create circle image HELP!!

[OhGreen]

Okay, I quickly wanted to test this before responding so made an associated program as below:

Dim startx As Integer
    Dim starty As Integer
    Dim currentx As Integer
    Dim currenty As Integer
 
    Private Sub DrawCircle()
        Dim e As System.Drawing.Graphics
        e = PictureBox1.CreateGraphics
        e.CompositingQuality = Drawing2D.CompositingQuality.HighQuality
        e.SmoothingMode = Drawing2D.SmoothingMode.AntiAlias
        e.FillEllipse(Brushes.Lime, startx, starty, currentx, currenty)
    End Sub
 
    Private Sub Timer1_Tick(sender As System.Object, e As System.EventArgs) Handles Timer1.Tick
        Call DrawCircle()
        startx = startx + 5
        starty = starty + 5
        currentx = currentx + 5
        currenty = currenty + 5
    End Sub
 
    Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
        Timer1.Enabled = True
    End Sub

The above creates a continuous line of circles overlapping and growing larger on each tick of a timer within PictureBox1.

I'm not entirely sure what you're after, you seem to have posted two similar issues.

To make a smooth border like the first white circle use:

Dim bmp As Bitmap = New Bitmap(64, 64)
Dim g As Graphics = Graphics.FromImage(bmp)
g.CompositingQuality = Drawing2D.CompositingQuality.HighQuality
g.SmoothingMode = Drawing2D.SmoothingMode.AntiAlias
g.FillEllipse(Brushes.White, 8, 8, 48, 48)
bmp.Save("d:\dot.png")
