The following is a short program that was expected to show a bitmap
image.

o-----------o -o ------ o/
/ \ \

/ /
o -o
The left is what I created using bitmap, but the right is what I actually
get(sort of). Could someone out there please give me some advice as what
my mistake is? Your help will be greatly appreciated.

P.S. simplenet is a file containing an array of bits representing
the image(100x100).
