Can someone please tell me or point me to some literature that explains the
logic behind the below piece of code (Taken from calculateBounds method of
Map class)?
var size = this.getSize();<Returns view port size>
var w_deg = size.w * resolution;
var h_deg = size.h * resolution;
extent = new OpenLayers.Bounds(center.lon - w_deg / 2,
center.lat - h_deg / 2,
center.lon + w_deg / 2,
center.lat + h_deg / 2);

Cheers,
Abhi
