A pure Ruby library for reading and writing PNG images with full support for all color modes, bit depths, transparency, and interlacing. It provides pixel-level and metadata access without requiring native image libraries like RMagick.
Use cases
- read and write png files in ruby
- manipulate png pixels programmatically
- compose images with alpha blending
- read png metadata chunks
- generate png images from scratch without imagemagick
When to choose
- you need PNG support in Ruby without native C dependencies
- portability across Ruby versions and platforms matters
- you need fine-grained pixel or chunk-level access
When to avoid
- you need high performance image processing (consider OilyPNG or RMagick)
- you need formats other than PNG
- processing untrusted images - it is vulnerable to decompression bomb DoS attacks
