Fast gaussian blur in pure JavaScript via IIR filer

glur

Fast Gaussian Blur in pure JavaScript, via IIR filer. Speed does not depend on blur radius.

demo 1, demo 2.

Install

npm install glur --save

API

require('glur')(src, width, height, radius)

• src - typed array with image RGBA data (will be updated with blured image).
• width - image width.
• height - image height.
• radius - blur radius.

require('glur/mono16')(src, width, height, radius) - the same as above, but input data is grayscale Uint16Array. Can be useful to calculate unsharp mask via brightness/ligthness channel.
