Hello Ruben,
Here is ome sample code for creating an icon image to be drawn on the
map. A bitmap image might be similar.
Mike
/**
* a base class for all icon-type images
*/
public class IconObject extends GraphicObject
{
// the icon for this object
protected OMScalingIcon omIcon = null;
/**
* create an image icon
*/
protected void init (float lat, float lon, String fileName) throws
GraphicException
{
if (fileName == null)
{
throw new GraphicException ("PointObject: null filename");
}
ImageIcon imageIcon = new ImageIcon(fileName);
if (imageIcon == null)
{
throw new GraphicException ("PointObject: null ImageIcon");
}
omIcon = new OMScalingIcon(lat, lon, imageIcon);
if (omIcon == null)
{
throw new GraphicException ("PointObject: null OMScalingIcon");
}
ConfigApi cfgApi = new ConfigApi(App.getInstance().getConfigData());
omIcon.setMinScale(cfgApi.getIconMinScale()); //icon will
be scaled (smaller) until map scale <= this value
omIcon.setMaxScale(cfgApi.getIconMaxScale()); //icon will
be scaled (larger) until map scale >= value
omIcon.setBaseScale(cfgApi.getIconBaseScale()); //at map
scale of 1:500,000 the icon will appear full size
omIcon.setSelectPaint(Color.red);
}
