Question

I have a custom class vtools.Image that extends BufferedImage.

Then I am reading a picture from a url using ImageIO.read and sacing this as BufferedImage.

BufferedImage bfImg = ImageIO.read(imageUrl);

but then I would need to convert this bfImg into vtools.Image but when I try to cast it I am getting a ClassCastException error. What is the other way of converting these two?

Answer 1

EDIT: At first I thought, that you could simply write a special constructor, that takes a BufferedImage. But that is not that easy. So I would recommend to write a wrapper class like this:

package vtools;

import java.awt.image.BufferedImage;

public class Image {

    BufferedImage image;

    public Image(BufferedImage image) {
        this.image = image;
    }

    // Add your methods, that modify the image or return the result.
}
