Hello Jerome,

I think this is a classical BitBlt. My problem are 800 FloatArrays,
each 300 entries.

BitBlt just has many many options. One rule is: one big BitBlt is
faster than many small BitBlts.

Right now i look into my code and I don't understand it in the time I
have. Sorry! But I have an Array of 256 Forms each representing a
possible shade of blue. That was necessary when a dot was bigger than
1 at 1 pixels.

But I know there are ways to fill a Form from an Array (ByteArray?) and
vice versa, search the list for storing an image in a method.

I didn't find BitBlt easy but it's robust.
