Fence fill algorithm
WebAlgorithm. Step 1 − Initialize the value of seed point s e e d x, s e e d y, fcolor and dcol. Step 2 − Define the boundary values of the polygon. Step 3 − Check if the current seed point is of default color then repeat the steps 4 and 5 till the boundary pixels reached. If getpixel (x,y) = dcol then repeat step 4 and 5.

WebMar 27, 2024 · In the rail fence cipher, the plain text is written downwards and diagonally on successive “rails” of an imaginary fence, then moving up when we reach the bottom rail. When we reach the top ... Flood fill, also called seed fill, is a flooding algorithm that determines and alters the area connected to a given node in a multi-dimensional array with some matching attribute. It is used in the "bucket" fill tool of paint programs to fill connected, similarly-colored areas with a different color, and in games such as Go and Minesweeper for determining which pieces are cleared. A variant called boundary fill uses the same algorithms but is defined as the area connected to a given node that …
WebAlgorithms that fill interior-defined regions are called flood-fill algorithms; those that fill boundary-defined regions are called boundary-fill algorithms or edge-fill algorithms. Boundary Fill Algorithm : In this method, edges of the polygons are drawn. WebAlgorithm for 4-Connected Pixel Concept Step 1: First initialize the 4 values namely x, y, Fill-color and Default-color.Where x and y are coordinate positions of the initial interior pixels. Fill-color is the color we want to fill and Default- color is the default color of the interior pixel. Step 2: Define the boundary values of the polygon. Step 3: Check if the …
