RxAutoIcon Version 2.0 for Windows adds Multi-format Bitmap Support and
Superior Display List Performance to AutoCAD Release 12 for Windows

April 16, 1993 -- Atlanta -- RxAutoIcon Version 2.0 for Windows is a fully
featured ADI 4.2 compatible display list driver for AutoCAD Release 12 for
Windows. Designed to be compatible with any graphics board that is capable
of running Microsoft Windows, RxAutoIcon for Windows will accelerate any
standard display device by bypassing the Windows Graphics Device Interface
(GDI) to reduce graphics bottlenecks inherent within Windows. It is
switchable to use either a 16-bit or 32-bit display list for maximum user
control.

Furthermore, there are a number of intelligent and co-processed graphics
boards that use onboard vector processing chips (e.g. TIGA, S3) to
accelerate the redraw and zoom performance; RxAutoIcon for Windows is
optimized to use each graphics processor to its maximum capability.
Onboard memory is used to store display lists if available, or system
memory is used if it is not.

RxAutoIcon for Windows adds complete bitmap support to AutoCAD Release 12
for Windows. Most popular monochrome and color raster image file formats
are supported (RLC, TIFF, BMP, GIF, DIB, PCX, RLE, TGA). One color or
grayscale bitmap and up to 9 monochrome files can be simultaneously loaded
as a backdrop inside the AutoCAD drawing window. Using a dialogue box
interface, RxAutoIcon for Windows allows the user to create SETS of files
which are stored together for easy matching and retrieval later. Searching
and loading raster files is made much easier by having a quickview window
within the file manager which displays a preview of the raster file or
files before loading.

These raster files can then be scaled simultaneously to match the AutoCAD
scale for accurate reference, dimension measuring, and referencing. A
number of raster editing tools are provided to clean-up the scanned images
for improved image clarity.

Raster file backgrounds are used in a variety of applications: drawing
conversion, mapping, and architectural design, for example. Once the
raster files are loaded, any AutoCAD command can be used to draw over the
images, using them as a reference thereby creating a hybrid raster/vector
file. A powerful feature of RxAutoIcon for Windows is the ability to plot
the resultant hybrid color/grayscale/monochrome file to any supported
Windows output device. The hybrid plotting feature includes an AutoCAD
style plot dialogue box. Plot size, scale, and orientation can be set-up
and even a partial of full preview can be viewed before plotting.

RxAutoIcon Version 2.0 for Windows' ability to significantly accelerate the
standard AutoCAD drawing performance is used to the maximum benefit with a
number of unique display tools. Zooming and panning is performed in
real-time in most accelerated hardware environments--tools include a
magnified cursor with adjustable zoom level, as well as scroll bars for
real-time panning around the whole AutoCAD drawing. A birdseye view of the
entire drawing also allows for real-time drawing update; the view in the
birdseye itself is also user adjustable, depending on existing drawing
limits for maximum clarity.

RASTEREX has developed a whole suite of Windows products for use in the
engineering document management field, known as RxEDM. Adding RxAutoIcon
for Windows to AutoCAD Release 12 for Windows allows it to become part of
a complete document management solution for fast search, retrieve, view,
distribute, redline, convert and plot of most popular engineering
drawings, in both raster and vector formats.

"AutoCAD Release 12 for Windows is the first real Windows CAD program for
the serious draftsperson--its only limitations being bitmap support and
hardware acceleration," says Darrell Knight, president of Expert Graphics,
Inc. "Adding RxAutoIcon for Windows to AutoCAD eliminates those last
remaining issues."

RxAutoIcon Version 2.0 for Windows retails for $195.00 and is available
through Expert Graphics' channel of authorized dealers and VARS. Expert
Graphics Inc. is the sole distributor of RASTEREX graphics products in the
U.S. and Canada.
