I contacted Xing Tech about a week and a half ago asking for some
information on their JPEG related products.  Here is what they provided me
with.  Next message contains info on their fast JPEG viewer for DOS and
Windows.  I have copied the text verbatim.

VT COMPRESS -- Info sheet

VT COMPRESS   Jpeg Image Compression Software for 80386/486 PC's
              Product Description

What is VT-COMPRESS?

VT-COMPRESS is a JPEG-compatible image compression software package
which is optimized for 80386/486-based PC's and compatibles running
DOS or WINDOWS.  VT-COMPRESS can quickly compress grey-scale and
full-color images by as much as 100:1, though compression ratios of
8:1 to 20:1 are more typically used.

What is JPEG?

JPEG (Joint Photographic Experts Group) is an international group of
image compression experts formed in 1986 by ISO and CCITT to
develop techniques for the removal of redundant information from
grey-scale and full-color images, for the purpose of reducing image
storage requirements and transmission times.  The JPEG Baseline
Algorithm, to which VT-COMPRESS conforms, is the final process of
adoption as an international standard.

Why Would I use VT-COMPRESS?

If you currently use software which captures, stores, manipulates
or transmits grey-scale or full-color images in, for example,
multimedia databases, desktop publishing, presentation graphics,
medical imaging, or remote picture transmission, you are probably
aware of the huge disk storage requirements or transmission times
of individual images - a single 512x512 pixel resolution color
image requires over 750 kbytes storage space.  VT-COMPRESS is able
to quickly reduce the size of such an image by a factor of 20 or
more (i.e. to less than 35 kbytes), while still maintaining the
quality of the original image.

On What Systems Can VT-COMPRESS run?

VT-COMPRESS can be run on any 80386/486-based IBM PC, PS/2, or
compatible, running DOS or Windows version 3.x.  VT-COMPRESS
requires no special hardware or math co-processor.  The software
requires less than 350 kbytes disk storage and 1Mbyte RAM.

How Fast is VT-COMPRESS?

VT-COMPRESS performance was specially optimized for the Intel
80386/486 processors.  VT-COMPRESS will reduce a 512x512x24 bit RGB
TARGA or TIFF file (approx. 786,432 bytes) to a 35 kbyte JPEG file
in under 6 seconds on a 33-mhz 386.  Conversion of the JPEG file
back to TARGA or TIFF format takes the same amount of time, though
the VT-EXPRESS software accelerator is available to reduce this
time to as little as 1 second.

What Does VT-COMPRESS cost?

VT-COMPRESS for DOS and Windows costs $179.  The VT-EXPRESS JPEG
accelerator costs $249 extra, though a bundled price of VT-COMPRESS
with VT-EXPRESS is $349.
