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

I changed function that equals by pixels in Groovy, may be helpful:

boolean imagesAreEqual(BufferedImage image1, BufferedImage image2) {
    if (image1.width != image2.width || image1.height != image2.height) {
         return false
    }
    for (int x = 1; x < image2.width; x++) {
        for (int y = 1; y < image2.height; y++) {
             if (image1.getRGB(x, y) != image2.getRGB(x, y)) {
                 return false
             }
        }
    }
    return true
}

Answer 2

I can't think of anything besides a brute force "do loop":

  BufferedImage bi1, bi2, ...
   ...
  Raster r1 = bi1.getData();
  DataBuffer db1 = r1.getDataBuffer();
  if (db1.getSize() != db2.getSize ())
     ...
  for (int i = 0; i < db1.getSize(); i++) {  
    int px = db1.getElem(i);
  }
