import java.io.IOException;
import javax.swing.ImageIcon;

public class ImageResize
int setWidth;
int setHeight;
com.jiva.application.auth.AppSession appSession;
public void setWidth(int width)
public void setHeight(int height)

public String imageProps(String path) throws FileNotFoundException, IOException
File source=new File(path);
Image inImage = new ImageIcon(source.getAbsolutePath()).getImage();
int imageWidth=inImage.getWidth(null);
int imageHeight=inImage.getHeight(null);
int returnImageWidth=setWidth;
int returnImageHeight=setHeight;
double ReturnImageRatio = (double)returnImageWidth/ (double)returnImageHeight;
double ImageRatio = (double)imageWidth / (double)imageHeight;
if (ReturnImageRatio < ImageRatio))
returnImageHeight = (int)((double)returnImageWidth / ImageRatio);
returnImageWidth = (int)((double)returnImageHeight * ImageRatio);
String x=Integer.toString(returnImageWidth)+"."+Integer.toString(returnImageHeight);

return x;
