When I try to analyze a jpeg image, it counts the objects =satisfactorilybut when I tryto do an Object Analysis the program crashes with the following message:        IT caused an exception 10H in module UTILIB31.DLL at                0137:006d345bOnce this error is cleared and I quit the program I get the error:        IT caused an exception C0000026H in Module KERNEL32.DLL at                0137:bffb87c0Any idea why this is occuring?Hello,Unfortunately, I have only a vague idea why the first is occurring.  The =second is a direct result of the first, and will be eliminated when I =fix the first.  This is a general request to anyone who has seen this =problem:  if you could send me, via email, the image file that you are =analyzing when the system crashes, I will make every attempt to track it =down and fix it.Another approach that may prove helpful is to turn off the Object =Analysis options (from the ImageTool settings sheet), and turn them on =one-at-a-time to determine which calculation is causing the crash.  It =is possible that if I knew which function was crashing, I could fix the =problem without an example image.Thanks for your help,Don------------------------------Date: Fri, 26 Jan 1996 06:52:14 -0700From: Don Wilcox To: 'ImageTool List Server' Subject: RE: Zoom/Scroll BugMessage-ID: <01BAEBBA.F41262C0@slip2.xroads.com>----------From:  Squiers[SMTP:maddog@gateway.cybernet.com]Sent:  Wednesday, January 24, 1996 07:42 PMTo:  wilcox@xroads.comSubject:  Zoom/Scroll BugI have attempted to use IT for manually picking pixels out of images.  I =amusing v 1.1 and the "Points" tools.  The only time the pixel positions =arerecorded correctly in the "Results" window, is when the image is neithermagnified nor scrolls (i.e., 100% of the image doesn't fit in the =window).The pixel position is being reported correctly on the status line, it's =justnot recorded in a useful manner :)You are correct (oops).  This will only occur when the left or top edge =of the image window is not exactly aligned on a pixel.  So of course, it =doesn't show up in an unzoomed window, and in a remarkable coincidence, =did not show up in the images I use to test these features (a new image =has been added to the test suite to compensate).  Anyways, I have made =note of the problem, and it will be addressed in the next release of IT, =currently scheduled for the end of February, although another bug fix =patch is not out of the question.BTW: This is a wonderful program...it's been helpful in making the =difficulttransition from Mac to PC...I truly am glad you like it.

Itallows you to specify the byte offset of the data, along with the size(width, height, bit depth) of the data itself.  If your images are 8 bitgray scale or 24 bit color, then this should work for you.  Simply make surethat the file ~binfltr.dll is in the "File Filters" directory (if not, youcan download it from maxrad6), and then select the image files from the opendialog box.  You will be presented with a dialog in which you can specifythe image information.  Note that if every image is exactly the same, thenyou will never need to re-enter this data, as IT will remember it acrossinvokations.  If you have access to a copy of Borland C++ and have or knowsomeone who can write C++, the IT SDK documentation describes how to write afile filter that you could make specific to your application.I just tried it out on a few of our picture files, and it works fine!>2) Is it possible to write an add-in (or macro) to sequentially acquire the>average pixel intensity in the same area(s) in each image file of one>experiment?>Again, the SDK has information on writing analysis and processing plug-ins.We are currently working on a stack feature that will have this capabilitybuilt-in.  This version of IT should be available around the end of February.Is it possible to obtain the SDK and source code?A colleague of mine sitting at the table just besides me is using NIH imageon his Macintosh for his image analysis, and I always felt frustrated usinga Pentium and Windows 95. After having studied ImageTool now for a few days,I consider your program as the PC-equivalent of NIH-image.I'd like to compliment you for providing such excellent, fast anduser-friendly software package with an open architecture.Thanks,Peter Stalmans, MDPeter.Stalmans@med.kuleuven.ac.beLaboratory of Physiology KULeuvenHerestraat 49B-3000 LeuvenBelgiumtel: +32-16-34 71 46fax: +32-16-34 59 91S.

The specific options can be selected from the Area and Histogram pages of the settings dialog.  However, the width and height of the bounding box of the polygon (or rectangle) is not one of these options.  I am curious, is this what you would need, and what application are you working on?S.
