I've just started java recently, and I was getting into the graphics part of it. I was wondering if there was anyway to fill in a location with a color (like Turing's draw.fill command) in java.

What I pretty much did was create an isometric square using a bunch of drawlines and was hoping to fill it with a certain color, is there anyway to do this?

OR

is there a way to create an Isometric square with fill options besides using drawline commands?

[I'm using NetBeans 6.5.1 and JDK 5, and importing java.awt, java.swing atm]

Is there a method to draw a filled polygon?

Filling a closed area is very inefficient, but if you want to, the algorithm is something like this (pseudo code):

code:
function fillarea(x, y, srcCol, dstCol) {
    /* scrCol is the current colour to search for */
    if pixel @ [x,y] is srcCol {
        set pixel @ [x,y] to dstCol
        fillarea(x+1, y, srcCol, dstCol)
        fillarea(x-1, y, scrCol, dstCol)
        fillarea(x, y+1, srcCol, dstCol)
        fillarea(x, y-1, srcCol, dstCol)
    }
}


There are more efficient methods, but they are harder to implement, and still would run slower than something that just drew a filled polygon.

Thanks Dty, found the polygon you were talking about, solve my problems. Thanks again!
