Image quality
RGS provides high-quality, high-performance image compression and decompression. Image
compression is performed on the remote computer to reduce the network bandwidth requirements—
this enables RGS to be used on standard networks. Image decompression is performed on the local
computer.
Image quality is adjusted using the slide bar in the Remote Display Window toolbar (see
Figure 5-20
Image quality slide bar in the Remote Display Window toolbar on page 54). As the image quality is
increased toward 100, the amount of compression decreases, and the required network bandwidth
increases. If a Receiver is supporting multiple Remote Display Windows (see
Many-to-one
connection on page 10) the slide bar in any Remote Display Window toolbar can be adjusted—the
slide bars in the other Remote Display Windows will automatically track.

NOTE: Even with an image quality of 100, RGS still performs some image compression to reduce
the network bandwidth requirements. While the image quality on the Receiver will usually appear
visually lossless to the user, the actual image data sent over the network will be “lossy” to a limited
extent. The exception is the Sender codec JPEG-LS which is mathematically lossless. See
Sender
general properties on page 137 for more information.
