  • x : x coordinate where to print the text
  • y : y coordinate where to print the text
  • color : the color to use to draw the text to the screen
  • fixed : a flag indicating whether to fix the width of the characters, by default is not fixed
  • scale : font scaling
  • smallfont : use small font if true
