Very fast image processing library with low memory use

About

• More than 300 image processing functions
• Language bindings for C, Ruby, Python, PHP, C#, Go, Lua
• There are also a CLI and libraries for Node and RoR.

In most cases much faster and uses less memory than libraries such as ImageMagic/OpenCV/etc.

Why libvips is fast

• https://github.com/libvips/libvips/wiki/Why-is-libvips-quick
• Instead of processing the whole image in memory, processes only parts of the image in memory, streamed on demand.
• Developed to use fast operations
• Handles image IO with threading
• Supports parallel processing
• Region-based processing (overlap allowed) rather than tile-based processing (split without overlap)
• Uses almost no locks.
• Supports 10 pixel formats from 8-bit to 128-bit
