Subject: Detect edges from defined area

My project is:
I have "human cells" image and need to draw the only one cell edge when user click over the cell with mouse
Can I do that with Envision Image Library????
Steps:
1) user load the image (like the attached)
2) user click over a image area
3) the library need to draw in the edge a 1 pixel line and give the area (eg. heigh and width)

The work will be always:
1) Image will be black, white and gray tons
2) the user will click over the center of a cell

I dont want that you tell me step-by-step how to do that, I will work on that my self after study the library, but download the the demo and the Image|Edge detection dont work how I spected there, coz in demo I cant define the area.

Any comments or suggestions is appreciated.
