Disclosed is a low-cost, high-quality system for the taking of orthographic information and bit structuring that information. The system provides a window, which relates aspect ratio of the character in the X, Y plane with the character desired spacing, to operate as the source definition of the X, Y space per character, or pattern. By using an iterating space oriented register and a separate space expansion control in the X direction, redefining and generating a space bit structure related to resolution and size is achieved. The system obviates the problems of holes in characters, memory increases (for line data, font storage, etc.), computational extensions, arithmetic manipulations, and loss of proportional spacing that standard procedures would result in increases in resolution or character size. The system allows control of the aspect ratio manually as well as by program, operation without software intervention or with software interaction. With separate controls, the space oriented register also provides, in the receive mode, an option to store lines of a non-coded data stream for facsimile trans-mission if desired, without adding anything more than a mode control and setting the control to one condition. If the register is used for this purpose, a single switch can control all respective conditions relating to the mode control. In like fashion, the system can accept video data streams from a CRT, for example.
