SharpVG

Sharp Vector Graphics

A library and command line utility to convert bitmaps to SVGs.

Why?

• SVG is currently the only reliable way to scale up pixelated graphics with preserving sharpness of the pixels that works across browsers.
• Converting to SVG might be useful in other scenarios, for example when we want to manipulate the image in real time.

Features!

• converts bitmaps to SVGs
• currently supports only one-colour GIFs as input (originally created for my own use)
• fancy edge-tracing algorithm to maximally optimise output size

Examples!

Check out the icons at http://brainshave.com :-) . They're included in this repo and you can generate them by running npm test. (Included only for testing purposes, so please don't use them anywhere.)

Usage (CLI):

sharpvg file.gif > file.svg

Usage (node, simple):

var sharpvg = require("sharpvg")
var svg = sharpvg(fs.readFileSync("file.gif"))

Usage (node, step by step):

var gif = require("sharpvg/gif")
var svg = require("sharpvg/svg")

// raw file buffer:
var raw = fs.readFileSync("file.gif")

// 2-dim array of 1s and 0s:
var bitmap = gif(raw)

// producing svg is a separate step so we can take the bitmap from
// different source
var image = svg(bitmap)

SharpVG also an experiment in writing functional code so it uses Ancient Oak and all in and out data is immutable (apart from file buffers). To get a mutable version, you can use the .dump() method.

Planned features:

• colour support (both indexed and 24-bit)
• PNG input
• animated gif support
