flood-fill

问题 i just try to use FloodFill class and i found strange problem with coloring. Lets start with code: public class FloodFill { public void floodFill(Bitmap image, Point node, int targetColor, int replacementColor) { int width = image.getWidth(); int height = image.getHeight(); int target = targetColor; int replacement = replacementColor; if (target != replacement) { Queue<Point> queue = new LinkedList<Point>(); do { int x = node.x; int y = node.y; while (x > 0 && image.getPixel(x - 1, y) ==

问题 I am creating a drawing app. I have succeeded to do everything. When I paint the image with a dark color, some white pixels appear at the edges. I tried to change the value of r + g + b and also alpha but no use. Can any one help me out? You can check the live site from here. Anyone who will help me, I shall grant 50 bounty to him/her. Thanks. This is my code. <script type="text/javascript"> var initial = screen.width - 50; if (initial < 1000) { initial = 1000; } var firsttime = null; var

问题 I got a grid with two points. I want to calculate the amount squares each point can reach before the other. Currently I implement a FloodFill-Algoritm, which can calculate the amount of squares one point can reach. How can I change that algorithm to do the "flooding" for both points simaltaneuosly or at least one after another? 回答1: What do you mean by "each point can reach before the other"? It looks to me like you need a BF search. Use a FIFO queue like so: Let p1 and p2 be the positions of

问题 I'm working on a small drawing application in Java. I'm trying to create a 'bucket-fill' tool by implementing the Flood Fill algorithm. I tried using a recursion implementation, but it was problematic. Anyway, I searched around the web and it seems that for this purpose, a non-recursive implementation of this algorithm is recommended. So I ask you: Could you describe a non-recursive implementation of the Flood Fill algorithm ? An actual code example, some pseudo-code, or even a general

问题 I am trying to find a solution of the puzzle game 'Flood It'. The main idea is to turn a whole N*M game board of k different colors into a single color. I have to start from the top left corner of the board and turn the same colored block into one of the colors of neighboring nodes and thus moving ahead and flooding the whole board into a single color at last. For example: Initial Board: 1 1 1 2 2 3 1 1 2 3 4 5 1 1 1 1 3 4 1 4 3 2 1 5 2 3 4 5 1 2 Final Board: 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1

问题 I'm trying to make a Minesweeper-like game in Java and I've got most of it to work. Something I need help with is FloodFill - http://en.wikipedia.org/wiki/Flood_fill. Can someone explain how it works? I've looked online but I don't really understand the explanation so I thought it would be easier to ask here. In my Minesweeper I have: JButton[] btn = new JButton[100]//buttons being clicked and displaying the values/bombs int[] mines = new int[100];//int array holding the values for each

问题 im working in a simple graphical library in C with turbo C++ because im developing a very primitive version of a paint style program, everyting works well but i can´t get the flood fill algorithm to work. Im using the 4 way flood fill algorithm, first i tried with the recursive version but it only work with small areas, filling large areas make it crash; reading i found that implement an explicit stack version of it solve the problem but i don´t really see it. I have developed a stack like

问题 I want to use bitmapData.floodfill() method to fill the image by using "onclick" event (like paint bucket does). But the problem is that this method doesn't work as i excepted when i use transparent images(png, gif). It will only fill using white color(or alpha=0 as i think) when i use something different (like blue, red, etc). This is how it looks when i fill Jerry mouse with red color clip2net.com/s/2nW65 and here is the example i used with Embed image: var container:MovieClip = new

问题 I am new in Flutter. I want to select a zone from the below images. How can I achieve the flood or bucket fill in Flutter? Can someone help me out with your Knowledge in Flutter Dart..?? 回答1: You can do this by using shapes wrapped in an InkWell : import 'package:flutter/material.dart'; void main() => runApp(MyApp()); class MyApp extends StatefulWidget { MyApp({Key key,}) : super(key: key); @override _MyAppState createState() => _MyAppState(); } class _MyAppState extends State<MyApp>{
