Thanks for the background info.

triangle fans. The polygons are decomposed into my internal display list
format, where level-of-detail algorithms are used to render the primitive
shapes. The screenshot images are generated directly from tiled frame buffer
images, which are produced by OpenGL typically through some hardware support
from the video card.
The source code for the research version is currently available from my
research group to SRC companies only (since my research was sponsored by
SRC), and by next summer will be available to non-SRC companies as well. My
company is currently working on an improved version of this code, but it may
not be officially released. The source code of the new viewer is part of a
commercial product that is under development and therefore cannot be
released.

Frank,
I can see you are using openGL in a less (ahem...)blunt way than me. I
was just making C functions call from the SREFs, and that is quite
annoying if the end-user needs a compiler to just run the gds viewer.
How did you take advantage of the structures in your viewer ? Using
openGL's display lists ?
(BTW: are you going to put yet what can be opened on sourceforge or
savannah ?)

There are a number of know bugs which may or may not be fixed
eventually,
but it should be able to generate JPEG, RAW, and Windows BMP images of
arbitrary resolution with stipple patterns, even for large GDSII files.

I have a problem creating good printouts from Virtuso's layouts for
documentation porposes.
I want vector graphics output OR high resolution bitmap. The problem
with Cadence is that their printing service produces a horrible
mixture of both.
If you have one of the following outputs set up:
- postscript (1,2): you get the outlines of polygons as a vector
graphic and the fill patterns as low-res bitmaps; unfortunately the
fill patterns are not clipped to their corresponding polygons but
merged with all layers and cut in 'larger squares' afterwards. With
the :residentfonts: option text is preserved as text, but each letter
as a separate object, so you cannot change the size or shape of text
afterwards.
- hpgl: you get only the polygon outlines, no fill patterns;
unfortunately shapes are merged, clipped and stacking orders do no
longer correspond to the drawing layers.
The best way seems to be to export a GDSII stream and use a third
party utility.
So far I tried:
__________
sfviewer 3.5 http://www.nathaniyer.com
Does not preserve colour during export or clipboard-copy. No custom
fill patterns.
__________
GDSII Viewer 1.58b (yuda@akina.ne.jp)
Works fine so far, layer stacking order is messed up though. This
could be fixed in Adobe Illustrator (or similar) afterwards, but is
time consuming.
Perhaps I create a script for that.
I have no URL, but I can send you that program (+source) on request.
__________
SoC GDS Seduction
http://www.dolphin.fr/medal/socgds/socgds_free_overview.html
Does not allow you to print or export graphics.
Do you have any suggestions what else I can try? |

You need to use the cadence supplied raster image generator called
"raptor". Raptor can output cadence layout and schematics directly in
the RTL format.
Raptor is in tools/plot/bin. The examples and samples directory show
how to use it. Here is the interface I use to send rastorized RTL files
directly to HP printers. This worked even sized up to a full 48" plot
and screamed out of the plotter at full plot speed in full color.
Ripped from some web page. Look for references to the RTL format
-------------------
RTL FIles for Large Format Plotters
The plotters have serious issues dealing with large postscript format
files. They are much more reliable and faster reading RTL files
(especially those that are 'Processed in Computer') so plotter users
should arm themselves with the following information resources:
-------------------
-- CDS plotinit --

:manufacturer=Hewelett Packard PCL:\
:type=intCLR:\
:sh:sf:maximumPages#4: \

#!/bin/sh
# MODFIED from tools/plot/samples/cdsBSD.sh
#
# Cadence Design Systems November 1995
#
# This script is used as a filter for the BSD print spooling system. It is
# used to execute the Cadence raptor raster driver. The raptor driver
requires
# command line arguments and a file name to configure itself properly. This
# method of using a script in the place of a print filter allow the user to
# set these arguments and supply a plot file name to the driver for
processing.
#
# The standard mode of operation of the BSD print spooling system is to pass
# the data file as standard input to the filter. The raptor driver requires
# direct access to the file and cannot operate on a stream such as standard
# input. To achieve this we need to gain access to the data file that is
# stored in the print spool directory. This file is owned by the submitter
# of the plot and is not readable by the owner of the print spooling
system.
# It is important that this filter script be owned by "root" and have SUID
# privelages set. Check this by typing "ls -l". The script line should
# look something like the following:
#
# -rwsr-xr-x 1 root sys 0 Nov 21 09:28 cdsBSD.sh
#
# If the line for cdsBSD.sh does not show privelage settings
"-rwsr-xr-x" and
# is not owned by root then login as root and run the following commands:
#
# chown root cdsBSD.sh
# chmod 4755 cdsBSD.sh
#
# You must also edit the path to the raptor driver to point to the Cadence
# software installation path.
#
# When installing the printer use the following printcap entry.
#
# <printer_name>|Cadence Raptor Print Queue: \
# :mx#0:sh:sf:lp=/dev/<plot device>:lf=/usr/adm/lpd-errs: \
# :sd=/usr/spool/<directory>: \
# :if=<install_path>/tools/plot/bin/cdsBSD.sh:

#
# Update the path to include the installation directory for Cadence Software
#
PATH="/bin:/usr/bin:/usr/ucb:/cadence/ic446/tools/plot/bin:"

Hi Dave,
did you mannage to get write skill code for that issue?

StreamVista-Plot is a GDSII viewer that can produce high quality printe
output. A demo version for Windows is available at www.semigy.com.
The software can also export large bitmaps to JPG, PNG, TIFF, BMP, GI
formats

If you use our ps2vector software to batch convert such PS output to
EPS or another vector format (e.g. SVG, WMF, CGM, MIF), it will
automatically merge individual characters into words and words into
one-line text strings in the output - so you can more easily edit the
text and its attributes, while saving filesize. Users of Cadence and
other CAD/EDA systems have used it since 1995 to bring graphics output
into their documentation and publishing systems in scalable and
editable vector formats. Available on Windows, Linux and UNIX
platforms.
You're welcome to send me a sample (E)PS file to give it a try.

We also have a ps2bitmap module to render the PS file to a TIFF, GIF or
JPEG raster image file at any dpi resolution or color depth.

Generating EMF straight from GDI is obviously only possible on Windows.
Have you tried our ps2vector software to convert EPS to EMF? Some
pretty big electronics manufacturers are pretty happy with it, and
chose us over open-source alternatives. Curves stay curves, text stays
text, line styles are preserved, images are preserved, cropping is
preserved. Since it takes (E)PS as input, it can be used in conjunction
with Cadence on any platform.

Something ps2vector can do automatically during conversion. It does
Neat Tricks, developed for users like y'all.
