mapping world and screen by R.Tschaggelar

Mapping from screen ( integer) coordinates to world ( real) coordinates

Mirror symmetry around x axis:
Special case: y:=0 is in the middle of image. Then color of pixel (x, y) is the same as color of pixel (x,-y). :

Programs using this symmetry for drawing Mandelbrot set in special case:
Programs using this symmetry for drawing Mandelbrot set in general case:
General case: the program checks if y:= 0 is in the drawing region and then Source code in delphi
  1. axis of symmetry is out of range of drawing area (iYaxisOfSymmetry < iYmin )
