(machine-readable file or publisher). If publishing, can you give me company
name and phone number (800 numbers are preferred) include manual name , ISBN,

Sorry, but I must very strongly take exception to this.

First of all, I don't know of any serious graphics researchers
(presumably the audience that Siggraph is catering to) who use GIF.
TIFF, on the other hand, is fairly standard.

Secondly (and most importantly), as far as anybody interested in this
type of research is concerned, 256 colors are totally unacceptable, no
matter how well they are quantized and dithered.  Anything less than
24 bits isn't worth the paper it's printed on.  (How's that for mixing
of metaphors?)

Using GIF files with 256 colors may be just fine for trading nude
pictures of Elle MacPherson, but they have no place in graphics
research.  As somebody doing research in rendering and illumination, I
will say that I don't think I could take very seriously a paper in
this area which has images quantized to 256 colors.  JPEG is equally
useless, since it is lossy and therefore will be impossible to
distinguish lossy compression artifacts from rendering artifacts.

Just my opinion.

If you upload a dxf in .zip, I'll probably un-zip it and store it in .Z
(standard Unix compress) format, because dxf's are used by more than just
PC's. I try to leave files in .zip only when they are not going to be
useful to anything other than a PC...

Alex:

"several" isn't the word; "most" I think, is a better description.  As far as
I know, TGS's FIGraph is the closest replacement product for DISSPLA.  We've
made many CA customers very happy; not only because we provide better service 
than CA, but also because we've focused our development efforts on a "faster", 
"smaller", "simpler", and otherwise "better" charting library.

FIGraph is not a one-to-one replacement of the DISSPLA API.  Instead, it
provides equivalent functionallity with much less code.  The big reason 
most FIGraph applications are just 3 lines long, is because we provide a 
"graphics tree" which can be modified from a text file!  So, the ancient 
programming practive of code, compile, link, and execute has been replaced 
with modify text file then execute.  Thus, the time to converge on the chart 
style you want has been decreased dramatically.

FIGraph has both a C and a FORTRAN API and is currently shipping on 
DEC VAX, HP 700, IBM MVS and RS 6000, MIPS, SGI, and SUN.  Porting plans
for DEC ALPHA are in the works.

Martin,

   I don't have any code to do exactly what you mentioned, 
although I am going to be writing some code in C using the ADS 
library to "inflate" some 2D AutoCAD R12 drawings with embedded 
Extended Entity data to 3D models...  Unfortunately I can't share 
the code with you (it is for a client of the company I work for) 
but I will probably be able to answer some of your questions once 
I get started on this (should be yet this month).
   What platform and version of AutoCAD are you developing for?  I 
work primarily with Sun SparcStations and exclusively with Release 
12 of AutoCAD.

This is incorrect. 

ColorView uses the best available image format for saving. If the original 
image was 24 bits, the save JPEG option will write from the original 24 bit 
source, even if an 8 bit quantized version was created for display. 

In fact, ColorView uses the 8 bit image only when absolutely necessary,
eg. for an 8-bit display, or for writing an 8 bit image such as GIF, or 
8 bit BMP. All other processing is pefrformed on the original 24 bit image 
for the highest output quality.

This is the main reason the image saved with ColorView is smaller.

Dithering adds a lot of noise to an image. The file written by WinJPEG is 
bigger because it contains a lot of extraneous dithering information not 
necessary for writing the 24 bit JPEG.

As far as batch conversions of image files, ColorView version 2.1 is in beta 
test and  will be released in a few days. The new features include batch 
conversion from GIF/BMP/JPEG to any of the supported formats. The conversion
utility operates completely in the text mode, and does not require a VGA/SVGA
card, or a VESA driver.

Tom,

I have a request to generate multiple plots per page.  We have software
which can take a multiple page PostScript document and 2-up, 4-up, etc.
print it.  But merely cat'ing together multiple plot files from gnuplot
doesn't work (obviously), since each plot file generated is an independent
plot job.

Do you have (or know of) a program or script which can take cat'ed gnuplot
files and xform the file so that it appears to be a single plot job with
multiple pages, so that I can get multiple plots per page?  Or any other
solution?

I have looked at the .ps files, but am not good enough with PostScript to
figure out what has to be done.

Thanks for any help you can provide.

Ref.: Letter to Alex Woo somewhere round November

Hello,

during the X-mast vacancy I worked round some problems in my GnuPlot
3.1 adds (Splines and Bezier interpolation in data plots and X-errors).
As Alex wanted me to use the already inbuilt contour routines for my
interpolations I had a look at them. Unfortunately the comments in the
code say little more than the function names itself. Do you know who
wrote that routines and could write me the basic stucture and data
types used in there?

Beyond that the source that I should use to add my routines is not
available. To be sure, not even the gnuplot directory seems to
exist at ames.arc.nasa.gov anymore. A friend of mine told me that
he found a gnuplot3.38 beta somewhere in the .sun net. He will
give me copy of that archive in the next days. As I won't have
time to do complicated programming in the next two months, I would
ask you, if there will be any drastic changes in the near future.
Otherwise I would merge my time and would "diff" my code into
your most recent archive, when all is done -- especially because
I now have an MS-DOS programmer set to hunt for my bezier style
bug. Do you have any idea, what could cause a "floating point
error: Domain" on MS-DOS machines only? At least SPARC and Amiga
won't complain.



Aloha, Lars.

There HAS to be a better solution.  Some possiblities:

	   1.  Have "set size" set the actual graph size.
	   2.  Set the default size for all outputs to be the same.
	   3.  Have some way of inquiring the output size so it can
		   be changed inside a script as appropriate.

   Any other ideas?  I like 1 or 3 myself.

When making gnuplot 2.0, we debated a lot about whether the set size
command should use relative scaling factors (as it does now) or
absolute size in inches. The problem is that some devices make more
sense with scale factors (like most terminals) and some devices make
more sense with absolute sizes in inches (like most paper-based
devices, including latex, postscript, and all printers). At the time,
we decided (not unanimously) that more people used terminals than
printers, and to go with the scale factors.

I think we ought to support both forms. Of course, the 'set size'
command cannot be changed now, or we'll break lots of scripts!

Try Gnuplot 3.2. It contains one. But be careful when using it. There is a small
bug which causes nonsense output when printing directly to PRN. Redirect
output to a file and copy it using

copy /b filename PRN

to the printer, that works. (Of course this problem should only
happen under MS-DOS).

All the best, Carsten.

"splot", I get an odd flat surface, and the extents of the plot are all
wrong. If I "set parametric" and replot, the graph looks correct, with
correct extents. The problem is that I need to simultaneously plot a 
non-parametric function. 

It seems to me that the graph I get with noparametric set is incorrect, 
and that this is a bug in gnuplot. Has anyone else had similar 
problems?

Thanks
David
