Drawing Hello World :: The Rendering Process (in plain English)

Below are the steps required to draw “Hello World” on screen.

1. Set the current color to black
2. Fill the entire screen (using the current color)
3. Set the current color to white
4. Print “Hello World!” (using the current color and font)

So that Hello World’s font’s color is different from that of the screen we explicitly set both prior to filling the screen and printing our text.
