Defines those functions of the Computer Graphics Interface concerned with the creation, modification, and manipulation of graphic pictures using segments.

This part of ISO/IEC 9636 defines those functions of the Computer Graphics Interface concerned with the creation, modification, and manipulation of graphic pictures using segments.

This part of ISO/IEC 9636 is part 4 of ISO/IEC 9636, and should be read in conjunction with ISO/IEC 9636-1, ISO/IEC 9636-2, and ISO/IEC 9636-3. The relationship of this part of ISO/IEC 9636 to the other parts of ISO/IEC 9636 is described in ISO/IEC 9636-1 and in clause 4.

The functionality described in this part of ISO/IEC 9636 pertains to Virtual Devices of class OUTPUT and OUTIN.
