Processing: Flip a PImage horizontally

I needed a mirror image of a PImage in my Processing project, so I came up with this little snippet:

public PImage getReversePImage( PImage image ) {
 PImage reverse = new PImage( image.width, image.height );
 for( int i=0; i < image.width; i++ ){
  for(int j=0; j < image.height; j++){
   reverse.set( image.width - 1 - i, j, image.get(i, j) );
  }
 }
 return reverse;
}
