Sounds good. Can whip that up. May be a week or two.

Here's a work around for how to do "cover" with the current features:

In the following code, options.width and options.height contain the final size.

new Jimp(input, function(error, image) {
  if(error) throw error;
  // Crop image to same ratio as output
  var ratio  = Math.min(
    image.bitmap.width / options.width,
    image.bitmap.height / options.height);
  var offsetX = (image.bitmap.width - (options.width * ratio)) / 2;
  var offsetY = (image.bitmap.height - (options.height * ratio)) / 2;  
  image.crop(offsetX, offsetY,
    image.bitmap.width - (offsetX * 2),
    image.bitmap.height - (offsetY * 2)
  );
  image.resize(options.width, options.height);

  // image is now covering the new dimensions
});

I'm not 100% sure but I would think "contain" would simply be a matter of switching Math.min with Math.max.

Done. Added image.cover(w, h) and image.contain(w, h). Thanks for the suggestion.
