Set pixel color in original image

The code in Listing 5

• creates a new Color object based on values in text fields of Figure 3, and
• changes the color of the corresponding pixel in the original image to the new color.

At this point, the color of the pixel in the original image has been modified.

          Color newColor = new Color(
                                 redInt,greenInt,blueInt);
          pix.getPixel(xIndex,yIndex).setColor(newColor);
