the ideal will be have a method as this:

TRichView.InvalidateRect(Rect)

and a flag ON OFF to avoid the automatic repainting of all the richview if I

change a image.

Example now is:

-> TPicture(AItemInsideRichview).Assign(ANewBitmap) -> the richview

repaint/format/invalidate all.

I like:

->AutoInvalidateAll:=False;

->TPicture(AItemInsideRichview).Assign(ANewBitmap)

->TRichView.InvalidateRect(RECT)

->AutoInvalidateAll:=True;

Kind Sergey, can you made this lil patch?

I think can be easy done by you, because I see that selection has already

map X,Y of objects to change.

Thank you.

Best regards.
