Floodfilling a small area on a large Bitmap?

Hi there,

I am trying to floodfill a small area on a large Bitmap using delphi commands.
Does anybody know how to do this and have only a small area of the Bitmap get
refreshed so as not to have the whole bitmap flash?

I can do this using WIN API calls, by specifying an invalidate region, but
not in delphi. The Delphi Floodfill command always refreshes the whole bitmap.

Any suggestions would be greatly appreciated!

Thanks in advance.
