please open an issue if you have the answer. i'm sure it works, i just don't have ready the exact commands.

Usage

# Require library
gd = require 'node-gd'

# Create blank new image in memory
output_img = gd.create width, height

# Load existing image file on disk into memory
gd.openPng "test.png", (err, input_img) ->
  console.log "width: ", input_img.width
  console.log "height: ", input_img.width

# Render input over the top of output
input_img.copyResampled output_img, dstX, dstY, srcX, srcY, dstW, dstH, srcW, srcH

# Write image buffer to disk
output_img.savePng "out.png", 0, (err) ->
  console.log "image saved!"

As usual, for the latest examples, review the easy-to-follow ./test/test.coffee.
