Hi Everyone,

I've run into an efficiency problem when loading bitmap imagery.
I am looking at fairly large bitmaps (10,000 x 10,000), and when I view
them with putimage there is a very lengthy wait time (over 2 minutes of
CPU time) after the image is read in from disk and before the XImage 
is created.  I have gone through the code and found that the routine 
xvd_build_histogram () computes the histogram for this image, which 
seems to account for the wait and is really unnecessary since there are 
only 2 pixel values in the image by default.
 
So I have made a quick fix that makes the process noticeably faster
when working with large BIT images.  In the file
$KHOROS_HOME/src/xvroutines/Lib/xvdisplay/color.c, lines 216 - 233 
contain the following lines of code:
 
        for (k = 0; k < image->num_data_bands; k++)
        {
           for (j = 0;  j < image->col_size; j++)
           {
           for (i = 0; i < image->row_size; i++)
           {
               if (*data & (1 << (i % 8)))
               histogram[1]++;
               else
               histogram[0]++;
 
               if ((i % 8) == 7)
               data++;
           }
           if ((i % 8) != 0)
              data++;
           }
        }
 
I've simply replaced these with:
 
        histogram [0] = 1 ;
        histogram [1] = 1 ;

Hello Mathew, khorosers,

speaking of Image Restoration, are RLAB or other khoros routines usable for 
improving the quality of images degraded by out-of-focus: for example obtained 
with a video or still camera not foucused correctly (or just because of shallow 
depth-of-field)?

Thanks a lot,

To count holes in an object you could use vlabel but your preprocessing
would have to be good for a reliable hole count particularly if you
require areas etc. Try back lighting it if they are not blind holes. 
This might be improved by running an edge detector first but you
are not guaranteed closure of hole boundaries although there
is an edge closer under the image analysis/segmentation menu of
cantata.

Perhaps a better method would be to run the first stage of a Canny
edge detector ie Gaussian smoothing followed by differentiation
and then extract the enclosed regions with the Grey scale morphology
toolkit or some other gray scale region grower.

It has been awhile since this has come up.  About 9 months ago, we

we did not.  It was implemented poorly.

What prompted us to look at it in detail was that there was a bug on SUNS

decided the best thing to do was leave it alone and rewrite it when we

I have a program which runs fine from command line. I am trying to install
the program so that I can use it as a permenant glyph in cantata. I have
already installed it as a temporary glyph, and that worked fine too. When 
I used kinstall, there were a lot of errors and nothing was installed.

Here is what I did:

kinstall -name vhough -conf vhough.conf -force 1

[Btw, the program is hough transform for line detection which I got 
from  Jean-Pierre Guerin <jpguerin@chouette.saclay.cea.fr> (Thanks
Jean-Pierre)]

Is it possible that other users can use the program without having it 
in khoros main directory? I guess that the errors were due to the fact
that it wasn't able to copy files to KHOROS_HOME. Do I need superuser
previlege for installing a routine in cantata? Could someone send me 
a tutorial for installing a routing in cantata?

Thanks a lot.

You can try the viewimage application in khoros.  It will let you
specify the XYZ data as "elevation coordinates", and the E data as 
image/surface data.  This will give you a 3D plot, with the energy data 
drawn over the plot.  (Display the surface data by selecting the "Surface" 
plot type under the "VIEW UTILITIES/Attributes" button.  Additionally, you 
can associate color maps with both the E data and the Z data.

	James Gallagher, of the  Univ. of Rhode Island's Graduate School

	(I don't have the patch level, it was probably 0 or 1) to 
	a MacII running A/UX 2.0.1, using gcc-1.39 as C compiler.

	As far as I know, James Gallagher is not presently using Khoros,

	He basically recommended using MacX with a UNIX compute engine as a

	From that time, I have his README, his diffs for include files,
	his configuration file, his diffs for source code, and the modifications
	to machdefs and machtype that were needed for the port;  if anyone
	wants to attempt to continue his MacII port, I will be happy to
	send them on request.  However, these will only be useful as a
	starting point -- assuming you want to port Khoros 1.0 Patch5, these
	files will be out of date.

You did not goof - this is a bug.  I easily repeated this here at UNM. 
The fix is to change the file $KHOROS_HOME/src/xvroutines/editimage/roi.h 
and modify the line :

   { " vdiff    ", "vdiff",   "-i1",  "-o", "-i2 ${KHOROS_HOME}/data/kernels/sobel_x -i3 ${KHOROS_HOME}/data/kernels/sobel_y" },

to

   { " vdiff    ", "vdiff",   "-i1",  "-o", "-i2 $KHOROS_HOME/data/kernels/sobel_x -i3 $KHOROS_HOME/data/kernels/sobel_y" },

by removing the '{'s and '}'s, and then recompiling.

I'll forward this to khoros-bugs so it gets properly logged.

Hi all,

I am trying to build a "form fill-in" style interface, for entering a
series of information, such as "first name", "last name", "Birth date",
using string inputs (-s).  Intuitively, I want the keyboard focus to go to
the next box after the user hits return, so they do not have to aim the
mouse cursor for each entry.

I know how to do this with raw Athena widgets, just call XtSetKeyboardFocus() 
with the AsciiText widget as the first argument.  Problem is, how do I get
at the AsciiText widget data structures from within a Khoros application?  

My current convoluted hack involves putting a workspace on the same pane,
doing a XtParent on it to find the form widget, and then cycling through all 
of its children (the form widgets parents of the AsciiText widgets), 
identifying them by the child->core.xrm_name, and setting them to 
global variables for later XtSetKeyboardFocus().

Please tell me there is a better way!

thanks in advance.

The ROI grab bars are not black, but are drawn from a combination
of an inverted line and an xor'd line (i.e. one line drawn with
a function of GXinvert and a line drawn next to it with funcGXxor). 

These gc's (called gc_inv and gc_xor) are initialized in the xvd_initialize 
routine in $KHOROS_HOME/src/xvroutines/Lib/xvdispaly/utils.c.

If you wanted to modify just the way the ROI lines are drawn, that
function is xvd_refresh_roi_bars in $KHOROS_HOME/src/xvroutines/Lib/roi.c 

Hope this helps,

Take a look at load_vector, unload_vector, dload_vector and dunload_vector.
To get information on these routines execute "vman vutils".

A friend of mine has data a file in X Y Z E-value format.  
The E-value is the energy value at X Y Z.
He wants a 3D contour plot of this data.  I had no problem getting
xprism3 to plot a cube of X Y Z values, but thats not what he wants.
I guess this could be consider a 4-dimensional data set.
How do I approach this problem?  Will Khoros do it?  If not,
can anybody recommend anything what will?  
We have DECstations running X-Windows under Ultrix 4.2A.

Please respond to my e-mail address (supah@iastate.edu).  Thank-you!

I would like to obtain a copy of the khoros software. I have a HP 710 and
Vaxstation 3100 and DEC5500 running under Unix.(or ultrix in the case of VAX)
I would appreciate some information as to in which of these environments
khoros works on and how to obtain it.
Thanks

"hi" to all Khoros-Users out there in Net-Land ...
 
we have got our brand new HP DeskJet 500c printer.
we like to produce some color-outputs from Khoros.
i have found a way to do so:

 KHOROS --> viff2pbm --> ppmdither --> ppmtodj --> DeskJet 500c
~~~~~~~~                                          ~~~~~~~~~~~~~~
Does anyone of you know a better way ?
i think the DJ 500c is able to dither colors for itself.
does anyone know how ?
