    PNG Crop

    Small PNG crop utility, written in pure JS for Node.

    npm install png-crop

    Usage

    (Check out the example folder.)

    Both methods take a image path/stream/buffer as input, and a configuration with the keys width, height (mandatory, can be arbitrarily large) and top and left (optional).

    Crop and output to file

    var PNGCrop = require('png-crop');
     
    // if you don't know the image's dimension and want to crop for a point all the
    // way til bottom right, just pass a big width/height
    var config1 = {width: 100, height: 62, top: 95, left: 110};
    // pass a path, a buffer or a stream as the input
    PNGCrop.crop('1.png', 'expectedCropTopLeftConfig.png', config1, function(err) {
      if (err) throw err;
      console.log('done!');
    });

    Crop and get the output stream

    var PNGCrop = require('png-crop');
     
    // optionally pass top and left to the configurations as the upper left corner
    // from which to start cropping
    var config2 = {width: 53, height: 114};
     
    var imgBuffer = fs.readFileSync('1.png');
    PNGCrop.cropToStream(imgBuffer, config2, function(err, outputStream) {
      if (err) throw err;
      outputStream.pipe(fs.createWriteStream('expectedCrop.png'));
    });
