Write a program employing the iac++ library to carry out the region filling algorithm as described on pg. 532 of Gonzalez and Woods.
An example image contains an object's
boundary. It is suitable for reading as an image of type
IA_Image<IA_Point<int>,IA_Bit>.
Your program should take such a boundary image from the file named "in.pbm" and read (from cin) the integer x and y coordinates of the seed point for the region filling algorithm.
It should write to standard output, the
IA_Image<IA_Point<int>, IA_Bit> image that is
the result of carrying out the region filling algorithm upon the image
and the point.
