Which is an example of a flood fill algorithm?

Which is an example of a flood fill algorithm?

Flood Fill Algorithm Flood fill (also known as seed fill) is an algorithm that determines the area connected to a given node in a multi-dimensional array.

What does flood fill with 4 directions mean?

Recursive flood fill with 4 directions Flood fill, also called seed fill, is an algorithm that determines and alters the area connected to a given node in a multi-dimensional array with some matching attribute.

How does flood fill work in Microsoft Paint?

Fortunately, today I finally got around to it, so here is flood fill. Flood fill is a method used in programs such as Microsoft Paint or Photoshop to fill a selected area with one color. It scans an area for similar colors and fills those areas with a replacement color.

Is the flood fill rule good for drawing polygons?

Note that flood filling is not suitable for drawing filled polygons, as it will miss some pixels in more acute corners. Instead, see Even-odd rule and Nonzero-rule .

Flood fill algorithm helps in visiting each and every point in a given area. It determines the area connected to a given cell in a multi-dimensional array. Following are some famous implementations of flood fill algorithm: Bucket Fill in Paint: Clicking in an area with this tool selected fills that area with the selected color.

How does flood fill prevent stack overflow?

Moving the recursion into a data structure (either a stack or a queue) prevents a stack overflow. It is similar to the simple recursive solution, except that instead of making recursive calls, it pushes the nodes onto a stack or queue for consumption, with the choice of data structure affecting the proliferation pattern:

Which is the recursive way to do flood fill?

The earliest-known, implicitly stack-based, recursive, four-way flood-fill implementation goes as follows: Flood-fill (node): 1. If node is not Inside return. 2. Set the node 3. Perform Flood-fill one step to the south of node . 4. Perform Flood-fill one step to the north of node 5. Perform Flood-fill one step to the west of node 6.
