Hi,
Please look at implementation :
procedure TLazIntfImage.Assign(Source: TPersistent);
var
Src: TLazIntfImage;
Desc: TRawImageDescription;
begin
if Source is TLazIntfImage then begin
Src:=TLazIntfImage(Source);
Desc:=Src.DataDescription;
Desc.Width:=0; // avoid side effects
Desc.Height:=0; // avoid side effects
DataDescription:=Src.DataDescription;
end;
inherited Assign(Source);
end;Why we set Desc.Width and Height to 0 and later we do not use "Desc" , but "Src.DataDescription" ?
-Laco.
