build_test scrimage core v scrimage @ kotlinlang.slack.com

Scrimage is an immutable, functional, and performant JVM library for manipulation of images.

The aim of this library is to provide a simple and concise way to do common image operations, such as creating thumbnails, converting between image formats, resizing to fit a required width and height, applying filters, cropping, and so on.

It is easy to use from any language on the JVM.
