question: public static BufferedImage cropImage ( BufferedImage image , int cropWidth , int cropHeight ) { BufferedImage retImg = null ; int width = 0 ; int height = 0 ; width = image . getWidth ( ) ; height = image . getHeight ( ) ; retImg = new BufferedImage ( cropWidth , cropHeight , BufferedImage . TYPE_INT_RGB ) ; for ( int i = 0 ; i < cropWidth ; i ++ ) { for ( int j = 0 ; j < cropHeight ; j ++ ) { if ( i < width && j < height ) { retImg . setRGB ( i , j , image . getRGB ( i , j ) ) ; } else { retImg . setRGB ( i , j , 0 ) ; } } } return retImg ; }
target:  Method crop an image to the given dimensions. If dimensions are more than the input image size, then the image gets padded with black color
