Is there a simple way to compare BufferedImage instances?

Question

I am working on part of a Java application that takes an image as a byte array, reads it into a java.awt.image.BufferedImage instance and passes it to a third-p

Answer 1

You could write your own routine for comparison!

int width;
int height;
boolean imagesEqual = true;

if( image1.getWidth()  == ( width  = image2.getWidth() ) && 
    image1.getHeight() == ( height = image2.getHeight() ) ){

    for(int x = 0;imagesEqual == true && x < width; x++){
        for(int y = 0;imagesEqual == true && y < height; y++){
            if( image1.getRGB(x, y) != image2.getRGB(x, y) ){
                imagesEqual = false;
            }
        }
    }
}else{
    imagesEqual = false;
}

This would be one way!!!
