I need to remake this function using the lockbit method.



 public void xPix(Bitmap bmp, int n, Color cx, Color nx)
{
try
{

for (int y = 0; y < bmp.Height; y++)
{
for (int x = 0; x < bmp.Width; x += (n * 2))
{
cx = bmp.GetPixel(x, y);
if (x + n <= bmp.Width - 1) nx = bmp.GetPixel(x + n, y);
bmp.SetPixel(x, y, nx);
if (x + n <= bmp.Width - 1) bmp.SetPixel(x + n, y, cx);
}
}
}
catch { }
}

    You suggest you need to remake this function using the "lockbit" method. I've never heard of that method. Perhaps you should explain what your code does, and why you think it needs to be faster, and where it is spending time, currently?
