Wrapper around optipng-bin for use with stdin/stdout


Issues with the output should be reported on the image-min issue tracker.

This is a wrapper around node-optipng-bin to add support for reading input PNG data from STDIN and writing the generated output PNG data to STDOUT. The module is intended to be used only as a binary in the same style as modules that use bin-wrapper. It cannot be used in any other fashion.

var fs = require('fs');
var optipng = require('optipng-stream-bin').path;
var spawn = require('child_process').spawn;
var cp = spawn(optipng, ['-o2']);
var read = fs.createReadStream('test.png');
var write = fs.createWriteStream('test-optimized.png');
