I've implemented something similar in this way
Let url be the URL of the selected file.
I've the easy class ImmaginePlugIn, that simply puts the image in the
upper left corner, obviously you have to add it to a layer
Tell me if you want something different....
package com.bbn.openmap.plugin;
import java.awt.*;
import java.net.*;
import javax.swing.*;
import com.bbn.openmap.omGraphics.*;
import com.bbn.openmap.proj.*;
/**
* _at_author Luigi Trevisant
* _at_version 1.0
*/
public class ImmaginePlugIn extends AbstractPlugIn{
ImageIcon ii;
URL url;
OMRaster omr;
public ImmaginePlugIn(URL url) {
this.url = url;
ii = new ImageIcon(url);
/*
This plugin doesn't extend the image to fit the map area.
It simply puts the image in the upper left corner
*/
if(ii != null)
omr = new OMRaster(1,1,ii);
}
public OMGraphicList getRectangle(Projection p) {
OMGraphicList list = new OMGraphicList();
if(omr != null){
list.add(omr);
list.generate(p);
}
return list;
}
}
