Hi all,

 

I'm trying to write a script which asks the user upload an image,

 

then let him draw a rectangle around an object in the image (like 'tagging' in facebook),

 

and then sends the rectangler image to a java services, which process the image and outputs a string.

 

I have no clue about how to let the user to draw a rectangle.

 

I used this site http://tech.hawkfield.be/archives/000009.html to load an image and display it,

 

now what?

 

Good day  :D
