Setting Individual Pixel Colors in VB 2005

[fripper]

I want to generate a graphic in a picture box control where the color of
each pixel is determined by particular values calculated for each pixel.
These values are manipulated in such a way that I come up with three values
(each in the range 0-`55) and I want to use these for the RGB values of the
color of the associated pixel. My question is: In VB 2005 how do I set a
particular pixel to a color with a given set of RGB values? In VB 6 I used
the PSET function but it is not available in VB 2005.
Thanks.

Hi,

Use the graphics class fillellipse method with a diameter of 1.

In addition to the other comments:

Are you drawing on the screen or a Bitmap?

You can use Bitmap.SetPixel to set an individual Pixel on a bitmap.

Something like:

Dim bm As New Bitmap(256, 256)
For x As Integer = 0 To 256- 1
For y As Integer = 0 To 256- 1
bm.SetPixel(x, y, Color.FromArgb(x, y, 0))
Next
Next
Me.PictureBox1.Image = bm

Hope this helps
