| summary |
Applications programs define pictures in a world coordinate system. This can be any Cartesian coordinate system that a user finds convenient. Pictures defined in world coordinates are then mapped by the graphics system into device coordinates. Typically, a graphics package allows a user to specify which area of the picture definition is to be displayed and where it is to be placed on the display device. A single area could be chosen for display, or several areas could be selected. These areas can be placed in separate display locations, or one area can serve as a small insert into a larger area. This transformation process involves operations for translating and scaling selected areas and for deleting picture parts outside the areas. These operations are referred to as windowing and clipping |
