The current position is the world-coordinate space position at which the next drawing request begins. It is part of the data stored in the presentation space. When you create or obtain a presentation space, the current position is set to the origin (0,0). The current position also is reset to (0,0) whenever a presentation space is associated with a different device context.
Most drawing requests update the current position. If you draw a line from the origin to (3,5), for example, the current position is updated to (3,5). The current position also can be updated explicitly by GpiSetCurrentPosition or GpiMove. If you do not want the first drawing in a presentation space to start at (0,0), call GpiSetCurrentPosition first.
