I'm about to embark on writing a little program that puts up an image, alows the user to outline a section of it, and do some calculations for the pixels in the selected section (e.g. calculate what fraction of the pixels are greater than some threshold) This is obviously a program that someone like David (Fanning) could write in his sleep but I've been away from widgetizing for a few months (how soon they forget !). It probably wouldn't be the worst thing for me to have to do this from scratch but since I'm in a bit of a hurry I thought I'd ask if anybody knows of any programs in any of the available libraries that sound like they do something like this and that I could modify. (David, I checked your web site and nothing seemed all that close to what I need) Thanks for any tips, advice,... -- KY ------------------------------------------------------------ ------- Karl Young Phone: (415) 750-2158 lab UCSF (415) 750-9463 home VA Medical Center, MRS Unit (114M) FAX: (415) 668-2864 4150 Clement Street Email:kyoung@itsa.ucsf.edu San Francisco, CA 94121 ------------------------------------------------------------ -------

You are not the only one who has accused me of writing programs in my sleep, believe me! :-) In fact some of the nonsense I have had on my web page lately would have been greatly improved if I HAD written it in my sleep. But that's another story... I will tell you that if *I* needed a neat ROI-like tool for medical images I would hot-foot it over to Phil Williams site and have a look at his XDISPLAY program. I think Phil is is the process of updating it from handles to pointers, but it is a very nice tool. I think it will probably do all you need and much more.
