I have some picture like the one seen below. Now, I'm trying to create some tooltip with some descriptions when moving with the mouse over a body part e.g. "this is the head", "This is the left arm" asf. My first idea how to do this is to create a transparent graphic object overlay it with the specific body part (which maybe is not the easiest way)

But three questions arise:

  1. How to create more complex forms like the shape of the legs,arms in an easy way?

  2. How to align/overlay these forms exactly to the areas (e.g. upper arm, lower arm, legs) shown in this picture? I somehow need to set the beginning and the end of the area I want (e.g. red dots in picture) and then create those complex forms which exactly fit to the body part.

  3. How to assign a tooltip to those overlaid forms?

(For clarity: It's not about the body picture, but more about creating complex forms in an easy way. The picture is only the example which gave rise to the question)

I seem to recall a similar question posted long ago, perhaps answered by Heike. –  Mr.Wizard Jun 6 at 12:01

Vaguely related, but not the one I was thinking of: (2524). I think perhaps I was remembering this, which is probably much more relevant: (9405) –  Mr.Wizard Jun 6 at 12:03

If you already "cut" the body parts with different colors it should make things easier I think. –  Öskå Jun 6 at 12:18
    
Then PixelValuePositions might help. –  Öskå Jun 6 at 12:39
    
Interesting, but broad - could you specify how you want to generate the shapes and add some sample data? –  Yves Klett Jun 23 at 6:21
