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).
