1. ) Write a program to create a pgm le with 8x8 checkerboard pattern. Image dimensions will be 800x800 pixels and each black and white cell will be 100x100 pixels. Consider the following gure for details. In the gure B denotes black cells and W denotes white cells.
800
100 100 100
100 B W W

Figure 1: Checkerboard
PGM le format is as follows
P2
Width Height
MaxGray
Data
Width and height are width and height of the image. MaxGray is the maximum gray value. This will be 255 in our case. Data is grayscale pixel values (0 for black, 255 for white) separated by space. When your program produces the pgm les, you can use gpicview or gimp to open pgm les on machines running Linux. Use pgm extension for your les.
Sample pgm le is given below
P2
