Query and zoom mode

Sorry for my late answer.
Your proposal solves the problem only partially. When I substitute the
"shape" value with the mapextent, I get the whole map as resulting image,
but the selected features are not only these selected by my rectangle
shape. Instead, all features of the current mapextent are selected.

Philip
