Bearophile,I have written the floodfill in python with stack. But i think I am making something wrong I dont get what i need.Need your opinion.the code follows
def connected(m, foreground=1, background=0): def floodFill4(m, r,c, newCol, oldCol): if newCol == oldCol: print "empty stack" return -1 while(m[r].pop(c)): m[r][c] = newCol if r+1 < maxr and m[r+1][c]==oldCol: if m[r+1][c] == 0:return if r-1 >= 0 and m[r-1][c]==oldCol: if m[r-1][c] == 0:return if c+1 < maxc and m[r][c+1]==oldCol: if m[r][c+1] == 0:return if c-1 >= 0 and m[r][c-1]==oldCol: if m[r][c-1] == 0:return maxr = len(m) maxc = len(m[0]) newCol = 2 oldCol = foreground for r in xrange(maxr): for c in xrange(maxc): if m[r][c] == oldCol: floodFill4(m, r,c, newCol=newCol, oldCol=oldCol) newCol += 1 -- http://mail.python.org/mailman/listinfo/python-list
