You're referring to "Deep Images"? That's a native 24 or 32-bit picture, you cannot use that on a regular Amiga.

We'll see. Do you happen to have a spatial algorithm, which is in C and not C++? I would like to avoid rewriting it.

And how does this relate to quantizing?

Either i remembered wrong, or it was an older PPaint, which did not supported it. PPaint 7.1 did; see above.

And how about 48-bit ones? 64? How about quantizing to a fix palette, or preserve/override colour registers?

Nope.
