Re: [OpenLayers-Dev] Draw boxes on the image pressing shift key
I see now what you're saying. I clicked on the checkbox and now the boxes are inline of horizontal line. But is there a way to modify the box drawn?/ Thanks.

It seems like it will be helpful for resizing the square box, but how to move this square and the square box seems to be in 45 degree angle to the horizontal line. I need square to be drawn inline with horizontal line. It should be resizable by dragging it edges like we see in the Jquery plugin I mentioned. http://odyniec.net/projects/imgareaselect Thanks again for your help. I really appreciate it.

Re: [OpenLayers-Dev] Draw boxes on the image pressing shift key
Hi, you could use OpenLayers.Control.TransformFeature for moving/reshaping your boxes. See http://openlayers.org/dev/examples/transform-feature.html for an example. Regards, Andreas.
