Hi everybody! Is there any way (method, utility class) to draw an animated
curve on a JMapPane component.
In fact what I want to do is this:
I have a list of coordinates that represents succesives registred position of
an object that I want to track. On my map I want to add a facility to show just
like a progressive line the movement of that object by ploting every coordinate
in the list on the map. But I want this process to be continuous (like if the
line was drawing itself) from time t0 to time t1 where t1 - t0 != 0.
If anyone have done this before, some tips or guidance will be very helpfull.
And then I have another problem, I can't display label on my map even though I
use a TextSymbolizer.
I tried this but it didn't work:
if(layerName.equals(ConstantValues.AGENT_LAYER_NAME) && SABC_RED == null){
Mark textMark = sb.createMark(sb.attributeExpression("Nom"),
sb.createFill(Color.RED, 0.5), null);
Graphic graph = sb.createGraphic(null, new Mark[] {
textMark }, null,
1, 5, 0);
newStyle.addFeatureTypeStyle(sb.createFeatureTypeStyle("AgentPoint",
new Symbolizer[] { pointSymbolizer,
sb.createPointSymbolizer(graph) }));
SABC_RED = newStyle;
}else{
newStyle.addFeatureTypeStyle(sb.createFeatureTypeStyle(pointSymbolizer));
}
}
MapLayer maplayer = new DefaultMapLayer(sourceM, newStyle);
For another situation I tried this also but the result wasen't better:
PolygonSymbolizer ps = sb.createPolygonSymbolizer(color1,
color2, 2);
FilterFactory ff = FilterFactoryFinder.createFilterFactory();
Font font = FontImpl.createDefault(ff);
TextSymbolizer ts = sb.createTextSymbolizer(Color.BLACK, font,
"quartier");
newStyle.addFeatureTypeStyle(sb.createFeatureTypeStyle(ps));
MapLayer maplayer = new DefaultMapLayer(sourceM, newStyle);
If there is something I'm doing wrong please just tell me. I need to have this
project very soon but still stuck on 'basic' issues.
P.S: I'm using geotools-2.5.6 and Netbeans 6.7.1
Thanks in advance for reading and possible help!
