Hi,
If you mean just with java (not geotools as mentioned previously) you
could do something like this...
import com.vividsolutions.jts.geom.Geometry;
import java.awt.Color;
import java.awt.Graphics2D;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
// in your drawing method...
int imgWidth = ...;
int imgHeight = ...;
BufferedImage buffImg = new BufferedImage(imgWidth, imgHeight,
BufferedImage.TYPE_INT_ARGB);
Graphics2D g2 = buffImg.createGraphics();
g2.setBackground(Color.WHITE);
g2.setColor(Color.BLUE);
// draw each Geometry e.g by getting Coordinates and using g2.drawLine
//
http://tsusiatsoftware.net/jts/javadoc/com/vividsolutions/jts/geom/Geometry.html#getCoordinates()
// finished drawing: save to file
try {
ImageIO.write(buffImg, "PNG", new
File("c:\\my\\dir\\myfile.png"));
} catch (IOException ex) {
// bummer...
}
