Brent Dove" To: IT Announce ,Subject: NEW ImageTool Version 1.25Message-ID: <01I8Q15WSQL200AG4J@uthscsa.edu>Hello ImageTool Users,ImageTool is one year old today. And it has been an exciting first year. Since August 24, 1995 over 7,000 copies of ImageTool have been downloaded world wide. People are using ImageTool for everything from microscopy, astronomy, material science, satellite imagery, radiology and medicine to the analysis of ant movement patterns. ImageTool is currently being used at virtually every major university in the United States, Europe, Japan and just about every other place you can think of. Major corporations such as Ford, Lockheed, Microsoft, Matshushita, and Sony to name just a few have downloaded UTHSCSA ImageTool.We here at the University of Texas Health Science Center at San Antonio development team would like to thank every user of ImageTool. This has been one of the most rewarding accomplishments of our careers. In just twelve months we have delivered six versions of ImageTool. We have tried to respond to new ideas and fix software bugs as fast as it was possible. With the release of version 1.25 we hope that we have met your expectations. It is our continuing goal to provide the best image processing and analysis software we have the resources to provide.Here are some of the new features in version 1.25. 1) A new installation program, that installs all components necessary to get you up and running. 2) Distribution of three zip files which can easily be distributed on floppy diskettes.3) A Windows 95 Help system interface. 4) Complete support for Data Translation DT3152 & DT3155 running under both Windows 95 and Windows NT. 5) Support for Play Technologies Snappy Video Snapshot parallel port image acquisition device. 6)Improved support for flatbed scanners, such as Microtek, UMAX, Epson and handscanners from Genius. 7) Variable width line profiles for electrophoresis gel analysis. 8) New Software Development Kit (SDK) using Borland's new 5.0 C++ compiler. 9) Easier Plug-in development. 10) Numerous bug fixes and improved algorithms. So where to we go from here? Well we are already busy working on version 2.0. The next version should provide for annotations and painting, a more complete gel electrophoresis plug-in and most importantly a complete scripting language. The scripting language will allow the user to create complex scripts to extend the capabilities of ImageTool without any additional programming language. This is comparable to the macro language used in NIH Image. We hope that these new features will allow more of you to do your job better and easier. We are also improving our developer support to make it easier for developers to write ImageTool plug-ins using conventional computer languages.Thanks again to all the scientists and researchers who have made UTHSCSA ImageTool such a success. So what are you waiting for go ahead and download the new ImageTool. Try the maxrad6.uthscsa.edu ftp site because I don't know when the mirror sites will be updated.  With this new version three zip files must be downloaded unzipped into a temp directory and the setup.exe run.  Good luck and we hope you enjoy.Oh, by the way it won't hurt if you sent some email to the President (howe@uthscsa.edu) or the Dean (kalkwarf@uthscsa.edu) of our university, letting them know how UTHSCSA ImageTool has helped you in your research efforts. So long for now.S.

Brent Dove" To: IT List Subject: Re: Documents Info?Message-ID: <01I8RJNM0VW400AYYP@uthscsa.edu>Recently on ITList,>Is there a site which has an introduction of how to>write and integrate additional plug-ins and/or capabilities>to the basic ImageTools?It is recommended that you use Borland 5.0 C++ for development.  This is not required, in principle you should be able to use any language that is capable to generating a funtional Dynamic Link Library.The best way to get started in writing a plug-in for ImageTool is to first dowload the new Software Development Kit SDK from our ftp site.  This SDK has an installation program that will completely setup a development environment for Borland 5.0 C++.  The SDK contains sample code for every plug-in that ships with UTHSCSA ImageTool.  This includes acquisition, analysis and processing plug-ins.  By looking at the sample plug-in code you should be able to see how it is done.  The SDK also include and extensive help file which is completely cross referenced.  This uses the normal Windows help system.  All functions and calls are explained. We have just added a section in the SDK help which addresses the use of Microsofts Visual C++ development environment in conjunction with Borlands Code.  If you use MVC++ please read this section.If you wish to develop for ImageTool please send and email message directly to me and I will add you to a list of developers.  We hope to start another listserver primarily for developers.  Good luck/S.

Any one of four morphologicaloperations results in reverse of black pixels around the binary imageboundaries. No any effect to the objects in the image. BTW, the polygonfor AOI in this operation is in white color which is not obvious in abinary image.Thanks,Bin------------------------------Date: Tue, 27 Aug 1996 10:38:25 +0000From: hubert@bert.van.forintek.caTo: it-list@sparky.uthscsa.eduSubject: Problem in the centroid calculationMessage-ID: <9608271737.AA26046@sparky.uthscsa.edu>I think there is asmall  bug in the centroid calculation routine.
