color:#1F497D'>Note the “buffer” parameter. If this is set to
true then a textbox will be visible beside the button., if false, then the
textbox will be hidden. The textbox id is called “featureBuffer”
so you can use javascript to set it if it is hidden. This textbox is the
buffer amount you wish to use in your feature ROI selection. It is is the
same units as your mapfile. I.e. if your map is in metres then entering
5000 in this textbox would set a feature buffer size of 5000 metres.<o:p></o:p></span></p>

queried in order to create a feature ROI with the supplied buffer. The active
layer is usually set through the LegendTemplate widget. Checkout the
Chameleon samples to see how this is implemented.<o:p></o:p></span></p>

widget. It allows you to create an ROI (region of interest) by selecting
a feature on the map and applying a buffer to it. Take a look at the
ROIManager/ROIRenderer.php code and how it implements the buffering using
PHPMapscript. You will need a later version of PHPMapscript compiled with
GEOS for this to work.</span><o:p></o:p></p>
