thousands of images efficiently - Pre-built binaries included – no need to install dependencies separately - Available as a Ruby gem on RubyGems: https://rubygems.org/gems/fast_resize https://rubygems.org/gems/fast_resize Why I built this: - I needed an image resizer that was fast, memory-efficient, and could handle batch processing easily. Most existing solutions were either slow or consumed too much memory when processing large batches. Performance: - Resizing 1,000 images: ~2 seconds - Up to 2.9x faster than libvips - Up to 3.1x faster than imageflow - Uses 3-4x less RAM than alternatives Tech stack: - C++ core using optimized image processing libraries - Ruby gem for easy integration - Precompiled binaries for CLI usage Installation: - Ruby gem: `gem install fast_resize` or add `gem 'fast_resize'` to your Gemfile - CLI: Please check from GitHub repository: https://github.com/tranhuucanh/fast_resize https://github.com/tranhuucanh/fast_resize This is my second open-source project, so I'm sure there are things that could be improved or bugs I haven't caught yet. I'd really appreciate it if you could try it out and share your feedback. If you find any issues or have suggestions, please open an issue on GitHub – I'll do my best to fix them quickly. Any feedback, criticism, or suggestions would be greatly appreciated. Thanks for taking the time to check it out!
