Subject: Re: TImageScrollBox AntiAliased OnProgress event? AntiAlias performance with large tiffs

Hi Brian,

Sorry for my lack of support. Just wish there were more hours in a day.

How big are you images?

I will make note to make the antialiastransform in TimageScrollBox public to allow setting the progress event handler.
