Paint [Resolved (FLOODFILL!)]

[Ruku]

Let's say I got a black circle drawned on a bitmap object, in the middle of a white background...

How do I paint the black circle to red...

Don't tell me to paint another circle over it... , I'm looking for a way to paint a single color from a specifyed point to another color...

I don't really feel like going through each pixel... it's my last resort, but my guess is that there is something out there way easier... right?

I've tried...

'Dim p As New Region(New Rectangle(x, y, x + 1, y + 1))
                    'Dim newFillMode As System.Drawing.Drawing2D.FillMode = System.Drawing.Drawing2D.FillMode.Alternate
                    'Buffer.FillRegion(MyPen.Brush, p)
 
                    Dim Point1 As New PointF(x, y)
                    Dim Point2 As New PointF(x + 1, y)
                    Dim Point3 As New PointF(x, y + 1)
                    Dim Point4 As New PointF(x + 1, y + 1)
                    Dim pF As PointF() = {Point1, Point2, Point3, Point4}
 
                    'Buffer.FillPolygon(MyPen.Brush, pF, Drawing2D.FillMode.Winding)
 
                    Dim i As New System.Drawing.Drawing2D.GraphicsPath(pF, Nothing)
                    Buffer.FillPath(MyPen.Brush, i)

Plenty of crap that always returned the same kind of result:

I got a square and it just does the same as clearing the section to another color...

You use a Brush object in order to fill in shapes...

Here's a link to sample code in filling in shapes..

yeah, I know that... ok, look at attachement for a better idea of what I want...

so basically, to fill a color with another... stopping at another color's touch...

So you basically want a floodfill routine then?

Google "FloodFill Algorithm"

hehe, alright, so I really don't have any choice but to go through each pixel then... , I'll like it up

thx for keywords!
