View Full Version : Image Annotation

14 Mar 2011, 7:26 AM
Hello all.

I just wanted to pick the collective brains of the community.

I'm investigating building a form with all the usual trimmings, but more importantly I want to allow the user to click on a point on an image and mark it (with a X for example) and then potentially annotate the image to elaborate on why they marked it at that point.

I've thought about a few approaches. Using an image map and collecting the co-ordinates of a click that way. I'm currently looking into using a drawing library to re-mark the co-ordinates when the form re-loads. Something like http://raphaeljs.com/ would do the trick I think.

Does anyone already have a solution for this, or some ideas on how to achieve this functionality?

Any thoughts would be much appreciated.

Have a peek at Saki's example pages (http://examples.extjs.eu/).
Under Panel/Window->Handling Item Clicks you maybe find what you need.
