### Sample Wu Antialiasing {#Heading5}
The true test of any antialiasing technique is how good it looks, so
let’s have a look at Wu antialiasing in action. Listing 42.1 is a C
let's have a look at Wu antialiasing in action. Listing 42.1 is a C
implementation of Wu antialiasing. Listing 42.2 is a sample program that
draws a variety of Wu-antialiased lines, followed by non-antialiased
lines, for comparison. Listing 42.3 contains **DrawPixel()** and
**SetMode()** functions for mode 13H, the VGA’s 320x200 256-color mode.
**SetMode()** functions for mode 13H, the VGA's 320x200 256-color mode.
Finally, Listing 42.4 is a simple, non-antialiased line-drawing routine.
Link these four listings together and run the resulting program to see
both Wu-antialiased and non-antialiased lines.
