CS 2510 Assignment 2 Dr. Woelfl

The purpose of assignment two is to gain practice with constructing tests for if statements and to take the

time thinking about code before typing rather than using “trial and error” to produce code.

Download the listing for the code given in class and revise it to produce the following bitmap image:

Write your code so that each object has just one test to determine if a pixel is within that particular object.

Descriptions of the objects from front to back are:

• Yellow triangle has height of one-half the image height, forty-five degree sides, and centered with respect the width.
• Blue circle has radius of one-fourth the image height with the center at the center of the image; the color varies with radial distance, from white at the center to blue at the edge. Avoid using the square root function; stay with integer math!
• Red circle has a radius of one-half the width with the center at two-thirds the height from the top edge and at the right edge; the color varies uniformly with the vertical distance, from red at the center to white at the top and bottom.
• Green circle has radius of two-thirds the image height with the center at the upper left corner of the image.
• Background is white.

Do several runs using different values for width and height. Hand in a copy of your code for the tests along with B&W copies of three runs using different heights and widths; the assignment is due at the beginning of class on Thursday of week four.
