SQUIRT (Sequential Unified Image Run Transfer) is a simple image compression algorithm developed by Sandia National Labs. It works with full 32-bit integers to encode 8-bit RGB images by their run lengths, which are stored in the last 8 bits (usually reserved for Transparency). Since most images, even basic images with smooth shading, convert to run-lengths of a single pixel, SQUIRT can also mask out certain color bits to improve compression. These bits typically are not noticeable by the human eye and can significantly reduce the size of the image for transmission. ParaView is, as the name implies, Parallel Aware and offers a great deal of flexibility in how this can be accomplished, and many options to make it work in almost any situation.
