select all pixels with same color ?

thank you for answering me....

I like your idea , but I want to check just for the closed area , as in image up , just the brown color below the eye selected but the brown up the eye didn't

so how can i check if closed or not , and i don't wanna check all the image ( to make it faster ) ,just start checking from the selected pixel until didn't find same color around it so will stop checking

I was thinking about something like in a* pathfinding (only the open and closed list are of importance).

First, you get the coordinates of your initial click, and put it in the open list.

now while there are items on the open list, get the pixels around it, and put them on the openlist, if they share the color. After all of the pixels around are tested, you put the item on the closed list. So something like this:

 List<Vector2> openList;
 List<Vector2> closedLit;
 while (openList.Count > 0)
 {
 if (isTheSameColor(openList(0)+Vector2.up) && !onOpenOrClosedList(openList(0)+Vector2.up))
 {
 openList.Add(openList(0)+Vector2.up);
 }
 //repeat for other sides
 closedList.Add(openList(0));
 openList.Remove(0);
 }

In the end you are left with the closed list. It contains the coordinates of all the pixels you have selected.

This Code is completly unable to compile, and might have some logical gaps in it, but i hope it makes my point a bit clearer. For Example when trying to add a pixel at the edge of the image, this code might not work.

hey did u manage to do it cuz ill want to do the samething with no luck
