lut

README

LUT contains command-line tools and Go packages for applying colour adjustments to images using lookup tables.

Motivation and caveats

I wrote this command-line tool and package to inspect LUT's locally, and provide basic server-side rendering. This is most likely a bad idea, and you should probably be doing colour manipulations in OpenGL or a similar graphics programming framework.

Example

go run main.go apply testdata/sample.jpg --lut testdata/filter.png --out testdata/output.jpg
