Examples
The following code example is designed for use with Windows Forms, and it requires PaintEventArgse, which is a parameter of the Paint event handler. The code performs the following actions:
Creates a Bitmap.
Sets the color of each pixel in the bitmap to black.
Draws the bitmap.
Private Sub SetPixel_Example(ByVal 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
private 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);
}
private:
void SetPixel_Example( PaintEventArgs^ e )
{
// Create a Bitmap object from a file.
Bitmap^ myBitmap = gcnew 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 );
}
