Large Scale Behaviour
The primary technique used to control a flood fill will either be data-centric or process-centric. A data-centric approach can use either a stack or a queue to keep track of seed pixels that need to be checked. A process-centric algorithm must necessarily use a stack.
A 4-way floodfill algorithm that uses the adjacency technique and a queue as its seed pixel store yields an expanding lozenge-shaped fill.
Efficiency: 4 pixels checked for each pixel filled (8 for an 8-way fill).
A 4-way floodfill algorithm that use the adjacency technique and a stack as its seed pixel store yields a linear fill with "gaps filled later" behaviour. This approach can be particularly seen in older 8-bit computer games, such as those created with Graphic Adventure Creator.
Efficiency: 4 pixels checked for each pixel filled (8 for an 8-way fill).

Famous quotes containing the words large, scale and/or behaviour:
“Nature has ordained that the man who is pleading his own cause before a large audience, will be more readily listened to than he who has no object in view other than the public benefit.”
—Titus Livius (Livy)
“‘Tis very certain that each man carries in his eye the exact indication of his rank in the immense scale of men, and we are always learning to read it. A complete man should need no auxiliaries to his personal presence.”
—Ralph Waldo Emerson (1803–1882)
“When we read of human beings behaving in certain ways, with the approval of the author, who gives his benediction to this behaviour by his attitude towards the result of the behaviour arranged by himself, we can be influenced towards behaving in the same way.”
—T.S. (Thomas Stearns)
