Yes. Start up xprism2, plot a function (e.g. 'x'), then adjust the axes
options & attributes as you like; then use 'HIDE' to remove the graph
from the axes. To better use space, set the axes option 'Plot Legend'
to 'off'. bring up a 'putimage' window with the image that will get the
axes.  Now resize the Xprism2-workspace until the image fits in the
plot area. Select 'Output' in the Xprism2 form and make a screen dump
of the axes workspace. (make shure the workspace is not obstructed when
you hit 'return' in the output pane). This screen dump file can then be
combined with your image by vinsert.  As vinsert doesn't like mapped
files or different number of bands on its inputs, so you will have to
stuff the xprism2 workspace file through vmapdata first. The fastest way
to find the upper left corner for the insert is to bring the screen
dump into putimage and move the mouse to the max of the Y axis. You can
then read the coordinates for vinsert from the bottom of the putimage
window.

This may all sound a bit clumsy and complicated, but once you tried it and
got your axes dump file(s) set up, it's straightforward.

Hello!

	Are there any Toolboxes out there for doing motion analysis?  What I 
want to do is calculate velocity of shedding ice particles.  I have a sequence 
of frames and if I can find the distance, in pixels, from a reference point in 
the frame to the ice particle I can calculate the velocity.  The problem is that
from frame to frame the reference point may not have the same x,y coordinate. 
Selecting the reference point manually may not be quite accurate.  The same 
problem holds for selecting the point on the ice shape.  

	Perhaps it is possible to do this with the routines packaged in Khoros?

Thanks for any light you can shed on this (no pun intended!!)

I run Khoros on a Sun IPC running SunOS 4.1.2 with OPENWIN 3.0.
Xprism3 has never executed without ending with a segmentation fault.  It bombs early in the initialization stage that gives me the suspicion that it is bombing in the initial windowing setup.
I recently acquired the xprism toolbox to attempt to get xprism3 working conclusively.  

This is my first experience compiling anything in the Khoros environment, but I think I have my configuration file's setup properly with the right paths to the appropriate libraries and include directories, but I am getting the following messages: 

cc -o xprism3 form_info.o  form_init.o  main_util.o  persp.o  run_answer.o  run_opts3.o  run_output.o  run_ovlay.o  run_xprism3.o  xp3_main.o  -L/home/oak/ahauter/xprism/lib -L/usr/local/khoros/SparcLib -L/usr/lang/SC1.0  -O -Bstatic   -ldisplay  -lxvplot  -lgraphics  -lxvforms  -lxvutils    -lghost  -lvexpr  -lnum_anal  -ldspl  -lformat  -lgeo_surf  -lvipl  -lvutils  -lvmath  -lvrast  -lvgparm  -lverror  -ltiff    -lm -ll  -lXaw -lXmu -lXt -lXext -lX11

Furthermore, I then executed the make install again and it successfully produced an xprism3 executable, but when executed a segmentation fault occurs.  I  have a list of tricks I'm going to try when I get time, but if anyone has an inclination to what the problem is I would be most gracious.

Subject: colormaps?
Date: 8 Jan 93 23:11:56 GMT
Distribution: comp
Organization: 3M Company, 3M Center, Minnesota, USA

Basically I do not understand how colormaps should/can be used.  For a
single band image is it valid to think of them as a lookup table?
What is used if the colormap is OPTIONAL?  For example the kitten
image distributed with Khoros looks the same on an 8 bit SPARC display
whether I use the colormap or not.   Why?

These questions are driven by my desire to include the histogram of
the image as part of a VIFF image.  One technique which comes to mind is
to incorporate the histogram as a color map but I am not sure what the
effect will be.

I also wanted to use a color map to display the relevant portion of
an image so each of my images would have two (optional) colormaps.

Taking an example of what I want to do.
----------------------------------------------------------------------
My 16 bit image has actual data in the gray level region from pixel
value = 10,000 to 12,000. I can make a color map that linearly
maps this [10K,12K] gray level region to 8 bit data for display.  Do I
lose the original data? Can I do this mapping? Waht data does
EDITIMAGE see - the 8 bit or the 16 bit? What happens if I use
the second map (which must be of type LONG or FLOAT) to store the
histogram? I only want 8 bits of data for the display but the "other"
colormap (which is actually a histogram) must be at least 4 bytes/entry.

Thanks.

Hi Jeff,

The display routines only display (pseudo-colored) images with a colorspace 
model of genericRGB, ntscRGB, or "NONE".  If the image's color space model is 
anything else, you will see each band displayed independently, as you 
described above.  Therefore you need to convert the data before displaying.  
There are a couple conversion routines that convert from the perceptual 
color spaces hls, hsv, to RGB (vcrgbhsv, vcrgbhls).  (They are under 
CONVERSIONS/Color Transform in cantata.)

Inside editimage, you can manipulate the data using other color space 
models, but the initial image still needs to be RGB.

Hi, everybody.

Concerning implicit vs. explicit location data:

I noticed that many routines simply ignore the location information (such as 
dfft1d).  Many other routines will not process files with explicit location
info (such as vextract, and many of the other signal manipulation routines).

1. Are there plans for 2.0 to be more complete regarding location info?

2. Is there a way to strip the location data from a file and make it image 
   data?  How about the other direction (image data -> location data)?

I am also sending this to khoros-bugs but, since it appears 2.0
is a ways off, you may want to change this yourself.

Symptom: If I include viff2xbm as the tail of a pipeline, the
output file has 0 bytes. This does not happen if it is run
by itself.

Probable reason: viff2xbm does not close (fclose) the ascii
output file before exiting.

Cure: the badness went away if I included the line 
fclose(printdev) in viff2xbm.c after the call to lviff2xbm.c

There is template matching algorithm as part of the RLAB toolkit. As

Subject: Problems adding functions to khoros using -O
Organization: 3M Company, 3M Center, Minnesota, USA
Distribution: comp
Date: Tue, 12 Jan 93 17:51:53 GMT

I have been adding some functions to Khoros on a Sparc 2, Sun OS
4.1.2, gcc 2.3.2.  The libraries are compiled shared using cc (even
though sun.cf says to use gcc) e.g.

cc -c -DSHAREDCODE -DSUNSHLIB -O -PIC  -I/usr/khoros/include     -DVFORK -DTEMPNAM -DPUTENV  -DRANDOM   -DWAIT3      lvstats.c
mv lvstats.o shared/lvstats.o

The problem that I have noticed was that my routine compiled with gcc
(or cc) and -O, core dumped, but only when I was not running within a
debugger.  For example, if I compiled using gcc with -O and -g, the
program would run fine from within gdb.  From the command line it
would core dump. (I was using a local copy of lvstats.c to debug the
problem.)  Using gdb to examine the core dump, I got a bus error at
line 730 of lvstats.c - shown below.

      new_stats = stats[i];
->      new_stats->integ = (float)sum;


I could find nothing wrong with sum, i, new_stats,...

One way I resolved the problem was to compile MY top-level function
without -O but I still do not know WHY there even IS a problem.

Very puzzling.  I thought I would simply pass it on.
