[OpenLayers-Users] Editing polygon in OL

[Diego Roberto]

I am developing an application and need to draw a polygon by clicking on it and be able to edit the vertices. That is, by vertices of the polygon can not move, diminur increase among others. I found an example in OL but I'm with a doubt. The example is this link:
http://www.openlayers.org/dev/examples/modify-feature.html

From
what I saw in the example, I can edit the position of the polygon, the
size and rotation, more than each vertex independently. I could not find an example that when you click on that corner can make the changes.

Does anyone have any information or link that can help me?

Thank all.
Diego Roberto
