question: public boolean imageUpdate ( Image img , int infoflags , int x , int y , int width , int height ) { if ( ( infoflags & ImageObserver . ALLBITS ) != 0 ) { if ( colorModel == COLORMODEL_IMAGEICON ) { setImage ( img ) ; } } if ( ( infoflags & ImageObserver . WIDTH ) != 0 ) { this . width = width ; } if ( ( infoflags & ImageObserver . HEIGHT ) != 0 ) { this . height = height ; } return ! ( this . bitmap != null && this . width > 0 && this . height > 0 ) ; }
target:  From the Image Observer Interface. Called when the image bits have arrived, and therefore calls setImage() to reset all the OMRasterObject parameters. <br> Don't call this method!
