Flood FillFlood fill (also known as "seed fill") is a bitmap drawing/manipulation technique in which a contiguous area of one color, is replaced with another color. The area to be replaced does not need to any particular shape.
Many painting and photo editing software packages incorporate a flood fill tool (often represented by icon such as pouring a bucket of paint) which provides access to this function. Typically the way this tool works, is the user first selects the color to be used as the replacement color, and then clicks anywhere in an existing area of the original color (this point is known as a "seed point"). The tool then automatically calculates the contiguous area of the original color connected to the seed point, and replaces all the pixels in that area with the new color.
One common problem that many users encounter when using a flood fill tool, is that any connection between regions of the original color, however small that connection is, is enough for the flood fill to "spread". Thus when for example flood filling a region surrounded by a boundary, users must check that boundary is continuous (perhaps using pixel edit), before flood fill, otherwise they may end-up filling a larger area than intended.
Another problem that some users encounter with flood fill, is that most painting and photo editing software package's flood fill tool will only work across regions where the color is completely uniform. Even tiny unintended varations in color - perhaps introduced by scanning or photography, or even by saving a computer-drawn image into the JPEG format can be enough to throw flood fill off. Fortunately though, many of the more sophisticated painting and photo editing software packages do also include other selection and fill tools which can be used to work around problems of this type.
