ねえ、これは正しく動作しますが、4 ウェイと比較した後、違いが見つかりません...これを渡すと、8 ウェイフラッド アルゴリズムを実装する正しい方法と見なされますか? はい/いいえの答えで十分ですが、続行する前に専門家に尋ねることにしました
private void flood8(int col, int row, Color startColour) {
if (startColour.equals(getPixel(col, row))) {
setPixel(col, row);
// this bit makes the animation work by
// drawing intermediate results, and slowing the updates down
synchronized (this) {
draw();
}
try {
Thread.sleep(10);
} catch (InterruptedException e) {
}
// now we call the routine recursively for each neighbour
// the "guard" surrounding each call ensures that we do
// not try to keep going past the edge of the raster
if (col + 1 < COLS) {
flood4(col + 1, row, startColour);
System.out.println("Position1 " + col + ", " + row );
}
if (col - 1 >= 0) {
flood4(col - 1, row, startColour);
System.out.println("Position2 " + col + ", " + row );
}
if (row + 1 < ROWS) {
flood4(col, row + 1, startColour);
System.out.println("Position3 " + col + ", " + row );
}
if (row - 1 <= 0) {
flood4(col, row - 1, startColour);
System.out.println("Position4 " + col + ", " + row );
}
if (col + 1 < COLS && row + 1 < ROWS) {
flood4(col + 1, row, startColour);
System.out.println("Position1 " + col + ", " + row );
}
if (col + 1 < COLS && row - 1 >= 0) {
flood4(col - 1, row, startColour);
System.out.println("Position2 " + col + ", " + row );
}
if (row - 1 >= 0 && row + 1 < ROWS) {
flood4(col, row + 1, startColour);
System.out.println("Position3 " + col + ", " + row );
}
if (row - 1 >= 0 && row - 1 >= 0) {
flood4(col, row - 1, startColour);
System.out.println("Position4 " + col + ", " + row );
}
}
