WebA variant called boundary fill uses the same algorithms but is defined as the area connected to a given node that does not have a particular attribute. [1] Note that flood filling is not suitable for drawing filled polygons, as it will miss some pixels in more acute corners. [2] Instead, see Even-odd rule and Nonzero-rule . WebThe boundary of a given pattern P, is the set of border pixels of P . Since we are using a square tessellation, there are 2 kinds of boundary (or border) pixels: 4-border pixels and 8-border pixels. A black pixel is considered a 4-border pixel if it shares an edge with at least one white pixel.
