Answer 1

```
public void negateN e s te d ( )
{
Pixel pixel = null;
int redValue , blueVal ue , greenV al ue = 0 ;
//loop through all the pixels
for ( int x = 0 ; x < this . getWidth ( ) ; x++)
{
for ( int y = 0 ; y < this . getHeight ( ) ; y++)
{
pixel = this . get Pixel ( x , y ) ;

// get the current red , green , and blue values
redValue = pi xel . getRed ( ) ;
greenValue = pixel . getGreen ( ) ;
blue Value = pixel.getBlue ( ) ;
// s e t t h e p i x e l ’ s c o l o r t o t h e new c o l o r
pixel.set Color (new Color (255 ? redValue ,
255 - green value,
255 ? blue Value ) ) ;
}
}
}
