I think I figured out the code that focuses on the top right corner but I'm having trouble with the color requirements. Any help would be greatly appreciated. Thanks.

Write a Picture method that examines every pixel in the top right quarter of the picture (see diagram below). When it finds a pixel whose green component is less than the blue component, it changes the value of the pixel to a shade of gray equal to the value of the red component. Because this method only examines pixels in the top quarter of the picture, the rest of the picture should remain unchanged.

Describe at least one parameter you would add to make this method more general. The description should include both a name for the parameter and a one-sentence summary of what that parameter would do. You do not need to write/modify any code for this question.
