Success!  Through the help of Jeremy Lawrence (jeremy@snrc.uow.edu.au), I've
been able to track down the source of the elusive "XV crashes my OpenWindows
server" bug.

For those of you unacquainted with the problem, suffice it to say that if
you ran XV-2.21 on an 8-bit OpenWindows server, put up an image in the
root window, and then quit XV (leaving the image in the root), the server
would eventually blow up.  As well it should.  I'm surprised this only 
happened to OpenWindows users.

Anyhow, I've put the patch up on export.lcs.mit.edu and ftp.cis.upenn.edu
(the official XV distribution sites), and given how trivial the patch is,
I'll just include it at the end of this message.

If you know of any other anon ftp sites that are distributing XV-2.21, 
*please* do me a favor and put this patch up on them, as well.

Thanks  -  as always, we apologize for the inconvenience.

The following trivial patch fixes the problem with XV-2.21 (when used
to display a root picture and quit) crashing the OpenWindows X server.

Hi,
Is there anyone who can provide some info on what is minimally needed to 
capture video images as a graphic/picture file for the **PC**?

Here's my application.  Our department has recently purchased a high end
Polaroid slide maker (computer graphics to slides at 4,000 lines/inch) 
which makes very nice slides of graphs, graphics, text slides for talks,
symposia, lectures, etc (using Freelance, etc).  

What would be even better is something whereby we could obtain graphic 
pictures of real objects (video camera?) which could be brought up as a 
graphic and then overlaid with text using say, Freelance or another 
equivalent program - then transferred to slide via our slide maker.

This would eliminate the need to make photos, cut & paste them, overlay
text, & re-shoot the text+photo in order to get a slide.  The video capture
would allow people to overlay text on pictures of 3-dimensional objects, 
such as engineering equipment.  I know this could also be done with
scanned images, but this would again involve getting the image on paper
in order to scan it.

Also, what is the available software for this, commercial or public domain?

Thanks in advance,

Greetings.  I can't seem to find any documentation (online or

I have an image I would like to convert from WaveFront into another

For now, all I need is the definition of lines starting with 'v',
'vn', and 'fo'.  Is this something like 'vertex, and 'vertex-normal'??

Thanks in advance.

Organization: VTT/TIK

Has anyone tried to compile Sam Leffler's TIFF package
(tiff-3.0) in MS-DOS?

Several PD programs use this package in Unix machines.
The code also has some defines for MS-DOS. I tried
to compile it using Microsoft C 5.0 and after some
changes I was able to build whole TIFF library. But there
were many warning messages and my test program (tiffinfo)
did not work correctly. It could not recognize all tags and
image dimensions were wrong.

I suspect that problems have something to do with byte ordering
and 16-bit integers.

My MSC 5.0 flags were:

/c /AH /W3 /Zi /Ze /DUSE_PROTOTYPES  /DBSDTYPES /DHAVE_IEEEFP /DINT_16_BIT

Are there any other Tiff packages for MS-DOS (PD/commercial)?

Thanks for reading this!

I am having a problem with John Bradley's XV (v2.21) crashing my xnews
server if I have put any type of image in the root window.  The crash of
the xnews/OpenWindows session does not occur immediately, but usually
within an hour when I do some simple windowing/button click operation.
It will cause a core dump (which file tells me is from xnews) and log me
out... :(  As you could guess, this is determental, to say the least!  I
should say that normal window operations of XV have never seemed to
interfere with xnews.  Just when I use the "-root" switch or by the
interactive window selection mode.

        Does anyone else recognize this problem?  Has anyone any ideas
how I should proceed to debug it?  I've talked with John about it and he
had a suggestion about loosing a call to XFree () in the xvroot.c
routine, but it does not seem to have fixed anything.  I am using SunOS
4.1.2 on a Sun SPARCstation IPC with 36 Mb and OpenWindows3.  I should
note that this seemed to be occuring back when I had OpenWindows2 as
well but I had not related it to XV as of then.  I have also applied the
xnews patch from Sun (#100444-18) as an attempt to fix this problem.  It
did not seem to stop it in any way.

        Any suggestions? Help? Solutions?  Am I the only one who has
ever had this happen...?

Thanks again for taking the time to read through this!

I am running Openwindows 3 and I have a similar problem (as I have reported
a while ago): using xloadimage 3.01 I can load ONE image on the root window.
Then, to load a second one, either I go for a dithered image (B/W) or I
logout and login again. I think something is definitively broken in the root
window handler...

I've a Trident T8900 too, and I didn't notice any additional problems yet.
with VPIC 5.0 . Converting file formats may cause problems (eg. BMPs are
not tested very good, ILBM's are sometimes incorrect displayed.)

!?!?!?! Did you ever use CVPIC to tell VPIC which card to use. Because
        there is NOOO STANDARD for the bank switching of SVGAs, you have
        to tell some programs which banking mechanism to use.

It's funny that the features of WHICHVGA (included in the same ZIP) are
NOT used by VPIC itself.

Hi: 

Has anyone implemented following features extraction routines?.
These features are mentioned in Pratt's Image processing book on page 646.
He has a reference to this which is unpublished Stanford Research Institute'
Notes. Has anyone implemented these or know of any place I can get hold 
of routines which can do following things.


1) The smallest rectangle oriented along the major axis of 
   the object that encompasses the object (Object oriented bounding box)
                                           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2) dimensions of object oriented box, width, height

3) the minimum and maximum distance between the centroid and a 
   perimeter pixel

4) The angle of the minimum and maximum radius vector with respect 
  to the horizontal axis

5) ratio of min radius angle to max radius angle.

Out of the above 1-4 are not difficult to implement but the object
oriented rectangles are the ones i am looking for.

it may be a similar problem to gas particles colliding...

Part of my Honours project is to animate objects and then detect when they
