Putpixel

*** Shopping-Tip: Putpixel
Common name for a subroutine that takes two dimensinal coordiantes (x and y) and a color value as parameters, and draws a pixel on the screen by putting the color value in the computer's video RAM. Access to such routine, enables a computer user to display data graphically, which is important for intuition. A typical putpixel calculation in the C programming language can look like this:

(Y * height) + X * (bpp >> 3)

Where height is the max Y value, and bpp is bits per pixel. See also: * Pixel A method for drawing pixels using SDL.
