Mandelbrot graphic test

Contributions to this software library are always welcome. Please ensure that you post program listings rather than .raw files. They give a reasonable idea of what your program does without having to load them into a DM42 and you can also include comments in your code. Check out the following link for a decoder/encoder: http://www.swissmicros.com/dm42/decoder/

You can then copy/paste the listing and post it in "code" tags.

Great to have the Mandelbrot set available on the DM42. Thank you!
I'd suggest one minor change related to rendering. Personally I like the escape time based coloring. This requires only a minor change in the program.

Here is the modified program:

Sorry but, donloaded your program and I get the same result (no escape time based color) as initial version.
Did I miss something ?

Fantastic ! As this calc. I have added a benchmark prog to add on the grap iterations' number + time to complete the figure
Not time now but I will come back with pictures + programs

I too do not get the nicer escape value image.

What are the parameters people are using to get the pretty / properly scaled M-set image?

Thank you

Added my "bench" programs to visualise iterations' number + running time. Also modified the Mandel program to interact with the second one.
You can see impact of iterations' number compared to time spent to draw the set

Now I don't know how to put the raw files here, if someone can help me...

Ooops, I think I have mixed some pictures as some runs were made on usb power supply and some not (3x slower).

Hello Stéphane,
You may add your raw files as zip files, like in
viewtopic.php?f=19&p=9285&sid=d3139eb4c ... 3266#p7940
