I was running IT unders Windows 95, which I installed by upgrading from wfw3.11. I recently upgraded to a new disk, installed Windows95 from scratch, and now IT works fine (so far, at least).

Then I found there is a .hlp file in the rootdirectory of the source code, it is different from the Image Toolsapplication .hlp file.  To access it in Win 95 just click on it.  It isnothuge but it is helpful.  I case you missed it like I did.  I looked for .txt etc. when Iwas really looking for .hlp.  :-)ike.------------------------------Date:          Wed, 10 Jul 1996 08:51:09 EST5EDTFrom: "Heberto Ghezzo" To: it-list@sparky.uthscsa.eduSubject: Re: ImageTool DevelopersMessage-ID: <199607101256.IAA19115@sirocco.CC.McGill.CA>Answering to Bob A. Smith.If I assume that the color space is 3D, ie a cube with [0,0,0] being black and [255.255.255] being pure white, then any 'color' { I do not know the proper name, it is tint, hue...} is represented by a ray from [0,0,0] to a boundary point where one of the coordinates is 255. Along that line we go from 0% intensity [black] to 100% at the boundary. A 'distance' between 2 colors can then be defined as the angle between the 2 vectors. A region of similarity to a given point [r,g,b] can be an ellipse centered at [r,g,b] with major axis on the ray through [r.g.b]. I am definitely not an expert in colors, only a poor bio-statistician, so I was thinking on the lines of defining distance with an ellipse, ie a quadratic in [r,g,b].You said it has already being proven that it does not work?Consider on the other hand, that I do not want to measure color as an artist would define it, but I want to measure 'colorimetrically' the concentration of a given dye, my immuno stain. The color of the dye is modified by interfering tissue and other components of the slide and the intensity of the color is proportional to concentration. For this application I am not concerned with concentration, just presence, correcting from blurring by the extra stuff.Thanks for your comments, and if anybody else wants to comment please feel free....R.

Some==20simple plugins have been developed in our laboratory by me and my students==20to verify the possibility to exploit IT as a base for our new applications.==20My goal is to develop some DLLs improving the capabilities of IT from the==20point of view of image segmentation, edge detection and the gel analysis.==20We plan to acquire images by frame grabbers using MCI protocol. I would lik=e=20to try some non-traditional techniques (pyramidal representation).I have already developed DLL for gel fractions analysis (plug-in of some=20other program) and I am trying to modify my DLL to be acceptable by ImageTo=ol.=20Although we have some experiences with Borland C++ 4.52 and OWL,=20our self-confidence decreases reading your source. Therefore I would very==20appreciate your help and coordination in the future.=20At this moment I have the following problem:- input of my DLL is the rectangular AOI (area of interest) of the analyzed==20  image. How can I get the DIB representing bitmap of selected area=20  (similarly as in your function =84SaveSelectionAs" but not writing DIB to==20  the file). Or how can I use your functions to select AOI inside my DLL.==20- I expect that you fill ImageClientBase and on some message is called=20  ImageClientBase::CmFileSaveSelectionAs. Where and when is called Construc=tor?- Exists there some other simple solution of this problem? (can I find AOI==20  coordinates after the selection written somewhere?)Thank you for great program ImageToolZoltanAddress:  Dr. Zoltan Tomori, PhD,  Institute of Experimental Physics,  Slovak Academy of Sciences  Watsonova 47,  04353 Kosice,  Slovak Republic  E-mail:  Phone: (4295)762240  Fax:   (4295)763754------------------------------Date: Wed, 10 Jul 1996 09:05:25 -0700From: Don Wilcox To: "'ImageTool List Server'" Subject: RE: Pencil and eraser functionsMessage-ID: <>----------From:  Regis the Watcher[SMTP:MTA108@PSUVM.PSU.EDU]Sent:  Monday, July 08, 1996 9:01 PMTo:  wilcox@xroads.comSubject:  Pencil and eraser functionsAm I overlooking something obvious, or does Image Tool not have the =capabilityto perform general drawing functions like draw and erase?You are not missing anything.
