[Geomoose-users] debugging the identify function

[Brent Fraser]

Dan,

   I ended up adding the following to ServiceManager.js (around line 160) in my 
version of GM 1.6.1:

} else if(inputType.match(/imgpoint/)) {
	var delim = inputs[i].getAttribute('delim');
	if(!delim) { delim = ' '; }
	var pImg = ServiceMap.groundUnitsToPixels(p[0]);
	var pValue = pImg.toString(delim);
	newInput.setAttribute('type','hidden');
	newInput.setAttribute('value', pValue);		


with the following in the XML (note the type="imgpoint"):

<service title="Identify" default="true" cursor="url(cursors/identify2.cur), auto"
      icon="shared/images/toolbar/identify.jpg"
      highlight="shared/images/toolbar/identify_selected.jpg"
      locked="true" shape="point">
	<url>/cgi-bin/mapserv.exe</url>
	<input type="file" name="map" value="./identify.map"/>
<!--
	<input type="point" name="mapxy" delim=" "/>
-->			
	<input type="imgpoint"      name="imgxy"   delim=" "/>

	<input type="extent"        name="imgext"  delim=" "/>
	<input type="visiblelayers" name="layers"  delim=" "/>
	<input type="imagesize"     name="imgsize" delim=" "/>
	<input type="hidden"        name="mode"    value="nquery"/>
</service>

With those changes, the Identify service now will work with points.

One problem I noticed is that because the hot-spot for the Identify cursor is 
not at the center of the cross (it is at the upper left limit of the cursor 
image), I need to set my TOLERANCE value to 20 pixels so mapserver will find a 
feature at the cross center point.

Is there some way to set the cursor hot-spot location?

Thanks!
Brent Fraser
