Hi,

I can use c program
https://code.mathr.co.uk/mandelbrot-graphics/blob/HEAD:/c/bin/m-stretching-feigenbaum.c

to create image out.png

It works well, shows components of Mandelbrot set from right :

• main cardioid (period 1)
• period 2
• period 4
• period 8
• period 16
• period 32
• ...

transformed to make all have the same size

When I try to show more components of period doubling cascade ( out3000.png) I increase w to 3000 ( from the initial 1500)
It works , but main cardioid moves to the right  and left part of the image is empty.
How can I move it to the right?

TIA
