1: go to http://java.sun.com/products/java-media/jai/current.html
download Java Advanced Imaging 1.1.2
2: put the lib in your jdk
3: following is the sample i convert my tif to bmp file:
import java.io.FileOutputStream;
import java.io.OutputStream;
import javax.media.jai.JAI;
import javax.media.jai.RenderedOp;
import com.sun.media.jai.codec.BMPEncodeParam;
import com.sun.media.jai.codec.ImageCodec;
import com.sun.media.jai.codec.ImageEncoder;

public class Test {
public static void main(String[] args) throws Exception{
String inputFile = "me.tif";
String outputFile = "out.bmp";
RenderedOp src = JAI.create("fileload", inputFile);
OutputStream os = new FileOutputStream(outputFile);
BMPEncodeParam param = new BMPEncodeParam();
ImageEncoder enc = ImageCodec.createImageEncoder("BMP", os,
param);
enc.encode(src);
os.close();
}
}
for more details, you can go & check from :

反过来你就可以把bmp转成tif的了...
只不过用不同的codec..
所以可以在bmp, jpg, png, tif之间相互转换....
