A vector images format for the HP plotter, created with the help of the Hewlett-Packard Graphics language. It consists of a set of two-character encoding which determines the allocation of starting points in the plotter. It’s used in various programs for plotting and it’s scalable, maintaining image quality. It has an ASCII structure and is an equivalent to HPG files.
is a format developed for the Shanda Bambook e-books, and is exclusive to those devices. Certain e-books produced by other companies can also view documents of this type. Shanda released its latest device in 2011 which is why this format is not widely used at present.
