Parameters
- x
- The x-coordinate of the pixel to set.
- y
- The y-coordinate of the pixel to set.
- color
- A Color structure that represents the color to assign to the specified pixel.

Example
[Visual Basic, C#] The following example is designed for use with Windows Forms, and it requires PaintEventArgs e, which is a parameter of the Paint event handler. The code performs the following actions:
- Creates a Bitmap object.
- Sets the color of each pixel in the bitmap to black.
- Draws the bitmap.
[Visual Basic] Public Sub SetPixel_Example(e As PaintEventArgs) ' Create a Bitmap object from a file. Dim myBitmap As New Bitmap("Grapes.jpg") ' Draw myBitmap to the screen. e.Graphics.DrawImage(myBitmap, 0, 0, myBitmap.Width, _ myBitmap.Height) ' Set each pixel in myBitmap to black. Dim Xcount As Integer For Xcount = 0 To myBitmap.Width - 1 Dim Ycount As Integer For Ycount = 0 To myBitmap.Height - 1 myBitmap.SetPixel(Xcount, Ycount, Color.Black) Next Ycount Next Xcount ' Draw myBitmap to the screen again. e.Graphics.DrawImage(myBitmap, myBitmap.Width, 0, myBitmap.Width, _ myBitmap.Height) End Sub [C#] public void SetPixel_Example(PaintEventArgs e) { // Create a Bitmap object from a file. Bitmap myBitmap = new Bitmap("Grapes.jpg"); // Draw myBitmap to the screen. e.Graphics.DrawImage( myBitmap, 0, 0, myBitmap.Width, myBitmap.Height); // Set each pixel in myBitmap to black. for (int Xcount = 0; Xcount < myBitmap.Width; Xcount++) { for (int Ycount = 0; Ycount < myBitmap.Height; Ycount++) { myBitmap.SetPixel(Xcount, Ycount, Color.Black); } } // Draw myBitmap to the screen again. e.Graphics.DrawImage( myBitmap, myBitmap.Width, 0, myBitmap.Width, myBitmap.Height); }
