Flood Fill Algorithms In C# And Gdi+

FLOOD FILL ALGORITHMS IN C# AND GDI+

Introduction/Overview

GDI+ does not have built-in flood fill capabilities. This example shows you how to create three different flood-fill algorithms for GDI+. It expands on the typical flood fill implementation by allowing adjustable color tolerance, and optional 8-way (diagonal) branching.

The flood fill algorithms will not be as fast as they would be if they were written in assembler, but you most likely won’t notice this in ordinary use, because they are still quite fast.

Background

There are two main types of flood fills. The most common is 4-direction flood fill. This type of flood fill starts from a single point and branches up, down, and to the right and left. The 8-direction flood fill is similar to the 4-direction, except that it also branches diagonally.
