What?
A few lines that takes a readable stream of PNGs, splits it, and emits "image" events
How?
var myReadablePngStream = ...var PngSplitter = require("png-splitter")var pngSplitter = new PngSpliter(myReadablePngStream) pngSplitter.on("image", function(image) {})
Notes
This relies on stream.pipe, so make sure your stream implementation properly implements back-pressure and what not!
