Consider the following statement:
The boundary is specified in a single color, and the algorithm proceeds pixel by pixel until the boundary color is encountered.
The above statement defines which of the following algorithms?
Scan-line fill algorithm
Boundary-fill algorithm
Entire fill algorithm
Slide curve algorithm
Correct Answer :
B. Boundary-fill algorithm
Mainly, this algorithm proceeds outward pixel by pixel until the boundary color is encountered. Hence, the given statement definition correctly defines the Boundary fill algorithm.
