RGS overview 22
NOTE: For clarity in this guide, the bitmapped image contained in the Remote Computer frame buffer will often
be shown in association with the Remote Computer, independent of whether a monitor is actually connected
(or can be connected) to the Remote Computer.
2-8-2 One-to-one connection
The simplest RGS connection is a single Local Computer making a connection to a single Remote Computer. The
entire frame buffer of the Remote Computer is displayed in a window on the Local Computer (see Figure 2-6). The
window on the Local Computer is called the Remote Display Window.
Figure 2-6 Display of the Remote Computer frame buffer on the Local Computer
In Figure 2-6, the Remote Computer frame buffer fits completely within the Remote Display Window on the Local
Computer monitor. However, it is possible for the Remote Computer frame buffer size to exceed the size of the
Local Computer monitor (as measured in horizontal pixels by vertical pixels). As before, the Remote Display
Window will be the size of the Remote Computer frame buffer. If the Remote Display Window is larger than the
Local Computer monitor, the window will extend off the monitor.
Regardless of the size of the Remote Display Window (that is, whether it fits on the Local Computer monitor or
extends off the monitor), if the local user resizes the Remote Display Window to be smaller than when it was
originally created, scroll bars will be added to allow the local user to view the complete Remote Computer frame
buffer (see Figure 2-7).
Figure 2-7 Addition of scroll bars if the Remote Display Window is resized smaller
NOTE: RGS does not provide a scale-to-fit capability to allow the contents of the Remote Computer frame buffer to be
scaled to fit the Local Computer monitor. If the Remote Computer frame buffer is larger than the Local Computer monitor,
the Remote Display Window will simply extend beyond the edges of the monitor. If the Remote Display Window is resized
to fit on the monitor, scroll bars will be added.
