LibPixel is a realtime image manipulation service for any images that are available on the internet.
LibPixel works by fetching images from an existing Image Source, processing them on the fly and responding with the modified image. You simply supply the image size or processing you want in the query string in the URL you use for the image (perhaps in an IMG tag), and LibPixel does the rest. LibPixel is designed to be fast. It is likely that the transit/download time will be far more significant than the time taken by LibPixel to process the image, so in practice processed images are delivered as fast or faster (due to caching and CDN) than the original image.
