visualize-buffer

generate a visualization of a buffer. for example, to show a public key as a picture.

will generate randomly colored grid.

example

var visualize = require('visualize-buffer')
var random = require('crypto').randomBytes

document.appendChild(visualize(random(32), 256))

visualize(buffer, width) => img

will return a square image, with width. Each nibble (4bits) of buffer is represented as a colored square. If Math.sqrt(buffer.length*2) is a whole number, then the buffer will fit perfectly, otherwise, it will have some blocks shown trailing, and be spaced with white.

If you need to fix that, then make a PR, I only needed this for buffers (ed25519 keys) that fit perfectly in a square.
