((dbl) summ value taken for controll)

calculate mandelbrot for test (

(int) CLIENT SIZE X,
(int) CLIENT SIZE Y,
(dbl) paint map centre x,
(dbl) paint map centre y,
(dbl) paint map size x ,
(int) max number of iterations)
{

setup variables:

(dbl) paint map size y = paint map size x * CLIENT SIZE Y / CLIENT SIZE X

(dbl) per pixel delta x = paint map size x / CLIENT SIZE X
(dbl) per pixel delta y = paint map size y / CLIENT SIZE Y

(dbl) left top point x = paint map centre x - paint map size x * 0.5 + per pixel
delta x * 0.5
(dbl) left top point y = paint map centre y - paint map size x * 0.5 + per pixel
delta y * 0.5 ;


loop thru pixels:

for (CLIENT SIZE Y) j:
(dbl) c point imaginary = left top point y + j * per pixel delta y

for (CLIENT SIZE X) i:
(dbl) c point real = left top point x + i * per pixel delta x

fire point calculation:
(int) n = calculate n for mandelbrot escape ( c point real, c point
imaginary, max number of iterations )

summ value taken for controll += n

set pixel in client area (i ,j, palette [n]) ;
;
;

return summ value taken for controll
