how doi draw pixl by pixl

[Ivan D]

(planning to do this in C#)
plz, if you know tell me
Im interested in handling the drawing to a surface
manually pixel by pixel. For example I want to draw a
640x480 image according to some method I make, perhaps
each pixel is randomly colored. I know there is the set
pixel method, but thats not fast enough for such a large
surface. So is there a way for me to prepare the image
pixel by pixel without drawing it, and then send it to the
surface all at once. Also is there any way for me to take
advantage of hardware support in any way for this, that
would be very important if it is possible?
Thank you very much!!

You can override the paint method... For powerfull graphic stuff, take a
look at GDI, for example:

Unsafe code is probably the fastest way to go to draw pictures. Take a look
at the following article. It shows an example on how to effeciently set
every pixel of an image at a decent speed.
