<p>How do I manipulate images at the pixel level in C#?</p>

<p>I need to be able to read/modify each bitmap pixel RGB values separately. </p>

<p>A code sample would be appreciated.</p>

If you want speed, then
LockBits
.
See here for a good walkthrough by Bob Powell
. If you just want to edit a few, then
GetPixel
/
SetPixel
should do what you want.
