This is correct, for this reason, in the most recent version of

this handler, I am using 2 chars to store the new pixel value.

first char is a whole number from 0 to 255 and the second

char represent a decimal part from 0 to 99.

I will test if using 5 chars for storing the new pixel value.

In this way, the new pixel could store values of

0000.000000 that should be enough for this task...

After reading Mark's answer, I learned that using a numerical

ordered array to store pixel values could be really fast too.

This is another path to explore.
