## The contenders
* [jimp](https://www.npmjs.com/package/jimp) v0.16.1 - Image processing in pure JavaScript. Provides bicubic interpolation.
* [mapnik](https://www.npmjs.org/package/mapnik) v4.5.5 - Whilst primarily a map renderer, Mapnik contains bitmap image utilities.
* [mapnik](https://www.npmjs.org/package/mapnik) v4.5.6 - Whilst primarily a map renderer, Mapnik contains bitmap image utilities.
* [imagemagick](https://www.npmjs.com/package/imagemagick) v0.1.3 - Supports filesystem only and "*has been unmaintained for a long time*".
* [gm](https://www.npmjs.com/package/gm) v1.23.1 - Fully featured wrapper around GraphicsMagick's `gm` command line utility.
* sharp v0.27.0 / libvips v8.10.5 - Caching within libvips disabled to ensure a fair comparison.
* sharp v0.28.0 / libvips v8.10.6 - Caching within libvips disabled to ensure a fair comparison.

Greater libvips performance can be expected with caching enabled (default)
and using 4+ core machines, especially those with larger L1/L2 CPU caches.
and using 8+ core machines, especially those with larger L1/L2 CPU caches.
The I/O limits of the relevant (de)compression library will generally determine maximum throughput.
