Use ValueMapLabelRenderer object in ArcIMS Java Viewer

Summary

Instructions provided describe how to use ValueMapLabelRenderer in the ArcIMS Java Viewer object model.

Procedure

Code:

function setValueLabelRenderer(){

var mapApplet=parent.mapFrame.document.IMSMap;
var layer=mapApplet.getSelectedLayer()

if (layer==null) {
	alert('No Layer is active!')
	return
}

//create a valuemap label renderer and set the value field
var labelRenderer=mapApplet.createRenderer('VALUE_LABEL_RENDERER')
labelRenderer.setField(layer,'STATE_NAME');

//call setFields method to specify the collection of label fields
var col = mapApplet.createCollection();
col.addStringElement('STATE_NAME');
labelRenderer.setSeparator(':');
labelRenderer.setFields(layer,col);

// create a label symbol object 
var labelSymbol = mapApplet.createSymbol('TEXT_SYMBOL');

// set the label symbol object’s display properties 
var newColor1 = mapApplet.createColor(255,0,0);
labelSymbol.setFont("Arial",10);
labelSymbol.setAntialiasing("true")
labelSymbol.setFontColor(newColor1);
labelSymbol.setTransparency(1.0);

//create a defaultsymbol for non-matching values
var defaultLabelSymbol=mapApplet.createSymbol('TEXT_SYMBOL')
defaultLabelSymbol.setTransparency(0.0);

//assign renderer to unique values
labelRenderer.setSymbolForUniqueValue(labelSymbol,layer,'STATE_NAME','California');
labelRenderer.setSymbolForUniqueValue(labelSymbol,layer,'STATE_NAME','Oregon');
labelRenderer.setSymbolForUniqueValue(labelSymbol,layer,'STATE_NAME','Nevada');

//assign the default symbol 
labelRenderer.setDefaultSymbol(defaultLabelSymbol);

//set ValueMapLabelRenderer to the layer 
mapApplet.setLayerLabelRenderer(layer, labelRenderer);

//redraw the map to apply the renderer changes

mapApplet.redraw();

}
