Using the Picture class from Worked Example 6.2, apply a sunset effect to a picture, increasing the red value of each pixel by 30 percent (up to a maximum of 255).

Data from worked example 6.2.

WORKED EXAMPLE 6.2 Manipulating the Pixels in an Image A digital image is made up of pixels. Each pixel is a tiny square of a given color. In this Worked Example, we will use a class Picture that has meth- ods for loading an image and accessing its pixels. Problem Statement Your task is to convert an image into its negative: turning white to black, cyan to red, and so on. The result is a negative image of the kind that old-fashioned film cameras used to produce. Cay Horstmann.
