Combine 2 picture boxes into a new picture box - vb.net

Question

I have my pixBox1 which is fix, and unable to change the image
and pixBox2 is not fix which can change there color and rotate in here
i use OpenFileDialog function to put image inside those pixbox
so now how can i combine those two pixbox into my pixbox3?
i try this but it doesn't look like it's going to work:
Dim image As New Bitmap(pixBox1.Image)
Dim image2 As New Bitmap(pixBox2.Image)
Dim Image3 As New Bitmap(300, 300)
Dim g As Graphics = Graphics.FromImage(Image3)
g.DrawImage(image1, New Point(300, 300))
g.DrawImage(image2, New Point(300, 300))
g.Dispose()
g = Nothing
pixBox3.Image = Image3

Answer 1

This is kinda ugly and slow, but it basically sets all the pixels in image2 to be 50% transparent then draws it over the top of Image.
Dim image As New Bitmap(pixBox1.Image)
Dim image2 As New Bitmap(pixBox2.Image)
Dim Image3 As New Bitmap(300, 300)
Using g As Graphics = Graphics.FromImage(Image3)
'make 2nd bmp translucent
For Integer Xcount = 0 To image2.Width - 1
For Integer Ycount = 0 To image2.Height - 1
Dim c as Color = image2.GetPixel(Xcount, Ycount)
c = Color.FromARGB(125, c.R, c.G, c.B) '50% alpha
image2.SetPixel(Xcount, Ycount, c)
Next
Next
g.DrawImage(image1, New Point(0, 0))
g.DrawImage(image2, New Point(0, 0))
End Using
pixBox3.Image = Image3
As a side note, the Using block makes sure g is disposed no matter what happens.
